CatchKit is an all-in-one development platform that lets you catch webhooks, collect form submissions, and create or send email templates—all without writing backend code. Designed for developers and product teams, CatchKit simplifies integration and automation, allowing you to focus on building workflows instead of managing infrastructure. It supports web apps, SaaS platforms, and other environments, providing a flexible alternative to tools like IFTTT, Zapier, Make.com and n8n.





Hey Hi
Just went live with CatchKit (catchkit.online) — a platform that combines webhook debugging, form backends, and email
template testing into one tool.
Why I built it:
Looked at the market and saw:
- Formspree: ~$18K MRR with 3 employees (form backends)
- Webhook.site: ~$20K MRR, solo founder (webhook debugging)
- Mailtrap: Millions in revenue (email testing)
All three catch HTTP requests. Same infrastructure, different branding. I figured — why not combine them?
The bet:
Most devs who need webhook debugging also have forms on their sites and also need to test emails. Sell them one tool instead
of three at $9/mo individual or $14/mo combined.
Stack: FastAPI + MongoDB (infra cost: ~$15/mo)
Margins: 95%+
Target: $5K MRR → Flippa exit at 3-5x annual profit
Just launched, zero revenue, looking for first users and
brutally honest feedback.
