what it is
Zalcro is the pre-build planning tool for vibe coders. When you build an app with AI without a plan, every new feature risks breaking what came before. Zalcro maps out your architecture: database, system logic, and component boundaries before you start building. It gives your AI coding tool the exact architecture it needs to build in the right order. The result is a build-ready plan you can paste directly into Lovable, Replit or Bolt.new, or connect via MCP to Cursor, Claude Code or Codex. Free to start.
