Flux is a high-performance, multiplayer code editor from the creators of Atom and Tree-sitter. It's also open source.
Flux is built from the ground up to be fast. It uses all your CPU cores to stay responsive, even in massive codebases.
Flux leverages your GPU to render the UI, ensuring consistently smooth 120fps scrolling and typing.
Code with your team in real-time. Share your workspace, follow each other's cursors, and communicate without leaving the editor.
Powered by Tree-sitter, Flux understands your code's structure, providing precise syntax highlighting and intelligent navigation.
