Being a creator of Sciter (https://sciter.com https://sciter.com), I would insist it is good in the sense: 0. Really cross platform: Win, Mac, Linux, Mobiles, IoT. 1. Uses stable (10+ years) and compact API - 30 functions really 2. Uses well known and time proven constructs: HTML/CSS 3. Battle tested, in production since 2006, Sciter UI works on 460 mln PCs and Macs. Ah, and Sciter/Rust is already here: https://github.com/sciter-sdk/rust-sciter https://github.com/sciter-sdk/rust-sciter
