Overview
Cline (formerly known as Devins) is a massive win for the open-source community, bringing autonomous agent capabilities directly to VS Code. What sets Cline apart is its BYOK (Bring Your Own Key) model. Instead of paying a flat, high monthly fee, you plug in your choice of LLM provider — whether that is Claude 3.5 Sonnet, a cheap DeepSeek model, or a local llama model running on Ollama. In daily use, it feels extremely powerful. You give it a goal, and you can watch it open a terminal, execute npm commands, examine file diffs, and even launch a headless browser to test if the front-end elements look right. The permission prompt system is well-designed, ensuring the agent doesn't execute harmful terminal commands without your explicit approval.
