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.
