Cline

Cline is an open-source VS Code extension that acts as an autonomous coding agent with human-in-the-loop approval for every file edit and terminal command. It supports bring-your-own-model, so you can run it entirely against local models through Ollama or LM Studio instead of a cloud API — a private alternative to Claude Code and GitHub Copilot.

Best for: VS Code users who want an agentic assistant running on local models
