Yaak

Send and organize API requests in a local-first desktop client.

Yaak is a desktop API client for HTTP, GraphQL, gRPC, WebSocket, and server-sent events. It supports environments, imports from other API tools, encrypted secrets, and sharing request collections through Git.

Its Rust workspace implements request handling, storage, synchronization, and desktop integration through Tauri, alongside a React interface. The source is MIT-licensed; official prebuilt binaries have separate commercial-use licensing terms.
