Hooklistener is answering right now. Last checked 12 min ago. Last commit 26 Sep 2026.
Webhook, email, WebSocket and tunnel testing for AI agents: capture, wait, verify, replay.
Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.
