GitHub webhook tester
See every GitHub webhook as GitHub sees it.
Paste the URL into Repo Settings → Webhooks. Push, open a PR, label an issue — every payload lands here with the right X-GitHub-Event header.
Skip the GitHub Actions echo trick
No more bouncing payloads through Actions to read them. The full request lands here with one click.
Debug HMAC signatures
See the `X-Hub-Signature-256` header next to the raw body so signature mismatches are obvious.
Replay across all event types
`push`, `pull_request`, `issues`, `release` — capture any event and replay it into local code with the right shape.
