Xata

Xata is an open-source, branch-native PostgreSQL platform designed for software engineering teams and AI coding agents. It provides isolated Postgres database environments for every pull request, preview, or development task, eliminating migration conflicts and test failures caused by shared staging databases.

Built on standard PostgreSQL, Xata uses copy-on-write storage to clone databases in seconds without duplicating full datasets. It features scale-to-zero compute to automatically hibernate idle branches and wake them instantly on the first query without connection timeouts or delays.
