Cline

Open-source agent (VS Code/CLI)

FreeAI IDEs & coding agentscline.bot

What it is

An Apache-2.0 autonomous coding agent with roughly 64k GitHub stars, shipping as a VS Code and JetBrains extension, a CLI, an SDK and a web kanban board. Its Plan/Act split makes the agent draft an approach before touching files, and every diff and terminal command needs approval by default.

Why it earns a slot

The transparency pick: you see every diff and every command before it runs, and you pay providers directly with no markup. Works with Claude, GPT, Gemini, Ollama and 200+ models via OpenRouter, so nothing is locked in.

Know before you commit

BYO-key means costs are unbounded and easy to underestimate — one long agent session on a frontier model can run to several dollars.
