Overview
Product summary
Review the store description, core capabilities, and common use cases.
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

Good idea and really appreciate the local first storage
Makes API debugging much faster by letting me capture, edit, and replay requests directly from DevTools. Clean, lightweight, and saves a lot of context switching compared to opening Postman for quick tests.
