CP Editor is a Qt-based, cross-platform IDE designed specifically for competitive programming. It automates compiling, running, and testing code against fetched sample test cases, and can submit solutions directly to Codeforces.
Use cases
- automatically fetch sample test cases from Codeforces or AtCoder
- compile and run C++ solutions against multiple test cases instantly
- submit solutions to Codeforces from the editor
- get real-time linting and error highlighting while coding
- quickly test code snippets without saving files
When to choose
- you compete in Codeforces, AtCoder, ICPC, or OI contests and want an integrated edit-compile-test loop
- you want a lightweight editor tailored to competitive programming instead of a full IDE
- you want one-click test case fetching and verdict checking
When to avoid
- you need a general-purpose IDE for large software projects with debugging and refactoring
- you work primarily in languages other than C++, Java, or Python
- you need built-in version control or team collaboration features
