Build APIs that work.
Deliver high quality APIs through standards and collaboration with the Insomnia API development platform.
Open Source API Client
There is a reason developers love Insomnia. With our streamlined API client, you can quickly and easily send HTTP, REST, gRPC, GraphQL, Websockets, SOAP, and SSE requests directly within Insomnia.
Native API design and mocking
Build consistently reliable APIs with Insomnia. Validate OpenAPI specs through real-time linting and simulate functionality using secure mock servers — locally or in the cloud.
Centralize and Automate Tests
Create comprehensive API tests for every collection with pre-request and after-response scripting. Use the Collection Runner to execute unlimited test runs and detect any breaking changes. Use the Inso CLI to unlock CI/CD automation and integrate with your CI/CD process to build out an API testing pipeline.
Accelerate development with AI
With the AI Runner, available on all Insomnia plans, developers can write code once and easily consume all of the LLMs supported by the Kong AI Gateway. Develop APIs more efficiently and securely with AI semantic caching and key security guardrails available out-of-the-box.
