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.

It is a high-performance, multiplayer code editor from the creators of Atom and Tree-sitter. It efficiently leverages every CPU core and your GPU to start instantly, load files in a blink, and respond to your keystrokes on the next display refresh.

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

Graphite enables convenient, secure, decentralized, and user-owned file creation, file storage, communication, and sharing.

It is an efficient and minimal open-source collaborative text editor based on the operational transformation algorithm. It lets users collaborate in real-time while writing code in their browser. It is completely self-hosted and fits in a tiny Docker image, no database required.

It tries to bridge the gap between editing explicit, unambiguous content like Markdown or XML, and classical WYSIWYG editors.

Conclave is a peer-to-peer, real-time, collaborative text editor built from scratch in JavaScript.
