PulseLab is two tools in one: capture webhooks server-side, test WebSockets client-side — both with the real-time visibility you need.
Webhook endpoints
Create capture URLs and inspect every request.
Inspecting requests
Headers, body, query, replay, cURL.
Forwarding
Mirror captures to your local dev server.
WebSocket connections
URLs, subprotocols, headers, statuses.
Messages
Send, receive, inspect frames.
Templates
Reusable message snippets.
