Postman vs Thunder Client
Side-by-side comparison of features, pricing, ratings, and alternatives.
Postman is an API platform for building and using APIs. Postman simplifies each step of the API lifecycle and streamlines collaboration.
Thunder Client is a REST API testing extension that runs inside VS Code and JetBrains IDEs, letting developers send requests and inspect responses without leaving their editor or switching to a separate app like Postman. Collections and environments are stored locally, and can be synced to a team's own Git repository for version-controlled collaboration. Beyond manual request testing, Thunder Client supports scripted assertions, WebSocket, SSE, and gRPC testing, and a CLI for running collections inside CI/CD pipelines. It has been downloaded more than six million times since launching in 2021, positioning itself as a lighter, IDE-native alternative to standalone API clients.
Free for individuals and small teams; paid plans start at $14/user/month.

Postman Reviews
4.5 (2)Solid choice
I switched to Postman last quarter and haven't looked back. Good team collaboration features. One minor gripe: team plans get pricey at scale, but it hasn't been a dealbreaker. Would recommend to anyone considering it.
Great tool for development
Been a daily user of Postman for a while now. Free tier covers most individual needs. No major complaints so far. Would recommend to anyone considering it.
