A tailored code editor for competitive programmers


Build Test PR's Welcome MIT License

Why should you use it?

  • Provides single click compilation and execution.
  • Simple yet feature-rich design. No need to leave your editor for any task.
  • Lots of editing tools inherited from the Monaco Editor.
  • A new way of navigating between files. It's called the SELECTOR.
  • Automatically detects languages from the file name and adjusts the environment accordingly.
  • Optional RERUN button to execute code without comiling again and again.
  • Inbuilt terminal support
  • Format and Lint code on demand.
  • Custom IO mode for experimenting with your code and running single tasks.
  • Testcase mode for adding, comparing and running multiple testcases with one click. Options to save and load testcases.
  • Colored chips that show your execution result in a single glance.
  • Improved notification system to keep track of events and tasks.
  • Awesome UI customisations to fit your taste.
  • Parse testcases from contest pages with just one click. [Thanks Competitive Companion]

And lots more...


You can find the respective executables/binaries in the release page. Check the Assets for the required files. Installation guidelines for different operating systems is described below.


If you are using some variant of Linux you have two options:

  • Install using snap, if it supports. First download the .snap package from the above mentioned link. Run the command below with package-name as the name of downloaded file. You should then have the editor in your applications.
$ sudo snap install 'package-name' --dangerous
  • Use an AppImage. Download the .AppImage package and make it executable by right-clicking > properties > permissions > check the Allow executing file as program and then you can run by DBLCLICK it. You can do the same using command line as follows:
$ chmod +x 'appimage-path'
$ ./appimage-path


If you are on windows you can download the .exe setup from the link above and just run it. You may be prompted by Windows Smart Screen saying that its harmful. If so, click on More info and a button Run Anyway will appear and just proceed.


If you are on MAC then download the .dmg or the .app package from the link above. Extract the dmg package to /Applications or run the .app bundle.

Building from source

If you wish to build the project from source then check the contributing guide for initial setup and just run the electron:build npm script. You may need windows-build-tools if you are on windows.

Intended Workflow

The editor was designed with competitive programmers in mind. It introduces some tools and UI changes to usual editor so that it makes the whole experience simple and less annoying. Most of the annoying tasks are handled for you. The editor was created with the following workflow in mind.

Make sure you have the required language compiler/interpreter in your PATH variable.

Make sure the file you open or create has proper extension of supported language.

  1. Create NEW or OPEN file with the proper file extensions. Currently supports cpp, c, python, java.
  2. A code editor will open up. Write the code and now you have two options to run it.
  3. Either use Custom IO mode(when you intend to run single task) or switch to Testcase mode (if you have multiple testcases to run).
  4. After deciding the mode you can just click on the RUN button, which compiles and runs your code against all the testcases if you are in testcase mode and the chips will turn to some color depending on the execution status. You can click on the chips to view the diff or error (if any). Alternatively, the Custom IO area will get focused and you can type in the inputs and get the output stream.
  5. Optionally you have a RERUN button that runs the last compiled code.
  6. The testcases can be saved to the same directory as the Code file or in a separate directory. Also you can load them from previously saved location. The testcase reader will parse all the .in and corresponding .out files from the selected directory.
  7. So a problem in a contest can be saved as a directory with the corresponding code file and the respective testcases.
  8. When you parse a contest or a problem using competitve companion a dialog will appear in the editor asking for a directory to save the file/s.

Any suggestion to above workflow are encouraged.


If you wish to contribute to this repository then follow the steps below to build the project.

Make sure you have nodejs and npm installed. If you don't, follow the link. Also if you are on windows install some linux terminal client like git-bash. The below snippets should work fine on linux and macOS.

  • Step 1: Clone the github repository.
$ git clone
  • Step 2: Install project dependencies.
$ cd sprint
$ npm install
  • Step 3: Re-build electron to build native node packages.
$ npm install electron-rebuild
$ $(npm bin)/electron-rebuild
  • Step 4: Run the project.
$ npm run electron:serve

Every time you work on the project make sure to pull the updates from master.

Known issues

  • If electron fails to install then follow the steps below.
$ cd sprint
$ ELECTRON_MIRROR="" npm install [email protected] --verbose

pull-requests are welcomed. If you find any bugs or glitches then please take some time to file an issue. Hope you enjoy the editor:)
