A RequestBin Alternative: Free Webhook Inspector, No Signup
The original free RequestBin is gone. Webhook Bin is a free alternative — an instant URL, real-time request inspection, then forwarding to localhost.
RequestBin was the original "paste a URL, see the request" tool. The free hosted version was discontinued and folded into Pipedream, so the simple no-signup bin people remember now sits behind an account. If that's what sent you here, you want the same thing RequestBin used to be: a free, instant, no-signup request bin.
That's exactly what Webhook Relay's Webhook Bin is — plus a way to forward those requests to your own code.
If your bins feed Pipedream workflows, note that Pipedream Workflows shuts down on March 31, 2027. The Pipedream Workflows migration guide covers moving those workflows to Webhook Relay functions.
TL;DR
- Want the classic free request bin? Webhook Bin gives you an instant URL with no signup.
- Want to inspect every detail? Headers, query params, method and body, in real time.
- Want it to reach your app? Forward to localhost or a private server with the relay agent.
RequestBin vs Webhook Bin
| RequestBin (Pipedream) | Webhook Relay (Webhook Bin) | |
|---|---|---|
| Free, no-signup bin | Account required | Yes |
| Instant URL | Yes | Yes |
| Real-time inspection | Yes | Yes |
| Custom response | Limited | Yes |
| Forward to localhost / private server | No | Yes (relay agent) |
| Transform / fan-out | Via workflows | Native |
| Permanent endpoint | Paid | Yes (free account) |
How to use it
- Open the bin. Go to Webhook Bin — a unique URL is created instantly.
- Send a request. Point any service or a quick
curlat it:
curl -X POST https://your-bin-url \
-H 'Content-Type: application/json' \
-d '{"hello":"world"}'
- Inspect. The request appears immediately with full headers and body.
- (Optional) Forward it. Create a free account, install the agent, and deliver requests to
localhost:8080or any internal service.
Why developers move from a plain bin
A request bin shows you the payload. Webhook Relay also delivers it — so the same URL you debug with becomes the one your provider keeps calling, with retries, transformations and multiple destinations when you need them.
Open Webhook Bin or create a free account to forward requests to your own machine.
