Tool Reviews
1. Requex.me
Best overall for development testingRequex.me is the strongest option for developers who need to inspect webhook payloads quickly. You get a unique HTTPS URL in under 2 seconds — no signup, no configuration. Incoming requests appear in real-time via WebSocket, not polling.
The response simulation features — custom status codes, response bodies, headers, and artificial delays — are entirely free. This is the key differentiator: competing tools charge for this capability.
Pros
- • No signup required
- • WebSocket real-time updates
- • Custom responses free
- • Unlimited captures
- • Forwarding rules included
Cons
- • Not designed for production use
- • No local tunnel functionality
2. webhook.site
Best for quick one-off inspectionswebhook.site is the most widely known tool in this category. It requires no signup for basic use and generates a URL quickly. The interface is familiar to most developers.
The limitation: custom response codes, custom bodies, and response delays are locked behind a Pro plan at $9/month. Real-time updates use polling rather than WebSocket, which adds visible lag at higher request volumes.
Pros
- • No signup for basic use
- • Well-known, widely documented
- • Supports scripting (Pro)
Cons
- • Custom responses require Pro ($9/mo)
- • Polling-based updates (not WebSocket)
- • Free tier has request limits
3. RequestBin by Pipedream
Good if you're already in the Pipedream ecosystemThe original RequestBin (now Pipedream's HTTP triggers) requires a Pipedream account. Powerful if you need to chain webhook events into automations, but overkill for inspection alone.
The original no-friction experience — generate a URL instantly, no account — no longer exists. You now navigate a full workflow platform just to see a payload.
Pros
- • Integrates with Pipedream automations
- • Familiar brand name
Cons
- • Account required
- • Complex for simple inspection tasks
- • Rate limits on free tier
4. Hookdeck
Best for production webhook infrastructureHookdeck is not really a testing tool — it's webhook delivery infrastructure for production. Free tier is generous (100K events/month) but setup requires understanding sources, connections, and destinations.
Using Hookdeck for development testing is like using a load balancer to serve a static file. The capability is there, but it's the wrong tool for the job.
Pros
- • Guaranteed delivery in production
- • Fan-out and routing
- • Payload transformations
Cons
- • Account and configuration required
- • Complex setup for simple inspection
- • $100+/mo at scale
5. Beeceptor
Good for mock APIs alongside webhooksBeeceptor combines HTTP mocking and request inspection. It's useful if you need to build a mock API server alongside your webhook testing workflow.
The free tier is very limited at 50 requests per day — not practical for any sustained webhook testing. Better suited for API mocking than webhook-specific testing.
Pros
- • Good API mocking features
- • No signup for basic use
- • Custom responses included
Cons
- • 50 req/day free limit is very restrictive
- • Not webhook-testing focused
6. ngrok
Best for forwarding webhooks to your local serverngrok is a tunnel tool, not a testing tool. It's essential when you need live traffic forwarded to your running server code — for end-to-end integration testing where your handler logic must execute.
ngrok now requires signup even for basic use. On the free tier, your URL changes every time you restart the tunnel, meaning you must reconfigure your webhook provider each session.
Pros
- • Live traffic to your local server
- • Works with any local service
- • Persistent URLs on paid plans
Cons
- • Requires signup and CLI install
- • URL changes on restart (free tier)
- • Overkill for payload inspection only
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.
