Cline
Cline is an open-source coding agent available as an IDE extension, command-line tool, and SDK. It can read and write files, run terminal commands, and use browser and external tools.
Overview
Cline uses a human-in-the-loop workflow for interactive use. The open-source client is free for individual developers, while model inference is billed separately or supplied through the user's own provider keys.
