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

@MarcusWeinberger Any chance I could get the admin password so I can XSS this?

MarcusWeinberger (774)

@AmazingMech2418 hah nope, that admin panel is for us to moderate and kick any abusers

AmazingMech2418 (1041)

@MarcusWeinberger You have a rickroll code though. LOL! And I'm 14500 guesses in and still haven't found the password.

MarcusWeinberger (774)

@AmazingMech2418 yes we do, that's to mess with kfir. he's our friend that was abusing our previous XSS bug. And good luck cracking the password, it's very secure ;)

@AmazingMech2418 suuuuuuuuure buddy, rafi can tell me himself if he wants me to make it public

AmazingMech2418 (1041)

@MarcusWeinberger I can tell you I did not use inspect. Go on and I'll ask him to repeat it again. LOL!

MarcusWeinberger (774)

@AmazingMech2418 you can set your username to whatever. rafi can tell me himself if he wants me to release it, which I doubt he does, because it would be a major security violation

AmazingMech2418 (1041)

@MarcusWeinberger LOL! You got me... (I just want to rickroll people! LOL!)
