Postman vs Yaak
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.
Yaak is a local-first API client built by the original creator of Insomnia, designed to work fully offline without requiring an account. It stores data locally rather than in the cloud, encrypts secrets with ChaCha20-Poly1305, and supports plain-text Git syncing so request collections can be versioned alongside code.
Free for individuals and small teams; paid plans start at $14/user/month.
- Industry-standard for API testing

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.
