Artifact viewer

Zero-retention artifact viewer for AI outputs.

Artifact content lives in the URL fragment, so in static mode the static host does not receive artifact content on the page request.

Fragment links can still appear in browser history, screenshots, copied messages, extensions, and other places you share or run your browser.

Why does this URL look weird?

Static boundary

The browser decodes markdown, code, diffs, CSV, and JSON locally from the fragment after the shell loads.

Source code, issues, releases, and self-hosting notes.

ProtocolPayload format docs

Fragment key, codecs, envelope fields, and size limits.
