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 21 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/ardent: open an issue to ask a question, or submit a pull request to add artifacts.
