Ardent
Ardent is a managed database branching platform that creates isolated, fast copies of production PostgreSQL databases for coding agents and development teams. Using a copy-on-write architecture, it can instantiate a full branch of a database in under 6 seconds, regardless of the underlying dataset size, and each clone is isolated at both the storage and compute levels. This allows AI coding agents and developers to safely test, clean, migrate, and verify changes against realistic data without any risk to production systems. The platform is designed for terabyte-scale data with automatic compute scaling that drops to zero when idle, ensuring cost efficiency. It supports integration with popular providers such as Supabase, AWS RDS, and PlanetScale, replicating database extensions, authentication, and configuration specifics. Ardent provides a CLI and web interface to manage branch creation and lifecycle, enabling teams to adopt git-like branching workflows for their databases. Common usage scenarios include validating database migrations, enabling agents to perform data cleanup and deduplication, executing backfills, and verifying application code before release. Ardent reduces data drift, because agents work on a 1:1 copy of production, eliminating the inaccuracies of synthetic seed data. It is built to accelerate release cycles and is trusted by Y Combinator-backed startups and data-intensive companies.

Problem solved
Traditional database replications are slow, expensive, and risky, requiring long wait times and full storage duplication. Ardent solves this by providing near-instantaneous, storage-efficient branching for PostgreSQL, enabling coding agents to test against an exact copy of production safely. This removes the need for inaccurate seed files and prevents agent-generated changes from affecting live systems.
Use cases
- Test database migrations against a production clone
- Allow coding agents to run data cleaning and deduplication scripts
- Perform backfills on an isolated copy of the database
- Validate AI-generated SQL or database code in a sandbox
- Create per-pr or per-agent database branches for safe development
- Run analytics or regression tests on a fresh snapshot of data
- Compare performance of schema changes without impacting production
Audience
- Developers
- ML Engineers
- Data Scientists
- Startups
