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.
Roo Code began as a fork of Cline and grew into its own power-user favourite. Its signature feature is modes: switchable personas like Architect (plan), Code (build), and Debug (fix), plus fully custom modes with their own prompts and tool permissions. It supports auto-approval settings for hands-off runs, MCP servers, and any OpenAI-compatible provider. The trade-off for all that configurability is a steeper setup than Cline — and, like every BYO-key agent, your API bill scales with how hard you run it.
