The drift check — $12, one-time.

Already have a design system? Bring it. Keep your agent on-brand.

• Your own tokens, checked. Give your agent your design tokens. It checks its own code against them with swatchdog as it builds — catching and fixing spacing, color, radius, and type drift before you ever see it.
• Your own dedicated key. A personal license with a generous usage envelope — no daily request caps for active developer workflows. Runs in Claude Code, Claude Desktop, Cursor, and any client using the standard MCP config. (Note: The web-based claude.ai interface does not support custom headers yet, so this key is for your local IDE/CLI tools.)
• One-time. No subscription. Buy once, it's yours.
• Stateless & private. Your code and tokens are checked in the moment and never stored.
