Many here probably want to know if the language actually works as intended and solves problems mentioned in it's README. I can absolutely say yes, it works!
Since November 2025 I develop a project written (almost) fully in Ü. It's a video game. It's not finished yet, but I plan to release a mostly-working version in several months, including making its source code open. So, stay tuned.
I already have ~45000 lines of code in this project. All this is manually-written (no LLMs involved). Writing Ü is nice, and code mostly works if it compiles. No single time I needed finding/fixing memory-related issues (typical for languages like C++). No single time I faced a crash in random place, if something crashed, it was a safety check. The standard library covers basic needs. unsafe code is used only to interact with SDL2 and OpenGL functions.
I spend my time mostly developing this game project. But occasionally I fix bugs and make small improvements in the language itself. This explains why there are so little commits in last months compared to time before November 2025.
