Live capture & inspector
Record XHR/fetch in real time. Inspect headers, payload, and response body like the Network tab.
Chrome DevTools Extension · v1.5
Record XHR/fetch, export Postman + cURL ZIP, spot slow APIs, optional PII audit & AI analysis — all without leaving DevTools.
Built for frontend engineers, QA, and security-minded teams debugging SPAs.
Record XHR/fetch in real time. Inspect headers, payload, and response body like the Network tab.
Download a ZIP with Postman collection v2.1, environment variables, and per-request cURL files.
Slow API detection (>5s) with SLOW badges and Excel-ready CSV reports in the export bundle.
Heuristic scan for email, phone, SSN, and more. Masked samples only — off by default.
OpenAI or Gemini with local key storage. PII redacted before sending to the provider.
View and edit localStorage & sessionStorage for the inspected tab. Inline edit, add, delete.
Three steps from capture to handoff.
Right-click any page → Inspect. Find the Requstrix tab alongside Network and Console.
Hit Start and browse your app. XHR/fetch calls appear live with method, status, and duration.
Export Postman + cURL bundle, run optional AI analysis, or hand off to QA with performance & PII reports.
One click on Download All Curls gives your team everything needed to replay and review API traffic.
.curl files per requestrequests/Your traffic stays on your machine.
OpenAI and Gemini API keys are stored in your browser. Never sent to a Requstrix server — there isn't one.
100% client-side capture and export. Your API traffic never leaves your machine unless you export or run AI analysis.
You must explicitly enable PII scanning. Findings show masked samples only — heuristic detection, not legal advice.
XHR and fetch API calls from the inspected tab. It does not capture page navigations or WebSocket traffic.
Download the ZIP, import the collection JSON, then the environment file. Use environment variables for secrets — the export strips them from the collection automatically.
No. PII scan is opt-in only. You must check the "PII scan" checkbox to enable detection. All samples in the UI and reports are masked.
OpenAI (GPT-4o, GPT-4o-mini) and Google Gemini. Choose your provider, save your API key locally, and run batch analysis on captured traffic.
Any request with a response time over 5 seconds gets a SLOW badge and appears in the slow APIs CSV report.
Requstrix is free and 100% client-side — no backend, no tracking, no paywall. If it saved you time today, a coffee keeps new features brewing.
Capture APIs, inspect, export to Postman/cURL, spot slow endpoints and PII exposure — without rebuilding requests by hand.
