demo.st

Demo.st is a platform for reserving subdomains and deploying static websites. It allows users to claim a subdomain under demo.st (like my-project.demo.st) and upload static site content as a zip file.

Core Capabilities

Subdomain Management: Check availability of subdomain names, reserve a subdomain for your account (one per account), and release reservations when no longer needed.

Site Deployment: Upload static site content as a zip file to your reserved subdomain. Content is deployed immediately and accessible via your subdomain URL.

Site Management: Remove deployed content while keeping your subdomain reservation, or fully release the subdomain to make it available for others.

Domain Model

Each account can reserve exactly one subdomain. The subdomain acts as both an identifier and the URL endpoint for your deployed site. Site content must be packaged as a zip file containing your static assets (HTML, CSS, JS, images, etc.).

Key Considerations

• One subdomain limit: Each account is restricted to a single subdomain reservation
• Zip deployment: Site content must be uploaded as a zip file, with base64 encoding being the most agent-friendly format
• Static sites only: The platform appears designed for static content deployment, not dynamic applications
• Immediate deployment: Uploaded content becomes live immediately on your subdomain

Perfect for prototyping, demos, or simple static site hosting needs.
