Beeceptor alternatives for webhook inspection

Beeceptor is a solid product — but it's an API mocking tool first, and its free tier reflects that: roughly 50 requests per endpoint per day, public endpoints, and history measured in hours-to-days. If what you actually need is to inspect webhooks — see exactly what GitHub / Stripe / Shopify / your own service sent, replay it, verify signatures — you hit those limits fast, and you're paying for mocking machinery you don't use.

First: what are you actually doing?

• Mocking an API (your frontend needs a fake backend with rules, templated responses, CRUD routes) → Beeceptor is genuinely good at this, and self-hosted tools like Mockoon or WireMock are strong free options. CatchHook is not a mock server — it won't route /users/:id differently from /orders.
• Inspecting requests / debugging webhooks (a URL you point things at to see what arrives) → that's the job below, and where the free-tier math matters.

The free-tier math for webhook debugging

A single misbehaving webhook integration retries. Stripe retries for days; a busy repo's GitHub webhooks fire on every push, comment, and check run. 50 requests/day disappears in one debugging session — usually right before the request you actually needed to see.

CatchHook (this site)

$ curl https://catchhook.catchhook.workers.dev/new        # instant bin, no signup

• 1,000 requests per bin — not per day, per bin — and 30-day retention with a free account (anonymous bins: 24 h). No paid tier exists.
• Built for webhooks: HMAC signature badges (GitHub, Stripe, Shopify, generic) show ✓/✗ per capture before you've written any verification code.
• Replay any capture to your real endpoint byte-exact, or copy it as curl / fetch / Python / HTTPie.
• Configurable responses — status, headers, body, delay — including templates like {{body.challenge}}, so Slack/Zoom URL-verification handshakes pass. (This covers the most common "mock" need in webhook work.)
• CLI with live tail and a relay mode that re-delivers webhooks to localhost without a tunnel.
• Custom URLs free (/h/my-stripe-dev), JSON + HAR export, read-only share links per capture.

Trade-offs, honestly: no path-based routing or mock rule engine — if you need "GET /api/users returns this list, POST returns 201", use a real mock server. Live view is polling-based (~2 s), and bins are hosted-only.

Other options

• webhook.site — well known; free tier is ~100 requests with short expiry, and replay/forwarding, custom URLs, and the CLI are paid. Full comparison.
• Mockoon / WireMock (self-hosted) — excellent for mocking, free forever, but they run on your machine: no public URL for real webhook providers to reach without a tunnel.
• Pipedream RequestBin — request inspection exists, but only inside their workflow platform. More on the RequestBin situation.

Quick chooser

• Mock API with routing rules → Beeceptor or Mockoon.
• Inspect / replay / verify webhooks, generous free limits → CatchHook.
• Payloads can't leave your network → self-host (Mockoon, WireMock, or a RequestBin fork).
