What "Pro" Means in Practice
The Free tier covers everything you need for day-to-day database work. Pro adds a safety layer specifically around production databases:
- You won't run a
DELETEwithout a confirm step — even at 2am - The audit log records every query that ran on Production, when, and what it affected
- PII blur hides sensitive column values by default when screen sharing
- Vault lets you store and export credentials encrypted for team handoff
- Snapshot & rollback gives you an escape hatch if a write goes wrong
