Hooklistener is a webhook debugger that captures every request to an HTTPS endpoint so you can inspect payloads, troubleshoot silent failures, and replay requests to any environment. Your coding agent can do the same over MCP. Fix broken integrations before they hit production. Just need to send a test event? Try our webhook tester tool.
Step 1 · Incoming webhook
Step 2 · Stored & inspected
The payload is preserved based on your plan's retention window, signature-checked, and streamed into the live inspector so you can replay or diff it later.

Hooklistener is the only tool that combines capture, debugging, and replay in a free tier.
Move from one-off bins to a production-grade webhook platform with replay, forwarding, and monitoring built in. Compare features side-by-side and migrate in minutes.
Persist webhook history for 14+ days, search instantly, and replay to any environment.
Send events to QA, staging, and production with conditional routing and transformations.
Invite collaborators, mask secrets, and stay audit-ready—no public bins or shared tokens.
Can Hooklistener replay captured payloads?
Yes. Every webhook stays in your history so you can replay to any environment, diff responses, and attach notes for your team.
How does Hooklistener stack up to webhook.site?
Webhook.site gives 7-day anonymous retention but no replay, no forwarding, and no sharing. Hooklistener adds permanent URLs, replay, MCP editor integration, shared inspection links, and up to 60-day retention on the Team plan.
Is there a cost to start debugging?
No. The free plan includes debugging tools and a secure HTTPS endpoint. Upgrade to Pro for 14-day retention and advanced features.

Forward webhooks to your local environment or analyze them directly in Hooklistener.
Schedule webhooks and receive alerts to ensure everything runs smoothly.
A repeatable process for diagnosing and fixing webhook issues — whether you're dealing with a silent failure, a signature error, or a schema change from a third-party provider.
Point your webhook source at a HookListener endpoint. The next delivery lands in your history with full headers, body, status code, and latency — no guesswork about what was actually sent.
Open the request and check the JSON body against the schema you expect. Mismatched field names, wrong types, or missing nested keys show up immediately with syntax highlighting.
Check the raw headers tab for HMAC signatures (e.g. X-Hub-Signature-256, Stripe-Signature) and compare against your secret. A signature mismatch here means the payload was altered in transit or the wrong secret is configured.
Once you've identified the issue, hit Replay to forward the exact original request to your localhost URL. No need to retrigger the source event — iterate on your handler until the response is correct.
After deploying a fix, replay the same payload to production and compare the response side-by-side. Confirm the status code changed from 500 to 200 before closing the incident.
Hooklistener is a webhook debugger for developers and their AI coding agents. A Debug Endpoint captures every incoming request with headers, body, query, IP, and TLS details so you can inspect it live, replay it to any environment, and share a read-only link with a teammate. An MCP server lets Claude Code, Cursor, or Codex do the same work from the terminal, Monitors alert you when webhooks stop arriving, Email Inboxes turn email into webhooks, and the CLI tunnels live traffic to localhost.
Yes. The Free plan includes one Debug Endpoint with one day of request history, one Email Inbox, one Monitor, and full MCP server access, with no credit card required. You can also use the anonymous debugger on this page without signing up. Try Hooklistener for free or compare plans.
Yes. Hooklistener ships an MCP server with 46 tools, so Claude Code, Cursor, or Codex can create endpoints, wait for the next webhook, read the captured payload, replay it, and diagnose why your handler failed, all from the terminal. Set up the MCP server.
Hooklistener, ngrok, Webhook.site, and RequestBin all capture webhook payloads. Hooklistener uniquely offers payload replay and SMS-specific header parsing.
Use Hooklistener to capture the Twilio payload, then replay it to your localhost URL or forward it live with the CLI tunnel. You can inspect the X-Twilio-Signature header and verify HMAC integrity. Twilio webhook debugging guide.
Yes. Hooklistener generates a free public HTTPS URL that captures any request, letting you test without deploying. Custom responses let the endpoint return the status, headers, body, and latency you choose, so you can exercise retry logic on purpose.
The Free plan covers sporadic debugging and personal projects. Pro adds unlimited requests, 10 endpoints, 14-day retention, and the CLI tunnel for day-to-day integration work. Team adds 60-day retention, shared workspaces, and role-based access for groups that debug the same integrations together. See pricing.
