Carbon is an Android application developed by Lucas Aschenbach. It is a free program in the Business & Productivity category. Carbon allows users to connect to any SSH server and access a full-featured Code Editor, File Explorer, and Terminal, all from their mobile device.

The program offers a robust text editor specifically designed for coding, with a draggable cursor and auto-formatting features. Users can view their code files properly highlighted with syntax highlighting support for over 180 languages. The built-in terminal emulator allows users to control their server with xterm-256color output, although some functionality is still being implemented.

One of the key features of Carbon is the SFTP functionality, which allows users to easily manage their files by adding, removing, moving, and renaming them with just a few clicks. Additionally, the program offers local port forwarding, enabling users to view applications running on their remote server as if they were running locally.

It is important to note that while Carbon has recently reached a stable state, the app is still in preview, which means that some functionality may still be fragile. Overall, Carbon provides a convenient and comprehensive solution for developers who need to access and edit code on remote systems using their Android device.
