Webhook.site
Free online webhook tester and HTTP inspector that captures, inspects, and debugs requests in real time without setting up a local server. Also generates unique test email addresses and DNS names.
Use Cases
Free Tier
Anonymous URLs: 50 requests max, expires in 7 days. Free account: endless requests, keep URL forever, run workflows on every hit.
How to Maximize the Free Tier
The anonymous URL you get on first visit is capped at 50 requests and dies after 7 days — treat it as a throwaway for one-off tests. Sign up for a free account to unlock endless requests and a permanent URL; this is the tier that makes Webhook.site genuinely useful for a dev loop. The free account also lets you run simple workflows on incoming requests and replay them later, so you can debug Stripe/Slack/GitHub webhooks without spinning up a server. Watch the 50-request cap on anonymous URLs during active integration testing — you'll hit it fast with retries. Keep payloads small; there's no stated unlimited storage, so old requests get cleaned out. Combine with ngrok (already in the directory) when you need to inspect requests that must reach a live tunnel, and pair with Hoppscotch for hand-crafted test requests.
Getting Started
Open webhook.site in your browser → a unique URL is generated instantly → copy it and use it as the endpoint in your webhook or API config → trigger the request from your app → watch headers, query strings, and body appear in real time. For a permanent URL: sign up (free) → associate the URL with your account → it no longer expires. Use the Docs tab for advanced features like custom responses and workflows.
Pros
- Zero setup: Instant unique URL on first visit — no account, no config, no install
- Real-time inspection: Full headers, query strings, and body shown live in the browser with syntax highlighting
- Free account is genuinely free: Endless requests and permanent URLs at $0 — unusual for webhook testing tools
Cons
- Anonymous URL limits: 50-request cap and 7-day expiry on the no-account URL can break longer test sessions
- Public by default: Anyone with the URL can view captured requests — never send secrets or production tokens
- No stated storage limit: Free-tier retention is undefined; old requests can be cleaned out without warning
