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. 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.
