Your bookmarks, attached to any browser as a sidebar
A native macOS bookmark manager that attaches to any browser window as a sidebar. Open source, free, and local-first. Heavily inspired by Arc Browser's sidebar.
Hey everyone! 👋
Really excited to launch Arcmark on Product Hunt today. As always, huge thanks to @fmerian for hunting!
I've been using Arc as my primary browser for a while now. When I tried switching to other browsers, the lack of quality sidebar and link organization was one of the few things I couldn’t replace anywhere else.
So I built Arcmark, it's a native macOS bookmark manager that attaches to any browser window as a sidebar.
What Arcmark does:
✻ Attaches as a sidebar to your browser window and follows it around (uses macOS Accessibility APIs). Works with Safari, Chrome, Brave, and others.
✻ Workspaces + nested folders, drag-and-drop reordering, and custom workspace colors. Heavily inspired by Arc's sidebar UX.
✻ Local-first. No accounts, no cloud sync. Everything lives in a single JSON file: ~/Library/Application Support/Arcmark/data.json
✻ Import from Arc. You can bring all your pinned tabs and Spaces from Arc with exactly the same folder structure. Probably the easiest way to get started for Arc users. There is also an option to bring Bookmarks from Chrome.
✻ Works standalone too (even if you don’t want the “attached sidebar” mode).
Arcmark is also fully open source and free. Would really love to hear your thoughts 🙏
