Db2rest

DB2Rest is an open source service that puts an instant REST data API in front of an existing database, removing the need to hand write a data access layer. Developers point it at a database and immediately get HTTP endpoints for reading and writing data, which lets frontend and backend teams build against the data without writing boilerplate persistence code. It suits developers building new applications, teams integrating systems that need to share data, and organizations that want to expose legacy databases to modern applications or machine learning work without rewriting them. The project addresses common problems of hand built data layers, including connection leaks, transactional inconsistency, inefficient batching, data leaks and SQL injection. It avoids object relational mapping overhead, uses a single round trip to the database, needs no code generation or compilation, and supports query caching and batching. It can run on premises, on bare metal, in virtual machines, in Docker or Kubernetes, or on any cloud. The latest release noted on the site is v1.6.5 from July 2025, which added SQLite support. DB2Rest is free open source software. The site has no pricing page and does not publish any paid plan or commercial support tier. The project's home page also carries a claim that it can speed up development thirtyfold; buyers should treat that as the vendor's own framing rather than a measured benchmark.
