All The Best Computers Boot To… Python?

Developer jordanhubbard has released PythonOS, an operating system that boots directly to a Python interpreter and runs everything on top of it, including an optional GUI mode, according to a GitHub repository linked by Hackaday. The OS boots on x86-64 hardware or in QEMU, offers two build options for the GUI or interpreter version, and provides UNIX-like commands for interacting with the OS and disk; Hackaday reports it appears to have been created using an LLM. Hackaday notes that in 2026 the project is "more a bit of fun than a serious OS contender," and that it competes with a similar OS that boots to a BASIC interpreter featured by Hackaday on 2026-08-27.

Among all the machines of the 8-bit home computer era which booted straight to a BASIC prompt, there were a very few that went their own way with another language. The Jupiter Ace springs immediately to mind, a diminutive Z80-based machine similar to Sinclair’s ZX81, which booted to FORTH. The Ace wasn’t a commercial success, but what would have happened had it booted to a more accessible language? It’s a question jordanhubbard appears to be trying to answer, with an OS that boots to a Python interpreter https://github.com/jordanhubbard/pythonos .. The OS is Python, and everything on top of it uses the interpreter. Better still, it has a GUI mode. The OS boots on an x86-64 platform or in QEMU, and appears to have been created using an LLM. There are two build options for the GUI version or the interpreter version. It provides a set of UNIX-like commands for interacting with the OS and disk, something which brings back memories of disk-based systems back in the BASIC days. We’re surprised to see no screenshots of the GUI in action though, an omission he’d do well to correct, we think. It’s fair to say that in 2026 this is more a bit of fun than a serious OS contender, but maybe someone will run with it. It has competition too, not so long ago we featured a similar OS that runs a BASIC interpreter https://hackaday.com/2026/08/27/all-the-best-computers-boot-to-basic/ .
