Rust + egui, but it's a far cry from the convenience or iteration speed of the web. Wherever possible, I build webapps instead, just because it's so much faster to get results (especially with LLMs!)

With that being said, I'd like to try the modern .NET stack sometime. Shame that the UI side of things is still largely Windows-only, and even Microsoft themselves don't know which UI framework they're using this week.
