django-safe-migrations is a Django library that statically analyzes your migrations to catch issues before deployment.

v0.4.0 adds:

- Custom rule plugin system for project-specific checks - 8 new rules covering null=False without backfill, UNIQUE constraints, SQL injection, missing indexes, and more - Configuration validation with typo suggestions - SARIF output for GitHub Code Scanning integration

It's helped us catch several potential outages in CI before they hit production. Happy to answer questions about the implementation.
