Proxync

About

Proxync is a local-first API development environment built with Rust and Tauri. It features Smart Tunnels, enabling single-click sharing via Cloudflare, LAN, or custom domains with DNS validation. The Traffic Interceptor allows you to capture, examine headers, and replay HTTP and WebSocket requests. Auto OpenAPI automatically detects server routes in Node, Python, Go, and Java to generate immediate Swagger documentation. Its API Playground lets you test endpoints offline without any configuration. The tool is entirely private, requiring no accounts and implementing no tracking.
