We ran Keepalive's health scanner against 8 of the most popular open source Rails applications. Here's what we found.
Keepalive continuously monitors your Rails app's maintenance health โ gems, CVEs, upgrade paths โ and tells you exactly what to fix first.
โ You're in. We'll reach out when Keepalive opens up.
Keepalive fetches the public Gemfile.lock from each repository and runs its Rails health scanner:
checking the locked Rails and Ruby versions against the latest stable releases, counting outdated gems,
cross-referencing the lockfile against known CVEs, and computing a maintenance score.
This report was generated on 2026-05-25. Rails latest stable: 8.1.3.
