QQueue is an open-source email platform that provides one system to send emails via API, manage campaigns, and schedule emails simply and securely on your own server at zero cost. It’s a TypeScript monorepo: an Express + Prisma API, a Vite React operator dashboard, and BullMQ workers that pull jobs from Redis and send through a provider-agnostic email engine. The whole stack deploys with one command so it's simple to setup.
