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 🙏

@lisadziuba my main motivation was to find a way to finally jump off Arc. I got so used to the structure of having a dedicated workspace for each project in a sidebar as a way to organize bookmarks/links that I couldn't have done that before. With Arcmark it's much easier for me to try other browsers now

Also, building Arcmark was my excuse to test the latest Codex models more heavily 😅

minimalist phone: creating folders

Visually, it looks cool. But what if I have too many bookmarks? Willit not be so much cluttered?

@busmark_w_nika I'd usually split them into separate workspaces, so each workspace is extremely focused on a specific purpose/project.

For example, I started way back with only the "Work" workspace where I'd place all the work-related links, but then it got a bit out of hand, so I split it into a dedicated workspace per project.

In Arc I had 35 workspaces and around ~2000 links in total 😅

@geek_1001 But some of my bookmarks are not only for one workspace, they are aligning with more niches :D

@busmark_w_nika yeah, fair point :)
It's a tricky challenge to solve. I was also thinking of adding an API/CLI for AI agents to help organize the bookmarks directly in the app. For example, when you have a bookmark that's related to multiple workspaces, I think it's fine to duplicate it in both workspaces as well

I'm thinking of workspaces more like a "desk for everything I need to work on specific thing"

WOW, good luck with the launch! I wonder how long it took to build it?

@valia_havryliuk Thank you so much Valia! 🙏

In total it took me a little over a week, a few hours per day. Definitely faster than I would have expected 🙂
