Webhooks require a publicly accessible URL to receive data. During development, localhost isn't accessible. Developers use ngrok tunnels, but they're unstable and expire. Inspecting webhook payloads requires logging and manual parsing.
Generate a unique URL endpoint. Any HTTP request sent to it is captured, displayed in a real-time dashboard with headers, body, and timing. Replay requests to your localhost for testing.
Backend developers integrating with third-party APIs (Stripe, GitHub, Twilio) who need to inspect webhook payloads during development
API-first architecture means every SaaS sends webhooks. Microservices multiply the number of webhook integrations. Developer experience tools are a fast-growing market with high willingness to pay.
Freemium: Free (100 requests/day, 24h retention), $9/mo Pro (unlimited, 30-day retention, replay), $29/mo Team (shared endpoints, API).
