Know Before
You Migrate.
The open-source database migration analyzer. Catch breaking changes, predict lock times, and deploy with confidence.
go install github.com/iamsr/tapa/cmd/tapa@latestSee How It Works
One command. Complete analysis. Zero surprises.
Powerful Capabilities
Everything you need to analyze, predict, and safely deploy database schema changes without fear.
Lock Analysis
Instantly detect ACCESS EXCLUSIVE locks that would block all reads and writes. Know exactly which tables will be locked, for how long, and how many active queries will be affected. Prevent surprise outages during deployments.
Risk Scoring
Every migration gets a 0-100 risk score based on table size, lock type, backward compatibility, and estimated execution time. High-risk migrations are flagged immediately.
Time Estimates
Predicts exactly how long your migration will take. Accounts for table size, indexes, active connections, and your specific hardware. No more "5 second" migrations taking 5 hours.
CI/CD Integration
Automatically block dangerous migrations in pull requests. Integrates with GitHub Actions, GitLab CI, CircleCI, and all major CI platforms. Get detailed reports as PR comments.
Backward Compatibility
Ensures your running application code still works with the new schema. Critical for zero-downtime deployments and rolling updates. Catches breaking changes before they break production.
Multi-Database
Works with PostgreSQL, MySQL, MariaDB, and more. One unified tool for all your databases. Same analysis, same reports, same safety.
