Pulse Request Runner

Pulse Request Runner is a local-first API client built for developers who debug from Chrome DevTools. Copy any request from the Chrome Network tab as cURL, paste it into Pulse, and instantly turn it into an editable request. Update the URL, method, headers, auth, query params, body, variables, and execution settings, then rerun it locally from your browser. Pulse helps you move from “what happened in the browser?” to “let me test this exact request again” without moving sensitive request data into a hosted workspace. Features: 1. Import Chrome DevTools “Copy as cURL” 2. Edit method, URL, params, headers, auth, and body 3. Support for JSON, GraphQL, form URL encoded, multipart fields, gRPC-Web inspection, WebSocket, and SSE 4. Local collections and environments 5. Variables with {{name}} syntax 6. Response body, headers, timing, JSON paths, and diff views 7. Generate and run saved validation tests 8. Export collections, shell scripts, and CI-ready config 9. Right-click menu for copied cURL and auth/cookie helpers 10. Local-first storage with no Pulse cloud account Pulse is designed for API debugging, browser request replay, and fast local validation. Your collections and request data stay in your browser unless you explicitly export them.
