Ardent
Clone any Postgres database in six secondsInstant isolated Postgres branches for safe testing
Highlights
What you can do with it
- Coding agents test AI database code against a real copy instead of seed files
- Data engineering teams run migration tests on a production branch safely
- AI teams clean and train on a production copy without risking live data
How to use it
- 1 Visit tryardent.com and register an account
- 2 Connect your Postgres database, such as Supabase, AWS RDS, or standard Postgres
- 3 Select a database and click Create Branch, then wait a few seconds
- 4 Run tests, cleaning, or migration work on the branch
- 5 Keep or delete the branch when you are finished
Who it is for
Pros
- Free to use, with fast six-second cloning
- Isolated branches keep production safe during testing
- Unlimited branches and efficient difference-based storage
- Compute scales to zero, so you are not locked into idle capacity
Limitations
- Currently focused on Postgres, including Supabase, AWS RDS, and standard Postgres
- More database types are planned but not yet available
- Free-to-use terms and future pricing may change over time
- Teams still need to manage branch hygiene and cleanup
What Ardent is
Ardent is a database branching platform developed by ArdentAI Inc and backed by Y Combinator. It uses copy-on-write technology to create an isolated copy of any PostgreSQL database within six seconds, no matter how large the database is, without causing any risk to the production environment. Coding agents and developers can then perform data cleaning, migration testing, record backfilling, and query testing on a one-to-one copy of the real system. Each branch is isolated at the compute and storage level, storage stays efficient because only differences from the parent are kept, and compute can scale to zero when idle. The service is free to use and is built to help teams apply AI safely at production scale.
What you can do with it
- Clone any Postgres database, including Supabase, AWS RDS, and standard Postgres, in about six seconds.
- Run data cleaning, migration tests, backfills, and query tests on an isolated copy.
- Create unlimited branches instead of the fifteen to twenty copies typical of traditional replication.
- Save storage by keeping only the differences, and let compute scale to zero when idle.
Who it is for
- Coding agents that need a real copy of production data to test against.
- Developer teams running migrations, cleaning, and backfills without production risk.
- Data engineering and AI native teams that work with large-scale data.
What to watch out for
Ardent is currently focused on PostgreSQL, covering Supabase, AWS RDS, and standard Postgres, so other database types are not yet supported even though more are planned. The service is described as free to use, but terms and any future pricing can change, so confirm current details before you depend on it. Teams still need to manage branch hygiene, such as cleaning up branches that are no longer needed. Because it touches production copies, follow your organization's data-handling rules when using it on sensitive systems.
