Profile

I built ApiArk because I got tired of Postman eating 800 MB of RAM, requiring a login, and storing my API keys on someone else's cloud.ApiArk is a desktop API client built with Tauri v2 (Rust + React). Everything is stored locally as plain YAML files - no account, no cloud, no lock-in. Your collections are just files in a folder, so they work naturally with Git.Key differences from Postman:- No login required - just download and start working - Git-friendly - plain YAML files, not proprietary JSON blobs - Broadest protocol support I know of - REST, GraphQL, gRPC (all 4 streaming types), WebSocket, SSE, MQTT, and Socket.IO in one tool - Local mock servers with Faker.js data and latency simula
