If you aren’t looking for languages that have more fancy memory management things (ref counting, borrowing or similar) then the active ones I know of are in alphabetical order: C3, Hare, Jai (might be slightly more of a C++ alternative), Odin and Zig. Additionally: Hare stated Win and Mac will be unsupported. Jai is still closed source.
