Cosmopolitan: Compiling Python. Cosmopolitan is Justine Tunney’s “build-once run-anywhere C library”—part of the αcτµαlly pδrταblε εxεcµταblε effort, which produces wildly clever binary executable files that work on multiple different platforms, and is the secret sauce behind redbean. I hadn’t realized this was happening but there’s an active project to get Python to work as this format, producing a new way of running Python applications as standalone executables, only these ones have the potential to run unmodified on Windows, Linux and macOS.
