Webhook infrastructure for builders

Stop rebuildingwebhook plumbing.

FixedHook gives every project a permanent webhook URL, a live inspector, replay tools, and a CLI tunnel that makes local and production debugging feel like one workflow.

Live debugging surface

A webhook inspector built like a control room.

No generic table dump. FixedHook presents events as a stream with payload context, response metadata, replay state, and the exact command to connect your tunnel.

Workflow

One URL from first test to production traffic.

FixedHook removes the loop of changing webhook URLs, restarting tunnels, losing events, and manually replaying failed deliveries.

Point providers once

Choose delivery target

Run fixedhook up for local delivery, or set a deployed webhook URL for staging or production. The provider URL stays unchanged.

Inspect and replay

Watch the live event feed, open payloads, share failures, and replay events with one click.

Capabilities

Everything you need when a webhook breaks.

A focused toolkit for developers debugging third-party integrations under real pressure.

Stable webhook aliases

Use one provider-facing URL forever. Move between laptops, preview apps, and production targets without changing provider settings.

Event stream, not tables

Scan incoming webhooks by provider, route, response, latency, attempts, and payload size in one high-signal feed.

Replay with context

Re-deliver original payloads and headers to your active tunnel, then inspect each replay attempt and response body.

Secure by default

Signature verification, request metadata, scoped share links, and clean audit trails for sensitive integration debugging.

Project config workflow

Define aliases and local ports in webhooks.yaml, commit it with the repo, and run named tunnels without remembering flags.

Delivery settings

Keep providers pointed at one FixedHook URL, then switch delivery between your local CLI tunnel and a deployed HTTPS webhook endpoint.

Shareable debug links

Send a single event to a teammate or customer so they can inspect payloads without exposing your full dashboard.

Pricing

Start free. Scale when the traffic matters.

Simple limits, no per-seat tax, and enough history to debug what actually happened.
