# Insomnia

> An open-source workspace for designing and testing APIs

Insomnia is an API client for designing, testing, and debugging requests. It supports protocols including HTTP, GraphQL, gRPC, WebSockets, and server-sent events. Developers can start with an OpenAPI specification, organize request collections, create mocks, and use scripts before or after requests for repeatable tests.

Its MCP client also tests server tools, resources, and prompts. Work can stay local, use Git, or sync through the cloud, depending on the team's workflow. Kong Konnect connects an API catalog to the workspace, and command-line tools support automation. These options keep API design and investigation close to the requests and checks the team uses.
