CSV Align ships as two local application runtimes over the same shared Rust backend. The local web app starts an Axum server on 127.0.0.1:3001, serves the built React frontend from /Users/vriesd/projects/csv-align/frontend/dist, and lets browser mode call HTTP routes under /api/*. The desktop app uses Tauri 2 to host the same frontend in a native WebView and routes operations through registered Tauri commands.

Both runtimes create in-memory comparison sessions, load two local CSV files, suggest mappings, run comparisons, and support CSV, HTML, pair-order, and comparison snapshot flows. The frontend switch in /Users/vriesd/projects/csv-align/frontend/src/services/tauri.ts keeps browser and desktop behavior aligned by choosing either HTTP calls or invoke(...) calls at runtime.

Runtime summary

Runtime	Entry point	Transport	Primary details
Local web app	/Users/vriesd/projects/csv-align/src/main.rs	HTTP /api/*	Builds an Axum router, binds to 127.0.0.1:3001, and falls back to static frontend files.
Desktop app	/Users/vriesd/projects/csv-align/src-tauri/src/main.rs	Tauri commands	Registers command handlers, manages the shared SessionStore, and enables native file dialogs.
