Index.dev alternatives: 10 platforms compared on what you can actually verify
Ten Index.dev alternatives compared on published rates, vetting method and third-party ratings, with the gaps named where a platform publishes nothing.

Table of contents
If you are weighing Index.dev alternatives, start with what you can verify before speaking to sales. On 25 August 2026, only two of the 11 platforms checked published an hourly rate on their own websites. Index.dev was not one of them. Six others had rate bands listed on Clutch. The remaining platforms provided no pricing a buyer could use before a sales conversation.

Read 25 August 2026. Every cell reading Not published means the platform's own pages were read that day and contained no figure. That is a statement about the page, not an accusation about the company.
That makes pricing transparency a useful starting point for comparison. This guide looks at what each platform actually discloses, including rates, independent reviews, and trial or guarantee terms. The goal is not to rank marketing claims. It is to show what a buyer can verify for themselves.

What is Index.dev and who is it for?
Index.dev is a vetted talent marketplace for companies looking to hire senior engineers. It positions itself around larger hiring engagements rather than one off freelance tasks.
The company says its database contains 2.5 million professionals, with the top 1% selected for its network. It also says 30,000 engineers have been interviewed by humans. Index.dev says there are no upfront costs and that companies pay only when they hire. These figures come from Index.dev itself. The selection figure has no published methodology, so it is best treated as a company claim rather than an independently verified fact.
The more useful information is what Index.dev does not publish. Its pricing page and developer hiring page currently return 404 errors. The homepage does not state an hourly rate, pricing range or markup percentage. Its Clutch profile gives the company a 4.9 out of 5 rating from 18 verified reviews. It also lists a minimum project size of $50,000 or more, but provides no hourly rate band.
That $50,000 minimum matters. Index.dev is not an obvious fit for a founder who needs one engineer for a short engagement. If that is your situation, several alternatives below may be more relevant.
The wider freelance market is also changing. Upwork reported $966 million in gross services volume for Q2 2026, down about 4% year over year. It attributed some of the pressure to AI automation. Its marketplace take rate rose to 19.8%. This does not show that demand is leaving vetted talent platforms, because there is no reliable dataset measuring that segment. It does show that open marketplaces are facing pressure as AI changes how companies buy technical work.
What are the best Index.dev alternatives in 2026?
The best Index.dev alternative depends on what you need to verify before hiring. RocketDevs is the strongest option if published pricing matters. Lemon.io is more suitable for smaller engagements. Toptal makes more sense when brand recognition and a large vetted network matter more than price transparency. Arc.dev is useful if you want both freelance and permanent hiring.
The comparison below scores 11 platforms based on information a buyer can actually check. Review counts are included because a 5.0 rating from one review does not carry the same weight as a 4.8 from 53 reviews.
1. RocketDevs
RocketDevs stands out for publishing its rates and explaining how its developers are assessed. It is one of only two platforms in this comparison with pricing published on its own website.
Pros
- Publishes rates by tier:
$9.99/hrAssociate,$21.99/hrMid-senior and$30.99/hrSenior. - States that each developer undergoes
6-8 hoursof assessment. - Offers a
14-daymoney-back trial. - Publishes its acceptance figure with a denominator: 2% accepted from
14,233applicants in Q1 2026. - Has no minimum project size, unlike several competitors with a $50,000 floor.
Cons
- No reachable Clutch profile. The RocketDevs Clutch page returned HTTP 404 during this research.
- Its G2 rating of
5.0/5comes from 3 reviews. Its Google rating of4.9/5comes from 15 reviews. - The 2% acceptance figure is self-reported and has not been independently audited.
- It has less brand recognition than Toptal or Upwork.
Third-party rating: G2 5.0/5 from 3 reviews; Google 4.9/5 from 15 reviews. Both were checked on 25 August 2026. No reachable Clutch profile.
Best for: A founder or small team hiring one to five engineers who wants to see the price before speaking to sales.
2.Index.dev
Index.dev is designed for companies looking for larger engineering engagements rather than small freelance tasks.
Pros
- No upfront cost and payment only when you hire, according to Index.dev.
- Clutch rating of
4.9/5from 18 verified reviews. - Says its 30,000 engineers have been interviewed by humans.
- Suited to companies buying a defined engineering engagement.
Cons
- No published rate was found. Two pricing related pages returned 404.
- Clutch lists a minimum project size of $50,000 or more.
- Its top 1% claim is based on company supplied figures with no disclosed methodology.
- No trial or guarantee term was found.
Third-party rating: Clutch 4.9/5 from 18 verified reviews, checked on 25 August 2026.
Best for: A funded company buying a larger engineering engagement where the $50,000 minimum is not a problem.
3. Toptal
Toptal remains one of the strongest options for buyers who value brand recognition and a large established talent network.
Pros
- Well known in the category, which can make internal approval easier.
- Has the largest verified review sample in this comparison, with 53 Clutch reviews.
- Describes a five-step screening process that includes a one to three week test project.
- Covers design, finance and product as well as engineering.
Cons
- Does not publish a rate on its own website. Clutch lists a $100 to $149 hourly band.
- Its "fewer than 3%" acceptance figure has no published denominator or independent audit.
- Clutch lists a minimum project size of $50,000 or more.
- Its hiring guarantee page returned 404 during this research, so the guarantee could not be verified.
Third-party rating: Clutch 4.8/5 from 53 verified reviews, checked on 25 August 2026.
Best for: Enterprise buyers who need a recognised vendor and have a substantial hiring budget. If brand recognition is the main constraint, Toptal may be the better choice regardless of its weaker pricing transparency.
4. Turing
Turing is built for companies that need access to engineers across multiple countries and time zones.
Pros
- Says its talent network spans 140 or more countries.
- Clutch lists a $50 to $99 hourly band.

Third-party rating: Clutch 5.0/5 from 4 reviews, checked on 25 August 2026.
Best for: Companies hiring across several time zones where geographic reach matters more than pricing clarity.
5. Lemon.io
Lemon.io is one of the more accessible choices for smaller engagements. Its Clutch pricing band is also the lowest among the vetted platforms in this comparison.
Pros
- Clutch lists a $25 to $49 hourly band.
- Clutch lists a $1,000 minimum project size, which is much lower than the $50,000 floors found elsewhere.
- States a matching time of about 24 hours.
- Focuses heavily on startups.
Cons
- Its own pricing page does not publish a rate, fee or guarantee figure.
- Its stated 1.2% acceptance rate has no published denominator or independent audit.

6. Arc.dev
Arc.dev is one of only two platforms in this comparison with pricing published on its own website. It also supports both contract and permanent hiring.
Pros
- Publishes a $15 to $110+ hourly range.
- Publishes a permanent placement fee of 20% of annual salary.
- Offers a risk-free trial of up to two weeks.
- Supports both freelance and permanent hiring.
Cons
- No reachable Clutch profile was found.
- The $15 to $110+ range is extremely broad, which limits its usefulness for budgeting.
- A 20% placement fee can become significant for senior permanent hires.
- Has less brand recognition than Toptal or Upwork.
Third-party rating: Not verified. The Clutch profile returned HTTP 404 during this research. G2 could not be reached, so no G2 rating was substituted.
Best for: Teams that want contract and permanent hiring through the same platform and can work with a wide price range.
7. Braintrust
Braintrust takes a different approach to marketplace fees. It states that talent pays no platform fees, although the client side still requires clarification.
Pros
- States that talent pays zero platform fees.
- Clutch lists a $150 to $199 hourly band.
- Its network-owned model may appeal to senior contractors.
- Does not state a client-side percentage for its talent marketplace.
Cons
- Has the lowest Clutch score in this comparison at 4.4/5.
- The rating comes from only 5 reviews.
- Its Clutch price band is the highest in this comparison.
- No published trial or guarantee was found.
- Client-side costs are not fully explained on the information reviewed.
Third-party rating: Clutch 4.4/5 from 5 reviews, checked on 25 August 2026.
Best for: Buyers looking for senior contractors who prefer a marketplace that does not charge talent a platform fee.
8. Andela
Andela is aimed more at larger organisations than small teams. Its main differentiator is the scale of its stated technology network.
Pros
- States that it has 17,000 certified AI-native engineers and 200,000 trained technologists.
- Has an established enterprise presence.
- Positions itself around AI capable engineering talent.
- Has strong general market visibility.
Cons
- Publishes no rate.
- No reachable Clutch profile was found.
- Its
4.7/5G2 rating is displayed on its own website and could not be checked at G2. - The certified and trained network figures describe different populations, and the distinction is not fully defined.
- No published trial or guarantee was found.
Third-party rating: Not verified. Andela displays a self-reported G2 score of 4.7/5 from 329 reviews. G2 could not be reached during this research and the Clutch profile returned 404.
Best for: Larger organisations staffing AI work at scale where an established vendor relationship matters more than published pricing.
9. Revelo
Revelo focuses on Latin American talent and gives buyers something several competitors do not: a clearly stated trial period.
Pros
- Offers a
14-dayrisk-free trial. - Uses a pay-only-if-you-hire model.
- Has a perfect
5.0/5Clutch rating. - Its Latin American focus provides strong time zone overlap with US teams.
Cons
- The Clutch rating comes from only 1 verified review.
- Publishes no rate.
- Its regional focus limits access to talent outside the Americas.
- Its
4.7/5G2 score is self-reported and could not be independently verified.
Third-party rating: Clutch 5.0/5 from 1 verified review, checked on 25 August 2026.
Best for: US companies that want overlapping working hours and value a clearly stated trial period.
10. Gun.io
Gun.io has a long-standing presence in the senior freelance engineering market, but very little could be independently verified during this research.
Pros
- Established reputation among senior US freelance engineers.
- Has a visible developer community presence.
- Focuses on experienced contractors.
- Smaller and more specialised than large marketplaces.
Cons
- Its website and pricing page returned HTTP 403 during this research.
- No rate, trial term or vetting details could be verified.
- No reachable third-party rating was found.
- The 403 is a limitation of this research, not evidence that the company does not provide these details to customers.
Third-party rating: Not verified.
Best for: Buyers who already know Gun.io and can obtain its current terms directly. Based on the available evidence, it is difficult to recommend it to a new buyer.
11. Upwork
Upwork is fundamentally different from the other platforms here. It is an open marketplace rather than a vetted talent service, so the screening burden falls on the buyer.
Pros
- By far the largest talent marketplace in this comparison.
- Its financial reporting provides independently disclosed business metrics.
- Reported a 19.8% take rate on gross services volume in Q2 2026.
- Has no minimum engagement, making it suitable for very small tasks.
- Has the strongest developer-community presence in this comparison.
Cons
- It is not a vetted talent platform. Screening is the buyer's responsibility.
- Gross services volume fell about 4% year over year in Q2 2026.
- The 19.8% take rate represents a real marketplace cost.
- Quality varies much more widely than on the specialist platforms.
Third-party rating: Not verified as a rating. Its financial disclosures provide stronger evidence for the metrics used here than a directory score.
Best for: A defined, lower-risk task where you have the technical knowledge and time to screen candidates yourself.
How much does each platform cost per month?
At 160 hours, roughly one full time working month, the platforms with published or directory listed figures range from about $1,598 to $31,840. RocketDevs has the lowest published rate in this comparison, while Braintrust has the highest Clutch supplied range. Seven of the 11 platforms cannot be given a monthly cost because they do not publish a usable client rate.
The figures are not all the same kind of evidence. A vendor published rate appears on the company's own website and can be used for budgeting before a sales call. A Clutch band is a range supplied by the company to a third party. It is useful for shortlisting, but it is not a quote and should not be treated as independently verified pricing.
The table below keeps those sources separate:
The distinction matters when you are trying to build a hiring budget. A published rate lets you model your costs before contacting a vendor. A directory supplied range gives you an indication, but the actual price still needs to be confirmed.
Four platforms cannot be given a monthly cost from the available evidence. That is not a gap in the table. It is the finding.
If you need to model a year of engineering spend before speaking to sales, those platforms leave you without enough information to do it.
Our breakdown of the wider cost of hiring a remote developer also looks beyond the headline hourly rate and works through the other costs that can affect the final figure.
How do these platforms vet and how would you tell?
The honest answer is that you usually cannot tell from the outside. Most platforms in this category describe their vetting process in broad terms, but they do not publish enough detail to independently assess how candidates are tested or how consistently they are scored. Their acceptance rates are also self reported, which makes them difficult to compare.
Four platforms in this comparison publish an acceptance figure. Toptal says it accepts fewer than 3% of applicants. Index.dev says it selects the top 1%. Lemon.io reports a 1.2% acceptance rate. RocketDevs reports a 2% acceptance rate. These numbers may sound precise, but they do not necessarily measure the same thing.
None of the platforms explains exactly what counts as an applicant, how long the measurement period is, or whether the figures have been independently verified. A candidate who submits an application may not be counted in the same way across platforms. Putting all four percentages into one ranking would therefore create a level of precision that the underlying evidence does not support.
RocketDevs provides one additional piece of information. Its 2% figure is based on a disclosed denominator of 14,233 applicants in Q1 2026. That makes the figure easier to interpret than an unexplained percentage. It is still a company reported figure, however. A disclosed denominator is useful evidence, but it is not an independent audit.
The research on personnel selection gives us a better way to think about vetting. A major meta analysis published in Psychological Bulletin in 1998 found that general mental ability combined with a work sample test had a mean validity of .63. General mental ability combined with a structured interview produced the same figure.
A 2024 meta analysis in the Journal of Applied Psychology revisited earlier estimates and found that many had been overstated. Its revised figures were lower by roughly .10 to .20 points, with structured interviews ranking particularly strongly. Earlier research based on 245 coefficients from 86,311 people also identified structure as an important factor in selection validity.
That distinction matters because research measures the quality of the selection method, while marketing often measures the number of stages. A platform might advertise four or five stages of screening. That does not tell you whether candidates are assessed consistently. A shorter process can be stronger if every candidate completes the same relevant task and is scored against the same criteria.
The useful question to ask a vendor is therefore not simply, "How many stages are in your vetting process?" Ask whether the interviews are structured. Ask whether every candidate completes the same assessment. Ask whether the scoring rubric is fixed before the interview and whether candidates are assessed against the same criteria.
The quality of the answer matters too. A vendor that can clearly explain its process gives you something you can evaluate. A vendor that responds with another percentage or a list of screening stages has given you marketing information rather than evidence.
There is another disclosure signal worth considering: developer community attention. A Hacker News search conducted on 25 August 2026 found the following numbers of story titles mentioning each platform: Upwork appeared in 287, Toptal in 95, Andela in 68, Braintrust in 24 and Gun.io in 11. Lemon.io, Arc.dev, Index.dev and RocketDevs did not appear in the search. Turing was excluded because the search could not reliably distinguish the company from references to Alan Turing.
This does not measure vetting quality or hiring performance. It measures visibility among a particular developer community. It is included because a fair comparison should report relevant signals even when they do not favour the platform being recommended.
The bigger lesson is simple: do not confuse a difficult sounding process with a validated one. Ask what candidates actually do, how the work is scored and whether the same standard is applied to everyone. That tells you considerably more than an impressive acceptance percentage.
Which Index.dev alternative should you pick?
There is no single winner. The right Index.dev alternative depends on what matters most to your hiring decision. If you need a price before speaking to sales, RocketDevs or Arc.dev are the clearest choices. If you need a small engagement, Lemon.io or RocketDevs are easier to use. If internal approval depends on brand recognition, Toptal has the strongest case.
| If your constraint is | Pick | Why |
|---|---|---|
| Budget, and you need the price today | RocketDevs or Arc.dev | They are the only two platforms in this comparison publishing a rate on their own websites. |
| A small engagement under $5,000 | Lemon.io or RocketDevs | Lemon.io lists a $1,000 minimum on Clutch, while RocketDevs has no minimum project size. |
| Internal approval needs a known name | Toptal | It has the largest verified review base in this comparison and stronger brand recognition. |
| Same time zone work with the Americas | Revelo | Its regional focus provides strong overlap with US teams and it states a 14-day trial. |
| Time zone breadth across many countries | Turing | It says its talent network spans 140 or more countries and has a mid-market Clutch band. |
| Senior contractors with no talent-side platform fee | Braintrust | It clearly states that talent pays no platform fees. |
| Enterprise AI staffing at volume | Andela | Its stated network is the largest in this comparison and its model is suited to procurement-led enterprise buying. |
| A defined task you can screen yourself | Upwork | There is no minimum engagement, the talent pool is much larger and its take rate is publicly disclosed. |
| Risk transfer before you commit | RocketDevs, Arc.dev or Revelo | These are the three platforms in this comparison that state a numeric trial or guarantee window. |
The choice becomes easier if you separate what you need from what you are willing to compromise on. Price transparency favours RocketDevs and Arc.dev. Smaller projects favour Lemon.io and RocketDevs. Brand recognition favours Toptal. Geographic coverage points towards Turing or Revelo depending on where your team is based.
The most important point is that a platform should not win simply because it has the highest acceptance rate or the strongest marketing claim. Look at what you can verify before you commit. Published pricing, minimum project size, trial terms and a clearly described assessment process are more useful when you are making an actual hiring decision.
For related comparisons, see our guides to Toptal alternatives, Lemon.io alternatives and the wider market of remote developer platforms.
Where RocketDevs sits
RocketDevs performs well on the criteria used in this comparison. That is partly because those criteria were chosen deliberately. The point is not to pretend the comparison is neutral in every possible dimension. It is to be clear about what is being measured and apply the same standard to every platform.
The strongest part of the RocketDevs case is pricing transparency. It publishes rates of $9.99/hr for Associate, $21.99/hr for Mid-senior and $30.99/hr for Senior. That lets a buyer estimate costs before speaking to sales.
Its developer assessment is also stated in hours, at 6-8 hours per developer, rather than being described only as a series of screening stages. RocketDevs reports a 98%+ applicant rejection rate, with the top 2% accepted, and publishes the denominator behind that figure. The number is still self reported, but the additional detail makes the claim easier to evaluate.
The 14-day money-back trial provides another useful signal. A buyer can test the arrangement before committing fully. That shifts some of the risk away from the customer rather than asking them to rely entirely on claims made before hiring.
RocketDevs also has clear weaknesses. It has no reachable Clutch profile, while six competitors in this comparison have one. Its G2 rating of 5.0/5 comes from only 3 reviews. Its Google rating of 4.9/5 comes from 15 reviews. Neither sample is large. RocketDevs also appears in zero Hacker News story titles in the search used for this comparison.
Those gaps stay in the comparison because they are real. A useful comparison should not remove inconvenient evidence simply because it weakens the recommended platform.
So the conclusion is narrow rather than universal. If your priority is seeing the price before a sales call and having a stated trial period, RocketDevs is one of the strongest options in this set. If those are not your priorities, another platform may fit your situation better.
For more information on the hiring model, see our guide to hiring pre-vetted developers. You can also start by looking at the currently available vetted developers.
Conclusion
The best Index.dev alternative is not necessarily the platform with the biggest talent pool or the most impressive acceptance rate. It is the one that gives you enough information to make a sensible decision before you commit.
This comparison found a clear divide. Some platforms publish their rates. Others provide only directory supplied ranges. Several provide no usable pricing at all. The same problem appears with vetting. Acceptance percentages sound precise but without a denominator, methodology or independent verification they are difficult to compare.
That does not make Index.dev a bad choice. It means buyers should look beyond the headline claims. If you need a larger engagement and are comfortable discussing pricing directly, Index.dev may still fit. If you need transparent pricing for a smaller engagement, RocketDevs or Lemon.io may be easier to evaluate. Toptal remains compelling when brand recognition matters. Upwork makes sense when you have the technical ability to screen candidates yourself.
The useful question is therefore not "Which platform claims to have the best developers?" It is "What can I actually verify before I spend money?"
Price you can read. Vetting methods you can understand. A trial you can test. Those are the signals that reduce uncertainty before the hiring decision. The platforms that provide them make comparison easier because the buyer does not have to take everything on trust.
Frequently asked questions
Is Index.dev legitimate? Yes. Index.dev has a verified Clutch profile with a 4.9 out of 5 rating from 18 reviews. Clutch also lists 50 to 249 employees. Index.dev states on its own website that customers pay only when they hire.
The main concern is not legitimacy. It is transparency. Index.dev does not publish an hourly rate, and Clutch lists a minimum project size of $50,000 or more. That makes it better suited to larger engagements than to buyers looking for one developer on a smaller project.
How much does Index.dev cost? Index.dev does not publish an hourly rate. Its pricing page and developer hiring page both returned HTTP 404 on 25 August 2026. The homepage also contained no hourly rate or markup figure when reviewed.
The only usable pricing information is its Clutch listing, which shows a minimum project size of $50,000 or more but no hourly band. A buyer therefore needs to contact Index.dev to get a specific price.
What is the cheapest alternative to Index.dev?
Based on the figures available in this comparison, RocketDevs is the cheapest alternative with a published rate. Its Associate tier costs $9.99/hr, or $1,598.40 for 160 hours. Arc.dev starts at $15 per hour on its published rate card. Lemon.io's Clutch supplied range starts at $25 per hour.
The comparison cannot establish the absolute cheapest option because several platforms publish no usable rate. A lower price may exist, but there is no public figure to verify it.
Which Index.dev alternative has the strictest vetting? There is no reliable way to determine that from the published evidence. Toptal says it accepts fewer than 3% of applicants. Lemon.io reports 1.2%. RocketDevs reports 2%. Index.dev's published figures imply a similar level of selectivity.
These percentages are self reported. The platforms do not disclose enough about their methodology to make the figures directly comparable, and none provides an independent audit.
A better question is how the candidates are assessed. Structured interviews, consistent assessments and fixed scoring criteria provide more useful evidence about a vetting process than an acceptance percentage alone.
Do any of these platforms offer a money-back trial? Yes. Three platforms in this comparison publish a specific trial or guarantee period.
- RocketDevs:
14-daymoney-back trial. - Revelo:
14-dayrisk-free trial. Start with a vetted developer. - Arc.dev: Risk-free trial of up to two weeks.
Toptal's guarantee page returned 404 during this research, so its current terms could not be verified. The remaining platforms did not publish a numeric trial or guarantee period that could be confirmed during the research.
