Cline

Cline is an open-source autonomous coding agent that works across development environments rather than only providing code suggestions. It is available through IDE integrations, a terminal-based CLI, and an SDK for building custom agent workflows. In its editor experience, Cline can create and modify files, execute commands, browse the web, and use external tools, while keeping humans involved for important approvals. The CLI can also run headlessly for scripting, CI/CD pipelines, and automated code review tasks. Developers can connect Cline to services such as Slack and Telegram, while the SDK supports custom tools, connectors, multi-agent teams, and scheduled automations. Its open-source approach makes it particularly relevant for developers who want more control over their coding-agent setup.
