the Gemfile's ruby directive, every Dockerfile's
FROM ruby:X.Y, and every GitHub Actions workflow's ruby-version:.
- Free, no key needed: checks
.ruby-versionagainst theGemfile'srubydirective. Source at https://github.com/growaleaf/rubydrift-ci. - Pro ($9, one time): also scans every Dockerfile and GitHub Actions workflow and cross-checks every source against every other source. Offline-checked license key — no subscription, no per-seat pricing, no recurring charge, no telemetry.
