Decantr

AI Frontend Governance for production codebases touched by AI agents.

Decantr is the governance layer between product intent and AI-edited frontend code. It gives coding assistants three things they don't have on their own: typed contracts, route-scoped context, and machine-actionable evidence, so UI changes stay coherent instead of drifting prompt by prompt. The model still writes the code; Decantr defines the contract, context, and verification loop around it.

AI generates the interface. Decantr proves, with local evidence, whether the outcome stayed aligned.

Greenfield Starter Kits

1. Scaffold from a blueprint

npx @decantr/cli new my-app --blueprint=esports-hq
cd my-app

A starter kit is a published app composition — theme, sections, pages, layouts, voice, and personality. It is a starting point, not the product center. The public registry now keeps blueprint discovery intentionally small: Featured and Certified are the strongest default picks, All shows supported contracts, and Labs is opt-in for promising but less-proven directions.
