Capture GraphQLIn One Command
Stop wrestling with mitmproxy scripts and certificate configs.
Intercept, analyze, and export GraphQL traffic to Postman in seconds.
npm install -g graphql-grabReverse-engineering GraphQL is a nightmare
Need to capture GraphQL traffic from a mobile app or webapp? Here's what you're dealing with today:
Complex proxy setup
Install mitmproxy, configure SSL certificates, set up browser/device proxy settings, deal with certificate pinning...
Custom Python scripts
Write scripts to filter GraphQL from HTTP noise, parse operations, extract variables. Hope it doesn't break.
Multiple tool chains
mitmproxy → HAR export → converter script → Postman import. Four tools for one job.
Hours of setup time
What should take minutes takes hours. And you have to redo it every time on a new machine.
Before GraphQL Grab
With GraphQL Grab
Built for the gap nobody filled
Apollo, Postman, Insomnia are great for building GraphQL. But nothing existed for capturing it. Until now.
Zero Config
No Python. No certificates. No proxy settings. One npm install and you're capturing traffic.
GraphQL-Aware
Auto-detects GraphQL operations in HTTP traffic. No manual filtering through request noise.
No Schema Needed
Works even when introspection is disabled. Capture real traffic, not theoretical schemas.
Direct Export
Straight to Postman, Insomnia, cURL, or HAR. No conversion scripts or tool chains.
HAR Import
Already have DevTools network logs? Import HAR files directly. No proxy needed.
Developer Stack
npm install, Node.js runtime. Uses the tools you already have. No new languages.
Three commands. Done.
From zero to Postman collection in under a minute
Install the CLI
One command. Works on Mac, Linux, and Windows.
npm install -g graphql-grabCapture traffic
Start the proxy. Point your app at it. Use your app normally.
gqlgrab capture --port 8080Export anywhere
Generate collections for Postman, Insomnia, or plain cURL.
gqlgrab export session.json --format postmanPerfect for
Mobile App Development
Capture GraphQL calls from your iOS or Android app during development. Debug what's actually being sent.
API Documentation
Reverse-engineer undocumented GraphQL APIs. Generate Postman collections from real traffic.
Debugging Production Issues
Capture and replay GraphQL operations to reproduce bugs. See exactly what the client sent.
Test Suite Generation
Record a user session, export to Postman, generate automated API tests from real usage.
