ApiArk is a lightweight, privacy-focused API development platform built with Tauri v2 for Windows, macOS, and Linux. It enables developers to build, send, test, and debug API requests without requiring an account or cloud storage. The application supports REST, GraphQL, gRPC, WebSocket, SSE, MQTT, and Socket.IO protocols. Requests and collections are stored locally as YAML files, making them compatible with Git workflows. Developers can automate testing with TypeScript scripts, collection runners, and scheduled monitors. Additional tools include local mock servers, response comparisons, API documentation generation, and HTTP traffic inspection. ApiArk also supports importing collections from popular API clients and extending functionality through plugins.
