Community Voice & Feedback
Looks convenient! Congratulations on the launch)
Anything that carries the Arc legacy gets an upvote!
This is clever, but how does this adapt to using a browser in full screen mode?
Local-first is a strong stance. What tradeoffs did you consciously accept by avoiding accounts/sync (multi-device, sharing, collaboration), and what’s your philosophy on where Arcmark should stop versus what integrations/export formats you’ll prioritize to keep users from feeling locked in?
The sidebar-attached approach is genuinely clever. The problem with most bookmark managers is the friction of opening a separate app or tab to access them, which kills the workflow. Having it follow the browser window natively removes that friction completely. Open source and free is the right call for a utility like this too. Congrats on the launch!
The idea is just SUPERB. I've had this in mind for along time and I've tried out supasidebar, which is also good, but too buggy at the moment. I hope this project will develop into something GREAT! Thank you for the initiative, all my support to the dev!
Visually, it looks cool. But what if I have too many bookmarks? Willit not be so much cluttered?
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 🙏
