How it works for you

CP Editor eliminates all the repetitive and boring tasks during algorithmic contests. It automates all that's reasonably possible and allows you to purely focus on your code.

Fetch test cases

CP Editor can fetch testcases automatically from almost all competitive programming sites. Say bye to error-prone copy-pasting.

Code faster

Code faster with its amazing customizable code snippets. In just two seconds you can insert a whole DFS code into your editor.

Get verdicts

You can get verdicts for your sample testcases in one click by built-in checkers or checkers from testlib. You can also add your own checkers.

Run any code
At any time

We know that you want to test something without a temp file

You can run your code in one click without saving and the hot exit feature makes it easy to restore your code from the last session.

Errors and Warnings?
We lint them while you are coding

Save your precious contest time with code linting

Using Language Servers, we provide real-time linting for errors and warnings in your code, just like Intellisense in VSCode and Atom. You can see squiggles under the warnings and hover over them to get tooltips.
