Ardent offers instant Postgres database cloning for safe coding agent testing

Summary

Ardent is a Y Combinator-backed startup that offers a database branching tool for Postgres. It allows developers and coding agents to create isolated, 1:1 copies of production databases in under 6 seconds, enabling safe testing, data cleaning, and migration without risking production data. The clones are isolated at both compute and storage levels, scale to terabyte sizes without slowdown, and provide a zero-blast-radius environment for code verification.
