SnIPPETsX › Code output. Streamed live
Code output. Streamed live.
Run code and see the output instantly in your browser. Streamed stdout and stderr, exit codes and error traces for 40+ languages, with no local setup.
Including the errors — which is usually the part you actually needed.
The short answer
SnIPPETsX shows program output directly in the browser. Running a snippet streams stdout and stderr into a terminal pane alongside the editor, together with the exit code, so failures and stack traces are as visible as successful results. It works across 40+ languages.
Key features
- Errors Included — stderr and stack traces are shown, not swallowed.
- Exit Codes — Know whether it actually succeeded, not just that it printed something.
- Shareable — Send the session so someone else sees the same failure you did.
Frequently asked questions
Why is my code producing no output?
Most often the program never printed anything, or it exited early with an error. Check the stderr pane and the exit code — a non-zero code means it failed before reaching your print statement.
Can I share the output with someone?
Yes. Share the session URL and they can run the same code and see the same result.
