See how Webhook.site lets developers test and debug webhooks and HTTP requests for free, plus its Pro and Enterprise pricing and open-source self-hosted option.
Webhook.site is a lightweight developer tool that gives you an instant, disposable URL and email address for capturing and inspecting incoming HTTP requests, webhooks, and emails.
It was built by developer Simon Fredsted and is offered both as a hosted cloud service at webhook.site and as an open-source, MIT-licensed project that can be self-hosted with Docker.
Developers use it as a fast alternative to spinning up a local server or tunneling tool whenever they need to see exactly what an external service, such as a payment processor or a source-control platform, sends in a webhook payload.
The core feature is the live request inspector, which shows full headers, body content, query parameters, and timing for every request or email sent to a generated URL or address, updating in real time in the browser.
Custom response configuration lets a URL act as a mock API endpoint, returning a chosen status code, headers, and body, which is useful for testing how another system handles different responses.
The Pro-tier Custom Actions feature adds scripting so incoming requests can be transformed, forwarded, or reacted to programmatically, moving Webhook.site beyond pure inspection into lightweight webhook processing.
Webhook.site is free to use for quick testing, with each free URL limited to 50 stored requests and automatic data deletion after 7 days.
The Pro plan costs 27 dollars per month or 270 dollars per year and raises limits to up to 50 custom URLs, unlimited requests with a 10,000-request history, Custom Actions, CSV export, and URLs that no longer expire.
The Enterprise plan costs 69 dollars per month or 699 dollars per year and adds unlimited URLs and schedules, a 100,000-request history, custom domain support, SAML SSO, multi-user support, and priority support.
It is used to instantly capture and inspect incoming HTTP requests, webhooks, and emails, most often while integrating with or debugging a third-party API.
Yes, the core inspection feature is free, with a limit of 50 stored requests per URL and 7-day data retention on the free plan.
On the free plan, URLs and their captured data are automatically deleted after 7 days; paid plans offer URLs that do not expire.
Yes, an open-source, MIT-licensed version is available on GitHub and can be self-hosted using Docker.
The hosted free and Pro tiers are intended for testing rather than sensitive production data; teams with strict data requirements often use the self-hosted open-source version instead.
Pro raises request limits, adds Custom Actions scripting, CSV export, and URLs that never expire, for 27 dollars per month.
Common alternatives include Beeceptor and Hookdeck, which offer similar request inspection and, in some cases, production-grade webhook delivery features.
Custom domain support for URLs and emails is available on the Enterprise plan.
