TRANSIT

Layer-7 Diagrams
& Live Dashboards
Overview

A Layer-7 architecture diagram builder with a built-in LLM assistant, shipped as both a browser app and a native desktop client. One codebase — a Vite + React 19 + TypeScript SPA.

Web

Served by a small Node proxy that authenticates /api/* calls to a hosted LiteLLM endpoint server-side, packaged as a hardened container.

Native

A Tauri desktop app for Windows, macOS, and Ubuntu/Linux, where a Rust proxy replaces the Node one and the LLM key lives in the OS keychain (or 1Password).

It goes further than any diagram builder: it can serve as a live dashboard hooked into your monitoring system, showing where apps will fail and what the possible impact is downstream.
