# CanvasLink

> Instant hosting for AI-generated HTML pages. Paste code from ChatGPT, Claude, Gemini, v0, or any AI tool and get a permanent, shareable URL on your own branded subdomain in seconds.

## What is CanvasLink?

CanvasLink is a web platform that lets anyone host and share self-contained HTML pages without any technical setup. The core workflow is: paste HTML → click Publish → share a URL. No Git repository, no CLI, no build pipeline, no server configuration required.

Pages are served from Cloudflare's global network and hosted under the user's personal subdomain (username.canvaslink.app/page-name).

## Key facts

## MCP tools (for AI agents)

The CanvasLink MCP server exposes five tools:

| get_page | Read the HTML of a specific page | No |
| publish_page | Publish a new HTML page | No |
