--- title: Yaak canonical: https://saasranked.com/software/yaak/ category: API Clients points: 64 rank: 10 of 11 facts_checked: 2026-10-08 --- # Yaak Local-first desktop API client for REST, GraphQL, gRPC, WebSocket and SSE that stores requests as YAML files for Git. 64 points out of 100. #10 of 11 API clients. Vendor: Yaak. Website: https://yaak.app/ - Free for personal use; a license is required only when using Yaak at work [1]. - Individual costs $79 a year ($6.58 a month); Business costs $149 per user a year [1]. - Supports REST, GraphQL, gRPC, WebSocket and Server-Sent Events, each with its own docs page [2][3]. - Directory sync writes one YAML file per resource for Git, and no account is needed [2][8][9]. - Yaak says it does not support pre-request or post-response scripts [6]. Verdict: Yaak suits developers who want their collections as plain files in Git, with no account and no cloud. It covers five request types and imports OpenAPI [2][3][11]. The catch: its docs describe no scripting, tests, mock servers or published API docs, there are no cloud team workspaces, and work use needs a paid license [1][3][6][9]. Best for: Developers who want local files, Git and no account, and are happy to pay for work use. ## Points | Criterion | Line | Value | Points | Note | |---|---|---|---|---| | Systems | Other systems | macOS, Linux | 4/6 | Installers for macOS and Linux [12].
