GitHub webhook testing

Test GitHub webhooks on localhost—without exposing a port.

Debug GitHub webhooks (pushes, PRs, issues) without deploying. Point a repo or org webhook at RelayFox and inspect every delivery. RelayFox keeps receiving if your laptop sleeps, so the original delivery is waiting when you reconnect.

No signup. Disposable URL lasts 24 hours.

Listening live

X-Hub-Signature-256: preserved

Forward when ready

npx relayfox forward <id> --to http://localhost:3000

Inspect the original headers and raw body.

Receive events while localhost is offline.

Forward through one free CLI command.

1
Create a free RelayFox URL above (no signup needed).
2
Paste it as your webhook endpoint: Repository → Settings → Webhooks → Add webhook (or Organization settings).
3
Trigger an event (e.g. push) and watch it arrive live in RelayFox.

Run the CLI to forward captured events to your local server:

npx relayfox forward <endpoint-id> --to http://localhost:3000

5
Inspect headers, body and replay any event as many times as you need.

RelayFox preserves the X-Hub-Signature-256 header when forwarding, along with the captured body. Verify against the original raw body. If GitHub includes the public destination URL in its signature, configure your verifier with the RelayFox capture URL rather than the localhost forwarding URL.
