pen.dev is a design canvas that lets users build websites, mobile apps, and marketing assets with the help of AI agents. It supports importing existing websites or apps as editable layers, drawing and editing with a pen tool, and exporting designs as HTML, CSS/Tailwind, or images. It connects to multiple AI models and can be used via a ChatGPT or Claude subscription, API keys, or through MCP, WebMCP, or CLI.

Every crawl is diffed. Material changes are listed.
