HTML Preview Tool
Paste or upload standalone HTML — including Archify architecture diagrams — preview it in a sandbox, and publish a short shareable link.
Security considerations
Iframe sandbox
Preview uses srcdoc plus sandbox="allow-scripts allow-popups allow-downloads allow-modals". Scripts inside the HTML can run, but they do not get the parent origin (allow-same-origin is omitted).
Do not paste untrusted HTML that you would not open as a downloaded file.
Share links
- Public links are viewable by anyone with the URL
- Password links hide the source until the password is supplied
- Optional expiry returns HTTP 410 after the timestamp
- Only the creating session can update or delete a page
Privacy
HTML is stored on the server so the short link can be reopened. Treat diagrams that include internal hostnames or secrets as confidential and use a password or skip publishing.
