You describe what you want. Claude Code builds it inside a folder on your computer. Mosaic puts it online — with a database, file storage, sign-in, email and more, ready on day one. Nobody here needs to write code.
The big picture
Keep this picture in mind for everything else on this site.
The workspace. Where your files live and where you watch everything happen.
The builder. Reads, writes and runs things inside your folder when you ask.
The know-how. Step-by-step instructions Claude loads for specific jobs, like using Mosaic.
The home online. Where your project goes live, with everything a real app needs.
You talk to Claude. Claude uses its skills to build inside your folder, then puts the result on Mosaic. Your job is describing what you want and checking the results — the same loop whether you're building a sign-up form or something nobody's asked for yet, like the Light Lab.
Where to go next

A pure creative toy — proof that "describe it to Claude" isn't just for forms.
