What it is

Yaak is a local-first desktop API client for sending requests, debugging APIs, and collaborating through Git. It runs on Linux, macOS, and Windows, and supports HTTP/REST, GraphQL, gRPC, WebSocket, and server-sent events. Users can arrange requests in workspaces and folders, switch environments, and reuse authentication and variables. Directory sync stores requests, folders, and environments as individual YAML files for Git workflows.

Yaak imports work from Postman, Insomnia, Bruno, OpenAPI, and curl. Plugins support authentication, importers, and template functions, with a 1Password plugin for retrieving passwords. The desktop app stores data locally and sends API requests directly to chosen servers; it has no built-in analytics or tracking. Optional workspace secret encryption uses XChaCha20-Poly1305, with the master key protected by the operating system keychain. Free use is for personal purposes; commercial use requires a license. Individual Annual costs $79 a year, and a 30-day trial is available.

Strong points and limits

Strong points

  • Supports five API protocols
  • Imports Postman, Insomnia, Bruno, OpenAPI, and curl
  • Local storage with no built-in analytics or tracking
  • Free personal-use plan and 30-day trial

Limits

  • Free plan excludes commercial use
  • No scheduled runs or mock server
  • Individual license cannot be transferred

Who it suits

Yaak suits API developers and teams sharing requests through Git, especially those seeking control over local API data. Commercial users need a license, and the Individual license is assigned to one person and cannot be transferred.

Verdict

Yaak combines a broad protocol list with local storage, Git workflows, and import options. Personal use is free, while commercial licensing and the non-transferable Individual license are important constraints to check.
