Fine Structure

Fine Structure turns Claude into a full-stack app team. Describe what you need and Claude builds a complete web application on your Fine Structure account: pages, a managed database, auth and hosting, live at its own URL in minutes. The destination includes the backend, not just static files. Claude can define data schemas and query records, gate pages behind login, manage app members and access policies, store API keys as secrets, configure integrations, connect custom domains with automatic TLS, create A/B tests, and roll an app back to any saved version. Typical requests: "Create a CRM for my landscaping business with customers, jobs and invoices, publish it and give me the live link." "Add a login-protected admin page to my app and connect the domain app.mybusiness.com." "Show me the runtime errors in my published app, fix them and republish." Connecting takes one click: sign in to your Fine Structure account (free tier available) and approve access. Everything Claude does is revocable from your account's MCP tokens panel, and every change can be rolled back to a saved version.
