Insomnia

What is Insomnia?

Insomnia is an open source API development platform that enables developers to design, test, and debug APIs across multiple protocols and architectures. The tool supports HTTP, REST, GraphQL, gRPC, SOAP, and WebSocket APIs, making it suitable for teams working with diverse API technologies. The platform is designed for API developers, backend engineers, and QA teams who need a unified environment to build and validate APIs. Insomnia provides features for creating requests, inspecting responses, and managing API workflows without requiring payment, as the core product remains free and open source. Key capabilities include support for multiple API standards, allowing developers to work with contemporary and legacy API types within a single application. The open source nature means the codebase is publicly available on GitHub under Kong's organization, enabling community contributions and transparency. Insomnia serves as an alternative to other API development tools, positioning itself in the API testing and development category. The platform is maintained actively, as evidenced by ongoing GitHub activity, and includes community support channels for users seeking assistance. Organizations can deploy Insomnia across their teams at no licensing cost, making it accessible for startups, enterprises, and individual developers alike.
