PRGuard

PRGuard is a web app (with a GitHub/GitLab app) that blocks pull requests likely to cause outages, security regressions, or runaway cloud spend. It runs lightweight, policy-based checks (dependency risk, secret scanning, permission changes, Terraform blast radius, flaky test patterns) and produces a single “merge risk” score with clear, actionable fixes. The twist: it focuses on the boring, expensive failures teams actually pay for—misconfigured infra, over-permissive IAM, and accidental data exposure—rather than generic style linting. It supports per-repo rules, environment-aware thresholds (stricter for prod), and audit trails for compliance. This is a combination traditional + AI app: deterministic scanners for hard rules, plus an AI layer that summarizes risk, explains impact in plain language, and suggests minimal diffs. It’s realistic because it can start narrow (Terraform + secrets + IAM) and expand as customers demand.
