What is it?

Cloudmark is a cloud bookmark manager with no login or registration. You create a collection identifier (a "mark") and a secret write token, then install a bookmarklet on your browser bookmarks bar to save the current page. Anyone who knows the mark can view the collection, while adding, editing, or deleting entries requires the write token.

The project runs as a single-page React app served by a Cloudflare Worker with a Hono API, storing data in Cloudflare D1. Write tokens are hashed with SHA-256 before storage, and rate limits and field length limits are applied. A Manifest V3 Chrome extension can save the active tab to an existing or new category and adds context menu actions.

The interface supports keyboard navigation, instant filtering and sorting, custom icons (emoji, letter marks, or uploaded SVG/ICO/PNG), per-bookmark notes, and English and Chinese localization. It can be deployed to Cloudflare with one click or run locally with pnpm and Wrangler.
