Cloudmark

Cloudmark keeps a bookmark collection in the cloud without an account. You pick a collection identifier called a mark, generate a secret write token, drag the bookmarklet onto your browser bar and start saving pages. Anyone holding the mark can read the collection, while adding, editing and deleting need the token, which removes the sign-up most bookmark services insist on.

The app is a React and Vite single page frontend talking to a Hono API on Cloudflare Workers, with Cloudflare D1 as the store and Tailwind CSS plus shadcn/ui for the interface. Write tokens are hashed with SHA-256 inside D1, so plaintext lives only in browser storage and the bookmarklet, and rate limits plus field length caps guard writes.

Saving and browsing are built out of a few small pieces.

• One-click save: the bookmarklet carries the mark and write token as query parameters.
• Chrome extension: a Manifest V3 build stores the active tab under an existing or new category and adds actions to the context menu.
• Keyboard-first list: slash searches, j and k move, n, e and d create, edit and delete, and the question mark opens help.
• Custom icons: a bookmark can carry an emoji, a letter mark or an uploaded SVG, ICO or PNG file.
• Two languages: the interface ships in English and Chinese.

Deployment is a button that creates a Cloudflare Worker from the repository, or wrangler from your machine after you create a D1 database and apply the migrations. Local development needs Node.js 20 and pnpm, under an AGPL-3.0 license.
