Hookbin alternatives (hookbin.com is gone)

If a blog post, README, or Stack Overflow answer told you to "create a Hookbin" and you just discovered that hookbin.com silently redirects to Pipedream's RequestBin: you're not imagining it. The standalone Hookbin — the simple "here's a URL, send anything at it, inspect what arrived" tool — no longer exists as its own product. It joined the same graveyard as the original requestb.in, PostBin, and half a dozen other free request inspectors that developers relied on.

Where hookbin.com points now

The domain 301-redirects to pipedream.com/requestbin. Pipedream is a workflow-automation platform: you can inspect requests there, but only by creating an account and working inside their builder. It's a fine platform — but it's an on-ramp to a much bigger product, not the two-second throwaway bin Hookbin was. The RequestBin story is the same one.

What Hookbin actually gave you

An instant URL, no signup, that captured any HTTP request — method, headers, query string, body — and showed it to you in a clean UI. That's the bar an alternative has to meet. Current options:

1. CatchHook (this site)

$ curl https://catchhook.catchhook.workers.dev/new        # instant bin, no signup — or click the button below

• Same instant-bin flow Hookbin had: one click or one curl, no account, start capturing immediately. Anonymous bins live 24 h; a free account extends that to 1,000 requests per bin and 30-day retention.
• Inspect everything — headers, query, form fields decoded, JSON pretty-printed, binary bodies preserved byte-exact with a hex view.
• Beyond inspection: replay any capture to your real endpoint, copy it as curl / fetch / Python / HTTPie, ✓/✗ HMAC signature badges (GitHub, Stripe, Shopify, generic), diff two captures, configurable responses (status/headers/body/delay), custom URLs like /h/my-stripe-dev, JSON + HAR export, and a CLI with live tail and relay-to-localhost.
• No paid tier exists — nothing above is a teaser for a paywall.

Trade-offs, honestly: live view is polling-based (captures appear within a couple of seconds), and it's hosted-only — if payloads can't leave your network, self-host something instead.

2. webhook.site

Good: mature and well known; instant URL with no signup.
Trade-offs: free tier is roughly 100 requests per URL with short expiry, and the features you want mid-debug — replay/forwarding, custom URLs, CLI, retention — are paid. Full comparison.

3. Pipedream RequestBin

Good: actively maintained, powerful if you'll use the workflows.
Trade-offs: account required, and inspection lives inside the workflow builder — heavier than a throwaway bin.

4. Self-hosting

Good: data never leaves your infra.
Trade-offs: you now run a service in order to debug a service. Right call for regulated environments, slow path for "I need to see this payload right now".

Quick chooser

• The Hookbin experience, still free → CatchHook.
• You'll actually build Pipedream workflows → their RequestBin is fine.
• Payloads must stay in-house → self-host.
