SQL Simulator
Builds small, realistic test databases from your existing schema, without copying every table in full.
SQL Simulator is in active beta — expect ongoing fixes and improvements as we refine it.
If you need data governance protections — limits on how much sensitive data can be retrieved, specific records blocked unless approved, or a full audit trail of who accessed what — that's what 00DB provides. SQL Simulator doesn't have those controls, so it's built for test/development databases that don't contain sensitive data, not as a replacement for them.
Free for personal and education use. No signup, no key, no credit card.
- ✓ Connect a single data source, upload the migration or schema-change scripts you want to test, and build a sandbox to run them against
- ✓ Automatically includes dependencies no matter how many steps away they are — a procedure that calls another procedure, which calls a view, and so on
- ✓ Understands SELECT, DELETE, UPDATE, GRANT, and other statement types in your uploaded scripts
- ✓ Ready-to-run docker-compose.yml, nothing to edit
- ✓ Free forever for personal or education use
Personal use only — not for evaluating or running SQL Simulator on behalf of a company. If that's you, see pricing instead.
