Score: 5.8/10 (Innovation: 6, Technical: 5, Documentation: 8, Utility: 4)

Hashpage is a document format and reference client that stores semantic HTML in the URL fragment, compressed and base64url-encoded, so the link itself carries the document without server storage. It emphasizes reader-controlled themes and privacy (fragment never sent to server), with sanitization and preview-link options for social sharing.

Target audience: web developers, privacy-conscious users, technical writers
