Run Python online

Run Python code online in a fast, secure sandbox — no setup. Run Python 3 online instantly — no setup, popular libraries preinstalled. Generate, fix and explain code with one-click AI. Write Python in the editor, press Run, and your code executes in an isolated Linux sandbox powered by CPython 3.14 (numpy, pandas & requests preinstalled) — nothing to install. Need a starting point or stuck on an error? Let the built-in AI generate, fix, comment or optimize your code, streamed straight into the editor.

Instant execution

Cached, pre-built environments start fast and run your Python in a secure sandbox with stdin support.

AI built in

Generate from a prompt, fix the exact error you hit, add comments or optimize — the result appears live in the editor.

Isolated & safe

Every run happens in a throwaway sandbox with strict time and memory limits — your machine never runs the code.

Saved history

Signed-in runs are saved so you can revisit and share what you ran.

FAQ

Is the Python Code Runner free?

Yes. Running code is free — guests get 5 runs a day, a free account gets 20, and paid plans get 500. Only the optional AI actions use credits, like the rest of CodingFleet.

Which Python version / toolchain is used?

Your code runs with CPython 3.14 (numpy, pandas & requests preinstalled) inside a sandboxed Linux environment.

Can I read input from stdin?

Yes — open the “Standard input (stdin)” panel under the editor and type the input your program should receive.

Do you save my code?

When you're signed in, each run is saved to your history so you can find it later. Your latest editor content is also kept in your browser between visits.
