What is egui_tracing and how do I add it to my egui app?

It's a widget for live log viewing in egui/eframe, especially WASM. Crate add, init subscriber, plop widget in UI. Docs walk you through.

Does egui_tracing work on desktop or only WASM?

Works everywhere egui does, but shines in WASM sans terminal. Desktop? Fine fallback.

Risk of bloat if untuned, but caching evicts smartly. Monitor heap, set limits.

No terminal in WASM? Brutal. egui_tracing crams a live log viewer into your egui app, but is it the savior or just another band-aid?
