Stackly Workspaces
Organize your browser tabs
Only for Mac
$2.99
Mac
Turn messy windows into clear, local-first workspaces you can reopen, inspect, merge and sync across browsers on your Mac.
Stackly turns your tabs into clear, local-first workspaces that stay on your Mac.
Instead of keeping every tab mixed inside one endless window, create a stack for each project, client, topic or routine. Each stack becomes a context you can resume later with its tabs, note, recent activity and quick actions.
Built for Safari on Mac, Stackly helps you switch contexts without losing the thread: client work, product research, admin, travel planning, reading, side projects and more.
Main features:
Create visual stacks with a name, color and icon.
Automatically save the tabs of the active stack.
Resume a context from the full manager or the Safari popup.
Inspect the tabs inside a stack before opening it.
Move tabs between stacks.
Merge related stacks and clean duplicate tabs.
Add a note and follow the timeline of each context.
Sync locally between Safari, Chrome and Firefox on the same Mac.
Import and export your data as JSON.
Switch between light and dark mode.
Stackly is local-first:
No account required.
No tracking.
No forced cloud.
Your data stays on your machine.
Stackly is made for people who juggle multiple projects and want to recover the right mental workspace quickly, without adopting a heavy productivity system.
