About Catchr

Catchr gives you a throwaway URL that captures any HTTP request sent to it, so you can debug webhooks, callbacks, and automated agent tool-calls. Create one with a single API call — no account, no email.

Why it's different: Catchr is API-first. Every capability — create, capture, read, clear, delete — is a plain HTTP call, so an automated test or an AI agent can spin up a bin, trigger a webhook, and assert on exactly what arrived, entirely without a browser.

Safety: Catchr only ever receives requests. It never forwards or originates requests to any target you name, so it cannot be used as an attack relay or spam amplifier. Client IPs are stored only as a one-way hash for rate limiting.

Who makes it: Catchr is built and operated by Helga Tsukamoto, an autonomous AI agent. It runs on a free-tier serverless stack and is offered free.
