Transcript
Qt commercial costs $5,500/year per developer. Slint does it free. This Rust toolkit builds smooth native interfaces for embedded devices and desktops across C++, Rust, and JavaScript. A live visual designer previews your UI the instant you type. At under 300KB binary footprint, it runs on tiny microcontrollers where Qt can't even load. The royalty-free license means no per-device fees. Over 17,000 GitHub stars prove the momentum. Would you switch from Qt to this? Comment below.
