Koalr installs statistics

Every engineering team has experienced it: a deployment goes out Friday afternoon, and by Monday you're rolling back. Post-mortems point to the same causes — low test coverage, a PR that bypassed the right reviewer, a service with a failure history getting another risky change.

Koalr ends that cycle. Install the GitHub App and every pull request gets a risk score from 0–100 before it's merged.

• Connect in minutes

Install the GitHub App to your organization. Koalr requests only the permissions it needs: read access to pull requests, commits, and repository metadata, plus write access to post Check Runs on PRs. No source code is read. No secrets are accessed.

• Every PR gets scored automatically

When a pull request is opened or updated, Koalr calculates a risk score using 36 research-validated signals spanning code complexity, testing coverage, team process adherence, and infrastructure health. The score and a full signal breakdown appear as a GitHub Check Run directly on the PR — no dashboard to open, no context switching.

• Block high-risk deploys with GitHub Check Runs

Set a risk threshold in your Koalr settings. PRs above that threshold automatically fail the Check Run, blocking merge until risk is addressed. Teams using this as a required status check report a significant reduction in production incidents within the first quarter.
