The best open source command-line AI coding agents and harnesses in 2026, ranked by GitHub stars: OpenCode at 165k, the new Pi harness, OpenHands, Cline, Goose, Aider, Crush, Qwen Code and more - with honest notes on licenses, local models, and which projects are dying.

The CLI coding agents worth using in 2026: Claude Code on Opus 4.8, OpenAI Codex on GPT-5.5, OpenCode's growth to 165k+ stars after its Anthropic login dispute, Cursor CLI's pending $60B SpaceX acquisition, Antigravity CLI after the Gemini CLI shutdown, and where Aider and the open-source Pi harness still fit.
