dupl.kit - Collaborative Text Editor and IDE

Code and collaborate with friends, all in real time baby! Watch their cursors move around the page and talk in chat!


  • Text editor with live operational transformations: see changes made by fellow coders in real time (baby)
  • Private files: files saved in local storage
  • Live chat: same style as repl.it, protected from XSS ;)
  • Multiplayer cursors: view other coder's cursors (credit: @MarcusWeinberger)


  • Only local files will run and output code, global file running coming soon!

Supported Languages

  • PYTHON run any code with console output (input and support for external libraries coming soon)
  • HTML render your webpage in an embedded iframe
  • JS use scripts inside your HTML dupl
  • CSS style your html dupl

All in your browser!

Created by @rafrafraf with some help from @MarcusWeinberger
