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.

AI-generated from listing dataKong is the safer default for enterprises needing a scalable, self‑hosted API gateway with AI support, while Postman excels for collaborative API design and testing.
Key differences
- •Kong is a self‑hosted, open‑source gateway focused on routing, security, and AI model traffic; Postman is a cloud‑enabled desktop app for API design, testing, and documentation.
- •Kong supports multiple protocols (HTTP, gRPC, WebSockets) and deep security controls; Postman primarily targets HTTP/REST, GraphQL, and gRPC request building.
- •Kong offers extensive plugin ecosystem and real‑time analytics; Postman provides built‑in collaboration, mock servers, and automated test scripting.
- •Kong requires more infrastructure and has a steep learning curve; Postman’s UI is ready‑out‑of‑the‑box with a gentle learning curve.
- •Kong’s pricing is freemium with self‑hosted deployment; Postman’s free tier is limited to individuals/small teams, with paid plans per user.
