RollbackKit

RollbackKit is a web app + CLI that automatically validates whether your database migrations are truly reversible and safe under real data. It spins up ephemeral clones of your schema and a sampled dataset, replays your migration chain forward and backward, and flags irreversible operations (data drops, unsafe type casts, lock-heavy DDL, missing down scripts). It then generates a “rollback plan” artifact: exact steps, expected runtime, lock impact, and required pre-backups—ready to attach to a pull request. This is not a magic button: it won’t fix bad migrations for you, and it can’t guarantee zero downtime. What it does is catch the common, expensive failures before they hit production, and it makes teams document rollback procedures consistently. It supports Postgres and MySQL first, with CI integrations for GitHub Actions and GitLab CI.
