Cline is the open-source coding agent that defined the in-editor agent category, with 5M+ installs across VS Code, JetBrains, and Cursor itself. Its Plan/Act modes separate thinking from doing — the agent proposes a plan you approve before it touches files or runs commands. Apache-2.0 licensed with full bring-your-own-key model freedom, MCP integration, and deployment options up to on-prem and air-gapped for enterprises.
Windsurf (formerly Codeium) is an AI-first code editor featuring Cascade — an agentic flow that can handle multi-file, multi-step coding tasks. It combines the familiarity of VS Code with powerful AI capabilities including code generation, refactoring, and terminal integration.
