Gio Cross Platform GUI Programming for Mobile, Desktop, WebAssembly
summary
Gio is an immediate mode GUI library that claims to let you write pure Go apps that run on Android, iOS/tvOS, macOS, Linux, Windows and runs on WebAssembly from one codebase. Demo app "scatter" is an end‑to‑end encrypted chat that uses SMTP/IMAP for transport, compiles to APK/IPA/WebAssembly, and lands in TestFlight — the UI draws via an operations buffer with low‑garbage rendering and virtualized lists so tens of thousands of rows stay fast.
