MetriX — Developer Infra Monitoring HUD

Overview

MetriX replaces eight separate daily-driver tools with a single PgUp keypress. A Rust background thread emits system metrics via Tauri events every two seconds — zero JS polling, zero UI-thread blocking. The reqwest HTTP client inside the Rust process makes API requests without any browser CORS restrictions. An embedded tiny_http server in the Rust binary provides a webhook inspector that requires no external proxy.

Tech

Tauri v2 with ActivationPolicy::Accessory keeps MetriX invisible until the global shortcut fires. Svelte 5 runes with a single AppState class drive the 33-panel UI. The Rust backend exposes 34 command handlers covering sysinfo metrics, Bollard Docker calls, reqwest HTTP requests, shell command streaming, and the tiny_http webhook listener. Shiki provides syntax highlighting across config editor, API tester, and log viewer panels.
