Ardent

Ardent is a database branching platform for Postgres that lets developers and AI coding agents clone any production or development database in seconds into fully isolated, disposable branches. Each branch is isolated at both the compute and storage layers using copy-on-write, autoscales to zero when idle, and never touches production, so agents and CI/CD pipelines can run migrations, backfills, destructive tests, and risky experiments against production-like data with zero blast radius. Ardent exposes a REST API (api.tryardent.com), a first-party npm CLI (ardent-cli), and connectors for Supabase, AWS RDS, PlanetScale, and self-hosted Postgres 13+.

Ardent publishes 6 APIs on the APIs.io network, including v1-api-keys API, v1-branching API, v1-connectors API, and 3 more. Tagged areas include Company, Database, PostgreSQL, Database Branching, and Developer Tools.

Ardent’s developer surface includes CLI, sandbox, authentication, documentation, API reference, getting-started guide, support, and 20 more developer resources.
