aslam/rails-preflight

Answers one question about a Rails app: what stands between it and Rails X? Scans the lockfile, Ruby version, Dockerfile, schema, config and code, then writes a single HTML report of blockers, fixes, and a suggested upgrade path — one step per Rails minor version. Read-only, offline, deterministic.
