4 ways to reduce Postman RAM usage
1 Use lightweight alternatives
For simple requests, curl, HTTPie, or VS Code's REST Client extension are dramatically lighter. Save Postman for complex workflows.
2 Clear request history
Postman stores response bodies in history. Periodically clear history for collections you're done testing against.
3 Close collection tabs
Each open tab holds request/response data in memory. Close tabs you're not actively iterating on.
4 Use the web version
Postman's web app works for most use cases and shares your browser's process model.
How DevPulse helps with Postman
DevPulse groups Postman's Electron processes and shows total memory at a glance.
Instead of guessing how much RAM Postman consumes or manually checking Activity Monitor, DevPulse gives you a clear, always-visible answer in your menu bar.
