I'm working on a personal AI assistant for desktop — local-first and privacy-focused (no cloud dependency), starting with a desktop app and eventually

Runtime Of Backend (Bun)

Fast startup and low idle overhead — important for an app that runs continuously in the background, not just on-demand. Native TypeScript support and a built-in bundler simplify shipping without extra tooling.

Framework of Backend (Hono)

Lightweight and built with Bun in mind, so it doesn't add framework overhead on top of the runtime's own performance. Clean routing/middleware model keeps things simple for handling auth, commands, and local model inference.

Desktop Application (Tauri + Next.js)

Tauri has a much smaller footprint than Electron since it uses the OS's native WebView instead of bundling Chromium, which makes it great for lightweight apps that stay running. It also produces smaller binaries. Next.js provides a structured, file-based routing system and a strong component ecosystem for the UI.

Would love to hear reviews and suggestions on this stack — anything you'd change, any pitfalls you've run into with a similar setup, or better alternatives worth considering?
