What is catchkit?

CatchKit is a unified developer platform that combines three essential tools into one:

Webhooks — Generate unique endpoint URLs to catch, inspect, and debug incoming webhooks from services like Stripe, Shopify, GitHub, and more. Replay failed deliveries, forward to localhost, and view payloads in real time.

Forms — Point any HTML form at a CatchKit endpoint and instantly collect submissions without writing backend code. Get email notifications, query submissions via REST API, and export data. Perfect for static sites built with Next.js, Astro, Hugo, and other JAMstack frameworks.

Email Templates — Preview and test your transactional email templates before sending them to real users. Catch outgoing emails in a sandbox inbox, inspect HTML rendering, and share previews with your team.

Built for developers, freelancers, and agencies who are tired of paying for three separate tools. CatchKit replaces Webhook.site + Formspree + Mailtrap with a single, affordable platform.

Key features:

  • Real-time payload inspection with JSON viewer
  • REST API to query all captured data
  • Email, Slack, and Discord notifications
  • Spam protection for form submissions
  • File upload support
  • CSV and JSON export
  • Team collaboration
