Database Forking: Create Production Clones for Testing in Minutes

Testing against realistic data is the difference between catching bugs before production and catching them in production. But getting a faithful copy of your production database into a staging environment usually means writing export scripts, waiting for dumps to transfer, provisioning infrastructure, and importing the data. For a 100 GB PostgreSQL database, that process can take hours and requires someone to babysit it.

FoundryDB's fork endpoint eliminates this entire workflow. One API call creates a fully independent copy of your database, running on its own VM with its own credentials, restored from a backup of the source service. The source database is never touched. The fork is provisioned, restored, and ready for connections in minutes.
