What makes it different
Four frontier models debate instead of single-model review avoiding blind spots
All gate code and tools are open source and MIT-licensed
Never trains on user code or content
Pay-per-call pricing with no token markup or per-seat fees
Every status check is signed and publicly logged so verification is cryptographic, not based on trust in the company
Catches silent payment address or network changes that would otherwise go unnoticed
Free connection with no sign-up, plus pay-per-call options for flexible scaling
Works across multiple AI agent frameworks (Claude, Cursor, VS Code, Gemini, ChatGPT) via standardized MCP protocol
Local agent signing tool keeps private keys on the user's machine, never uploaded to servers
