Cline

Cline Bot

Cline is the most-installed open-source coding agent for VS Code. Its plan-and-act loop asks for explicit human approval on each tool use by default, which makes it slower than fully autonomous harnesses but easier to trust. Bring-your-own-key means the baseline cost of running Cline is whatever your model provider charges.
