Tabs, tantrums, and tidy vibes
Show HN: Arcmark – macOS bookmark manager that attaches to browser as sidebar
Arc-style bookmarks for every browser—and the comments are chaos
TLDR: Arcmark brings Arc-style bookmark sidebars to any Mac browser and keeps everything local on your machine, even importing Arc setups. Commenters split between loving a standalone manager, joking they never revisit bookmarks, and requesting sync and polish—plus the obligatory “just use Zen Browser” drive-by debate.
Meet Arcmark, a Mac app that sticks a bookmark sidebar onto whatever browser you’re using, copying the tidy vibe of the Arc browser without forcing you to actually use Arc. It’s local-first (saved to one file on your Mac), lets you color-code workspaces, drag folders around, and even import your Arc pinned tabs. It needs accessibility permissions to latch onto your browser window, but it can run as a normal floating panel too.
But the real show is the comments. One camp is cheering: think password manager vibes for bookmarks—standalone, powerful, not tied to a single browser. “Browsers should browse, apps should organize,” sums up the mood. The other camp? Shrugging. One self-aware skeptic joked they treat bookmarks as a “write once read never” graveyard, while tab hoarders are gleefully plotting their great tab exodus into neatly labeled folders.
Then the plot twist: someone drops the “just use Zen Browser” line, sparking the classic “new app vs. new workflow” scuffle. Feature requests flew in hot: cloud sync for that local file (WebDAV, anyone?), better guidance on the “Always on Top” toggle, and even dreams of browsers exposing better hooks so external managers can slot in cleanly. It’s half productivity revolution, half group therapy for people with 300 open tabs—and everyone’s invited.
