FAQ
A complete prompt that tells an AI coding agent exactly how to build one specific website — stack, layout, colors, fonts, copy and motion — plus a live demo built from that same prompt, so you see the result before you start.
Open a template, copy its prompt, replace [BRAND] and the other variables with your own, and paste it into your AI coding tool. Or run npx vibefather add <slug> to drop prompt.md and DESIGN.md into your project.
Any tool you can paste a prompt into: Claude Code, Codex, Cursor, GitHub Copilot, Windsurf and Gemini CLI, and app builders like Lovable, Bolt, v0 and Replit. Agents that support MCP can also search the library themselves.

For personal and non-commercial projects, yes: live demos, DESIGN.md files and most prompts are free under CC BY-NC 4.0. Using a template for a commercial site, plus Pro-only prompts, source code and high-resolution assets, comes with Pro.
Yes. Every site is written and generated by us with AI coding agents. We may take inspiration from a style and credit it on the template page, but we never copy another site's code, copy, images or logos.
