Show HN: Arcmark – macOS bookmark manager that attaches to browser as sidebar

https://github.com/Geek-1001/arcmark
31•ahmed_sulajman•2h ago
Hey HN! I was a long-time Arc browser user and loved how its sidebar organized tabs and bookmarks into workspaces. I wanted to switch to other browsers without losing that workflow. So I built Arcmark, it's a macOS bookmark manager (Swift/AppKit) that floats as a sidebar attached to any browser window. It uses macOS accessibility API to follow the browser window around.

You get workspace-based links/bookmarks organization with nested folders, drag-and-drop reordering, and custom workspace colors. For the most part I tried replicating Arc's sidebar UX as close as possible.

1. Local-first: all data lives in a single JSON file ( ~/Library/Application Support/Arcmark/data.json). No accounts, no cloud sync.

2. Works with any browser: Chrome, Safari, Brave, Arc, etc. Or use it standalone as a bookmark manager with a regular window.

3. Import pinned tab and spaces from Arc: it parses Arc's StorableSidebar.json to recreate the exact workspace/folder structure.

4. Built with swift-bundler rather than Xcode.

There's a demo video in the README showing the sidebar attachment in action. The DMG is available on the releases page (macOS 13+), or you can build from source.

This is v0.1.0 so it's a very early version. Would appreciate any feedback or thoughts

This looks like a nice project!

I always have a love hate relationship with bookmarks. I tend to treat bookmarks as a write once read never datastore. I have a set of 2-3 bookmarklets that I use often, but almost never use other bookmarks. I do keep an archive of pages or links I find interesting, but I store those in a separate archive (self hosted Karakeep).

So, I’m legitimately curious — for the author or others — how do you use bookmarks? What is your personal usage pattern? Do you have many pages you need to keep track of? Is there much churn or adding of new bookmarks? I’d like to make beater use of my stored links, but right now it is really a write-only archive.
