Postman vs. Insomnia
Learn why Postman is the go-to solution for collaborative API development, testing, and more.
Why Postman?
Postman is the leading API platform for organizations, streamlining API development and driving innovation. Unlike traditional, single-player API management tools, Postman fosters team collaboration across the entire API development lifecycle, from creation to deployment.

What about Postman vs. Kong?
Insomnia is a subsidiary of Kong, which offers a range of point solutions for managing APIs and microservices. Kong's products were not developed as part of a single, cohesive strategy; many, like Insomnia, were acquired and later integrated into the ecosystem, resulting in a fragmented user experience. In contrast, Postman was built with a unified vision to serve every stage of the API lifecycle within a single platform.
Industry recognition
Don't just take our word for it—learn why G2 recognized Postman as the #1 API platform in 2024.
