Overview
Cline is an open-source coding agent available in several editors and IDEs. It can read and edit files, run commands, use MCP servers, and request approval before selected sensitive actions.
Users can select their own model provider or use Cline’s managed service, which provides flexibility while making costs dependent on inference usage. A paid Enterprise offering adds management, security, and collaboration features.
