Community Feedback
Strengths
- Now auditable and self-hostable after open-sourcing
- Fast, native Rust TUI
- Native ACP and MCP support
- Backed by Grok 4.5's agentic coding stack
Weaknesses
- Open-sourced in apparent response to a data-exfiltration privacy scandal
- No external contributions accepted despite being open source
- No versioned GitHub releases; very young public repository (created July 2026)
- Grok-model-centric — limited value without xAI access or a heavy self-host setup

When to Use
Best for: Existing Grok/xAI users wanting a terminal coding agent tied to Grok 4.5, or teams wanting to audit/self-host the tool after the 2026 data-upload incident
Avoid when: You need a community-contributable open-source project or don't want a Grok-only default model
