Best for
Developers who want a terminal-based AI coding agent that can switch between multiple LLM providers and local models while maintaining strict control over costs and privacy.
Not ideal for
Windows users, as the tool is primarily designed for macOS and Linux environments, and users looking for a cloud-synced or GUI-based experience.
A powerful, privacy-focused alternative to Claude Code that excels in flexibility and cost transparency, making it ideal for power users who want to manage their own AI toolchain.
The tool has moved away from specific free-model presets like stealth/ox-alpha in favor of live free-model discovery via OpenRouter, and continues to refine its session checkpointing and sandbox security features.
