`Ardent` launches Postgres sandboxes for coding agents without DB migration

Production-like DB branches spin up in under 6s without moving off your current hosted Postgres. Useful if agent-written schema or data changes need realistic testing before they touch prod.

• —It uses logical replication plus DDL triggers instead of physical replication, so existing hosted Postgres setups can adopt it without a platform move.
• —The stack fans replication through Kafka and uses Neon-style branching, targeting sub-6-second clones even at TB scale.
• —A proxy layer issues custom Postgres URLs, adds finer-grained clone access control, and reduces raw credential exposure.
• —Pre-return SQL hooks support anonymization and branch mutation, which makes PII redaction part of the sandbox flow instead of a separate step.
