Zalcro

Zalcro is a pre-build planning tool that generates architectures, system diagrams, and build plans for AI app builders.

Zalcro is a pre-build planning tool designed for AI app builders and vibe coders. You describe your app in plain language and answer guided questions to map out your project. The platform generates an Architecture Design Document, system diagrams, step-by-step Prompt Packs for tools like Lovable, Bolt, and Replit, and sequenced ticket backlogs for Claude Code, Cursor, and Codex. It helps prevent agents from going off-rails by establishing connections and structure before you write code. Zalcro offers a free Starter plan and a paid Builder tier with exports like Markdown, PDF, DOCX, and Mermaid.
