SafeMigrate is public — zero-downtime Postgres migration sandbox

[KhyFee]

What this is

SafeMigrate is a sandbox for safer Postgres migrations: Docker shadow clone, schema diff, rollback SQL.

Looking for feedback

1. What’s your biggest migration scare (locks, data backfill, rollback)?
2. Shadow DB approach — useful for your team size?
3. What should the first “demo path” be in the README?

Q&A open.
