Cline is an open-source VS Code extension that turned the "bring your own API key" model into a legitimate alternative to Cursor and Copilot. It has over 5 million installs, an active community, and an agentic workflow with plan/act modes, terminal execution, browser automation, and MCP support. We tested Cline as a daily driver for 5 months and evaluated its performance.
The one-line verdict is 4.0/5, making Cline the most capable free AI coding extension for VS Code, with the Plan/Act workflow being the best process discipline among agentic coding tools. However, Cline costs $0 for the extension but incurs an average API bill of $60-90/month, which is more than a Cursor Pro or Copilot subscription.
