NATS and JetStream are powerful, but day-to-day operations are spread across CLI commands, monitoring endpoints, and separate dashboards. Cracker provides one local interface for topology, streams, consumers, message inspection, and guarded changes. It is currently in private preview; public installers are not yet available.
How it will work
1. View the topology
See servers, JetStream status, streams, consumers, and KV/Object inventory across a NATS estate — the same 'see the estate' job Concord does for Patroni.
2. Browse subjects safely
Peek and tail messages with redaction by default, wildcard warnings, and no cloud upload — personal data in payloads stays on the operator machine.
3. Guarded publish and ops
Run publish, purge, or consumer changes behind a preflight → typed confirm → audit flow — never a bare command against production.
Concord for Patroni, Cracker for NATS
Same company, same bar, same discipline — evidence before action, guardrails on anything destructive, an audit trail after. Concord proved the pattern on Patroni PostgreSQL; Cracker applies it to NATS. Neither is a tech-stack pitch — both exist to make one operator job trustworthy.
