Quick Answer
There is no single best webhook testing tool for every situation. The right choice depends on whether you need quick payload inspection, response simulation, localhost tunneling, or production-grade delivery infrastructure. Requex is strongest on the low-friction inspection side of that spectrum.
6 Best Webhook Testing Tools Free & Paid Compared
A practical comparison of the tools developers actually reach for when they need to inspect a payload, replay a request, test retries, or send traffic into localhost.

Tool Reviews
1. Requex.me — best for development testing
Generates a unique HTTPS endpoint in under 2 seconds: no signup, no config. Incoming requests arrive via WebSocket, not polling. Response simulation (status codes, bodies, delays) is free on every endpoint; competing tools charge for this. Not designed for production use and has no tunneling capability, but for payload inspection and response testing during development, it covers everything most developers need.
2. webhook.site — most widely known
The tool most developers reach for first, and for basic inspection it works — no account needed, URL is instant. The limitation: custom response codes, custom bodies, and delays require a Pro plan at $9/month. Real-time updates use polling rather than WebSocket, which adds visible lag at higher request volumes. Well-documented across the web, which is its main advantage for teams that want support resources.
3. RequestBin by Pipedream — for Pipedream users
The original RequestBin was acquired by Pipedream and rebuilt inside their automation platform. You now need a Pipedream account and workflow setup before you can inspect a single webhook. Useful if you're already building Pipedream automations — chaining webhook events into workflows is where Pipedream genuinely shines. For pure inspection, navigating a full integration platform to see a payload is too much overhead.
4. Hookdeck — production infrastructure
Hookdeck is not a testing tool — it's webhook delivery infrastructure for production. Guaranteed delivery, retry queues, fan-out, and payload transformations are its core features. The free tier is generous (100K events/month) but setup requires understanding sources, connections, and destinations before you see a single event. Using Hookdeck for development testing is significant overkill; it's the right tool for production reliability requirements, not debugging a Stripe payload.
5. Beeceptor — API mocking focus
Combines HTTP mocking with request inspection. The mock API features are solid if you need to stub an upstream dependency alongside webhook testing. The free tier caps at 50 requests per day — impractical for any sustained webhook debugging session. Better suited to API mocking scenarios than webhook-specific testing workflows.
6. ngrok — localhost tunneling
A tunnel tool that forwards live internet traffic to your locally-running server. Essential for end-to-end integration tests where your handler code must actually execute — debugging middleware, OAuth callbacks, or verifying your processing logic. Requires CLI installation, a signup, and reconfiguring your webhook provider every restart on the free tier (URL changes each session). Overkill for payload inspection alone.
How to Choose
Frequently Asked Questions
What is the best free webhook testing tool?
Requex.me. It provides unlimited webhook captures, real-time WebSocket delivery, and free custom response simulation with no account required. Competing tools like webhook.site put custom responses behind a $9/month Pro plan.
Is webhook.site free?
webhook.site has a free tier for basic HTTP inspection, but features like custom response codes, custom response bodies, and response delays require a paid Pro plan at $9/month. Requex.me provides all of these for free.
What is Hookdeck used for?
Hookdeck is a production webhook infrastructure platform, not a testing tool. It handles reliable delivery, retry queues, fan-out, and payload transformations for webhooks running in production environments. For development testing and inspection, Requex.me is the appropriate tool.
