G: Short answer: I can’t run Prolog in this chat (I can run Python), but I can write, debug, and explain Prolog code for you — and I can point you to several solid websites where you can paste-and-run Prolog right away. citeturn0search2turn0search0

Where you can run Prolog online (fast picks and why)

SWISH (SWI-Prolog for SHaring) — full SWI-Prolog in the browser, notebook-like, great for sharing examples and using SWI libraries. Good first choice. citeturn0search0
OneCompiler (Prolog) — simple paste/run REPL, quick for tiny tests and learning. citeturn0search1
JDoodle (Prolog) — web IDE + share links; handy for quick prototyping. citeturn0search3
OnlineGDB (Prolog) — online editor + run/debug UI if you want step-through runs. citeturn0search5
TutorialsPoint online Prolog — quick playground with basic debugging tools (useful for teaching/examples). citeturn0search4

Minimal example you can paste into any of them

% hello.pl
:- initialization(main).
main :-
    write('Hello, world!'), nl,
    halt.

Paste that into SWISH/OneCompiler/JDoodle and press Run — you’ll see Hello, world! in the output. citeturn0search0turn0search1
