Free Webhook Testing Tools Compared (2026): webhook.site, Beeceptor, RequestBin, Hookdeck Console, ngrok Inspector and Webhook Bin
The free tools for testing and inspecting webhooks in 2026, compared: webhook.site, Beeceptor, RequestBin, Hookdeck Console, ngrok's inspector, provider CLIs and Webhook Bin — what each shows you and when to use it.
A webhook tester gives you a URL that records whatever is sent to it, so you can see exactly what a provider posts before you write a line of handler code. The free options in 2026 differ in what they show, how long they keep it, whether they can answer the sender with a custom response, and whether they can get the request to your localhost afterwards. Here is what each one is good for.
TL;DR
| Tool | Signup | Keeps history | Custom response | Signature check | Replay to localhost | Sample payloads |
|---|---|---|---|---|---|---|
| Webhook Bin | No | Yes | Yes (status, body, headers, delay, failures) | Yes, built in | Yes | Yes (Stripe, GitHub, Shopify, more) |
| webhook.site | No | Limited on free | Yes | No | No | No |
| Beeceptor | No for basics | Limited on free | Yes, rules | No | No | No |
| RequestBin (Pipedream) | Yes | Yes | Via workflow | No | No | No |
| Hookdeck Console | Yes | Yes | No | No | Yes (CLI) | No |
| ngrok inspector | Yes | Session | No | No | Is localhost | No |
| Provider CLIs (Stripe, GitHub) | Provider account | No | No | Yes (Stripe) | Is localhost | Yes (triggers) |
Free-tier details reflect public documentation in September 2026 and change often.
Webhook Bin: capture, mock, verify, replay, no signup
Open Webhook Bin and you have a URL. Every request to it appears live with method, headers, query and body, parsed JSON, and a copy-as-curl or code snippet. Configure what the bin answers with, including failure rates and delays, to test how a sender behaves. Verify the HMAC signature against your secret in place. Send a realistic Stripe, GitHub or Shopify sample to your own endpoint. When the payload looks right, replay it to localhost through the relay agent or transform it with a function. Everything runs against a public API too, so scripts and AI agents can use it (reference).
Verdict: the most complete free tester, and the only one with a path from "look at the payload" to "deliver it somewhere".
webhook.site: the quickest look
Open the page, copy the unique URL, and read requests as they arrive. Custom responses and some scripting are available; longer history and permanent URLs are paid.
Verdict: fine for a one-off look. See webhook.site alternative for the limits.
Beeceptor: mock rules
Beeceptor gives you a named endpoint and rule-based mock responses, which makes it good for simulating a third-party API as well as catching webhooks.
Verdict: strongest for mocking APIs; history and rules are limited on the free tier. See Beeceptor alternative.
RequestBin by Pipedream: bins that start workflows
RequestBin is now part of Pipedream: a bin URL whose requests can trigger workflow steps. It requires an account.
Verdict: useful if you will build a Pipedream workflow anyway, but Pipedream Workflows shuts down on March 31, 2027, so check the Pipedream Workflows migration guide before you build anything new on it. See RequestBin alternative.
Hookdeck Console: inspect and forward locally
Hookdeck's console shows events for a source and its CLI forwards them to localhost. It requires an account and is oriented around Hookdeck's connections model.
Verdict: good if you are evaluating Hookdeck; more setup than a bin for a quick check.
ngrok inspector: see what hit your tunnel
If you already run ngrok, its local web interface at port 4040 shows every request that came through the tunnel and can replay it.
Verdict: convenient when localhost is already the destination; it is not a place to capture requests before you have a server.
Provider CLIs: Stripe CLI and friends
stripe listen --forward-to localhost:4242/webhook prints each event as it forwards it and can trigger test events. The GitHub CLI has a similar webhook forwarder.
Verdict: best for a single provider during development; no capture, no history, one provider at a time.
Which one when
- First look at a payload: Webhook Bin or webhook.site.
- Simulate a flaky or slow receiver: Webhook Bin response settings or Beeceptor rules.
- Check a signature: Webhook Bin, or the HMAC verifier.
- Get the request to your laptop: Webhook Bin replay, Stripe CLI, or a Webhook Relay forward.
- Keep testing across a team over weeks: a Webhook Relay bucket with a permanent URL and logs.
