Koalr App installs statistics

Score every pull request for deployment risk before it's merged. Koalr runs 36 research-validated signals — coverage drops, CODEOWNERS violations, file churn, author experience, deploy timing — and posts a pass/fail Check Run on every PR.

Risk scores appear as native GitHub Check Runs. Set a threshold to automatically block high-risk merges. No workflow changes required.

What Koalr does

Koalr predicts production incidents before they happen by scoring every PR for deployment risk. Install the GitHub App and every pull request gets a pass/fail Check Run with a numeric risk score and a breakdown of what's driving the risk.
