Everyone uses AI now.
Nobody can share the result.

Marketing uses ChatGPT. Engineering uses Cursor. Product uses Claude. They all build amazing things — then struggle to get them online.
Sandcastle ships anything, from any AI, to a live URL in seconds.

Works with ChatGPT, Claude, Gemini, Copilot, Cursor, Lovable, Bolt — anything that writes code

Sandcastle doesn’t replace your AI tools. It gives all of them a place to deploy.

Sound familiar?

AI can build anything now.
Getting it online is still painful.

💻

“AI told me to set up a server.”

EC2, Node, nginx… I just wanted to share a prototype, not become a DevOps engineer.

🌐

“It’s live — on an IP address.”

Sharing 143.198.47.102:3000 with my boss isn’t professional. Tried CNAME, gave up.

🔓

“Anyone with the link can see it.”

It’s internal with real data. I need 5 people to see it, not the internet.

🔄

“Every change means re-deploying.”

Changed a button color. Re-upload, restart, clear cache… for a CSS tweak.

Sandcastle makes this disappear.

No servers. No IP addresses. No config files. Your AI builds something, Sandcastle gives it a real URL, instantly.

Team prototyping

Every department uses AI now.
Give them all a place to ship.

Your PM, your designer, your sales team — they’re all building with AI. They just can’t get those things in front of people. Until now.

Prototype feature ideas and share before sprint planning — no developer ticket needed.
“Build a dashboard showing our activation funnel by channel”
🎨
Design
Ship interactive mockups clients can tap through on their phones, not static screenshots.
“Mock up the new onboarding flow with working transitions”
💰
Sales
Build custom calculators and demo tools for live prospect meetings.
“Make an ROI calculator for the enterprise pitch on Thursday”
📣
Marketing
Launch landing pages, collect signups, and test messaging before a full campaign.

🔬
Research
Build surveys, data visualizations, and interactive reports for stakeholders.

Your team’s ideas, all in one place.
