who it's for

Who Arcmark is for#

Mac users leaving Arc

Arcmark fits users who like Arc's sidebar organization but want to use Chrome, Safari, Brave, or another browser.

Skip if

You need bookmark sync across Windows, Linux, and mobile devices.

Local-first bookmark organization

The local JSON storage model helps users keep bookmark data inspectable and outside a hosted bookmark service.

Skip if

You want team collaboration, hosted sync, or browser-extension based sharing.

the problem

The problem it solves#

Browser bookmarks are usually trapped inside one browser's sidebar and organization model. That becomes frustrating when a user wants Arc-style workspace organization without staying inside Arc or manually duplicating bookmarks across browsers.

Power users also need bookmarks to stay local and searchable. A simple browser folder tree can break down when links need to be grouped by workspace, moved quickly, and accessed beside whichever browser is active.

how Arcmark solves it

How it solves it#

Browser-attached sidebar

Arcmark can float alongside supported browser windows and follow them across spaces while still offering a standalone window mode.

Workspace organization

Users can organize bookmarks into multiple workspaces with custom colors, nested folders, and drag-and-drop movement.

Local JSON storage

The README says bookmarks are stored in a single local JSON file under the user's Application Support directory.

strengths · trade-offs

Strengths and trade-offs#

Strengths

  • Browser-independent organizationArcmark is useful for people who want Arc-like sidebar organization while keeping freedom to use another browser.
  • Native macOS feelBecause it is built with Swift and AppKit, Arcmark can behave like a focused local macOS utility rather than a web app.

Trade-offs

  • -Mac-only utilityArcmark targets macOS and requires accessibility permissions for browser attachment. Cross-platform teams should not treat it as a shared bookmark platform.
