Good to know
Static files only
Upfling hosts static files. Claude Artifacts typically produce self-contained HTML that works as-is. For most pages, ask Claude for a single HTML file with inline CSS and the download will be ready to upload directly. If Claude generates a React component (.jsx), use the Artifact Converter to turn it into a hostable HTML page. ChatGPT follows a similar flow. See Websites for the general approach.
