How it works

🔗
Connect your repo
Install our GitHub App (read-only). We fetch your Gemfile.lock. Your source code is never read or stored.
🔍
We scan continuously
Every gem is checked against RubyGems, ruby-advisory-db, and Rails release history. You get a score, not a wall of text.
⬆️
We open the PR
When gems need updating, we open the pull request with a clear description. You review, CI runs, you merge. Done.

Common questions

What does "we open the PR" mean exactly?
We create a real GitHub pull request in your repo with updated gem versions, a plain-English summary of what changed, and links to CVEs or release notes. Your CI runs. You merge.
Do you read my source code?
No. We connect via GitHub App and only fetch your Gemfile.lock — a plain-text list of your gem versions. Your application code is never accessed or stored.
What counts as "one app"?
One GitHub repository with one Gemfile.lock. Multi-app monorepos can be added as separate entries on Team.
How does the free trial work?
You get 14 days free. No credit card required to start. At day 14, billing begins automatically unless you cancel.
Can I upgrade from Solo to Team?
Yes, any time. The difference is prorated. You won't lose any monitoring history or configuration.
What if I need more than 5 apps?
Email us at hello@keepalive.polsia.app and we'll set up a custom plan.
