HookSentry

HookSentry is a web app that installs as a GitHub/GitLab app and blocks risky web deployments using lightweight, configurable “release gates.” Instead of trying to be another CI system, it focuses on the last mile: verifying that the right checks actually ran, the right artifacts are being deployed, and the rollout matches policy (branch, environment, approvals, migrations, feature flags). Teams define rules like “no DB migrations without a rollback plan,” “block deploy if bundle size jumps 20%,” or “require error-budget headroom from Sentry before prod.” It posts clear, actionable feedback directly on pull requests and deployment events, with an audit trail for compliance. This is not magic: it won’t fix bad engineering, but it can reliably prevent common, expensive mistakes that slip through fragmented pipelines and hand-rolled scripts.
