Ace vs Firepad vs Tandem

Ace is a standalone code editor written in JavaScript. Our goal is to create a browser based editor that matches and extends the features, usability and performance of existing native editors such as TextMate, Vim or Eclipse. It can be easily embedded in any web page or JavaScript application.

An open source collaborative code and text editor. Share documents and see changes occur in real-time.

Tandem is a decentralized, collaborative text-editing solution. Tandem works with native text editors, works across different editors, and uses peer-to-peer connections to facilitate communication. Tandem exists as a set of plugins for native text editors. We currently support Sublime Text 3 and Neovim. We also unofficially support Vim.
