Launch HN: Ardent (YC P26) – Postgres sandboxes in seconds with zero migration | Hacker News

Ardent launched a tool for near-instant PostgreSQL sandboxes cloned from production data.

It uses logical replication, DDL triggers, Kafka-based scaling, and copy-on-write infrastructure to keep sandboxes fast and branchable.

The product is designed to let AI coding agents test changes safely without touching live databases.

Optional anonymization and access controls help reduce PII and security risks in realistic test environments.
