You asked Claude, ChatGPT, or Cursor to build something. Sandcastle puts it online on your own server — no tech skills needed.
Tell your favorite AI tool what you want. It writes the code. Then one command puts it online — or the AI does it for you automatically.
Type sandcastle deploy and it figures out the rest — what language it's in, how to build it, and how to make it accessible. You get a link you can share.
With MCP, Claude and Cursor can deploy for you automatically — just ask. With the CLI, you run one command yourself. Either way, it takes seconds.
People use Sandcastle to run all kinds of things — family tools, school projects, small business apps, weekend experiments. All private, all on their own server.
Tell an AI what you need, it writes the code, and Sandcastle makes it a real website you can open on your phone, share with family, or use at work.
Each app runs in its own sealed space so it can't touch anything else. Your data stays on your own machine, the link is secure, and you decide when it goes away.
Sandcastle figures out what the AI made and how to run it. You don't need to know what "Next.js" or "Python" means.
Your own server or home device. No cloud accounts, no monthly fees, no one else sees your data.
AI-generated code runs in a sealed space that can't access your files or anything else. If something's wrong with the code, it can't cause harm.
