Using Tauri makes a lot of sense here keeping the binary size small while having Rust's safety for the backend is a huge win over Electron. The proxy tauri backend for live previews sounds like a clever way to handle the dev-to-prod feedback loop. Curious if you have hit any specific hurdles with AppleScript for the system level automation yet?

This looks like a massive level-up for the "AI-to-Software" pipeline. Moving from simple web-app generation to actual native desktop apps is a huge step for utility—especially if it handles the boilerplate for system-level APIs.

The fact that it's open-source is a great move for the HN crowd. I’m curious, what are you using under the hood for the desktop shell? Is it wrapping an Electron/Tauri instance, or is it generating something like Rust/Python natively?

Clean UI on the site, too. Excited to see where this goes!

This is a killer niche. Integrated Postgres solves the biggest headache with ephemeral sandboxes—actually keeping the agent's memory. 300ms is already solid, but getting under 100ms usually means moving from "booting" to Firecracker Snapshots.

If you haven't yet, look into pre-warming TAP devices and bypassing the HTTP API for direct process management. Exciting stuff!
