Questions

Answers, up front.

What is TopShelf?

TopShelf is a macOS menu bar utility that floats any website or built-in mini app as an always-on-top window on your Mac. Built by ApoioLabs.

Floats always-on-top
Websites (any URL) and six built-in mini apps sit above every other window.
Quick launch
Installed Mac apps launch from the menu bar; TopShelf brings their existing window forward.
How does TopShelf work?

TopShelf lives in your Mac menu bar and turns any website or built-in mini app into a floating always-on-top window with one click.

  1. 1Click the TopShelf icon in your menu bar.
  2. 2Paste a URL, or pick one of the six built-in mini apps (calculator, notes, to-do, pomodoro, color picker, password generator).
  3. 3TopShelf opens a small resizable window that stays above every other window, even across spaces and full-screen apps.

Move it, resize it, snap it to a corner, or dismiss it from the menu bar at any time. Pinned installed Mac apps launch straight from the menu bar (existing window brought forward, not forced always-on-top).

How much does TopShelf cost?

TopShelf is a one-time purchase with free updates for life. Buy the current version on the Mac App Store. A free trial (an older, time-limited version) is available on Gumroad if you'd like to try TopShelf first.

One-time purchaseLifetime licenseFree updates foreverNo subscriptionNo account

See the Mac App Store listing for current pricing.

Is there a free trial?
Yes, on Gumroad. Time-limited.

A free trial of TopShelf is available on Gumroad. It's an older version of the app you can download and use for a limited time. No account or credit card needed to start.

When the trial expires, you'll be prompted for a license code to keep using it. To purchase the current version of TopShelf with free lifetime updates, get it on the Mac App Store.

Does TopShelf work with ChatGPT, Claude, Spotify, Slack, or any specific app?
Yes. Any web-based service floats as an always-on-top window.

TopShelf works with any website. Anything with a URL becomes a floating always-on-top window on macOS.

Music
Spotify Web PlayerApple Music webYouTube

Native Mac apps like the Spotify desktop app or Slack desktop app can also be pinned to the menu bar for quick launching, though those windows are brought forward rather than floated always-on-top. For always-on-top behavior with those services, pin the web version of the app instead.

Does TopShelf collect data?
No. TopShelf collects zero personal data.

All TopShelf settings are stored locally on your Mac. This is by design. TopShelf is built on a Privacy by Design principle.

  • Analytics
  • Telemetry
  • Third-party tracking
  • User accounts
  • Credit card details
Where is my mini app data (notes, tasks) saved?
Locally on your Mac. No sync, no account.

All TopShelf mini app data is stored on-device using macOS's standard preferences system (UserDefaults) inside the app's sandboxed container. Nothing leaves your Mac, there's no cloud sync, and no account is required.

  • Notes: your notes and grouping preference.
  • To-Do List: your tasks, sort order, and grouping preference.
  • Password Generator: your generator settings and a capped local history of generated passwords.
  • Color Picker: your last-picked color and a capped local color history.
  • Calculator: your scientific-mode preference.
  • Pomodoro: no persistent data (session state only, resets when you close the window).

If you delete TopShelf from your Applications folder, macOS removes the sandboxed container and everything in it goes with the app. Your notes, tasks, and histories included.

What macOS versions does TopShelf support?

TopShelf is a native macOS menu bar utility, not a cross-platform Electron wrapper. For the exact minimum macOS version requirement, check the Mac App Store listing, which always reflects the current supported OS.

  • Modern versions of macOS
  • Apple Silicon (M1, M2, M3, M4)
  • Intel Macs
  • Windows
  • Linux
How is TopShelf different from Rectangle, Stay, or built-in macOS window management?

TopShelf solves a different problem than window managers like Rectangle, Magnet, Moom, or Stay. macOS itself does not natively offer an always-on-top mode for arbitrary websites or web apps. TopShelf is purpose-built for that single job on Mac.

Float websites always-on-top

Where can I download TopShelf?

TopShelf for macOS is available on two channels. The Mac App Store is where you buy the current version with free lifetime updates. Gumroad hosts the free trial (an older, time-limited version).

Mac App Store (buy)
Purchase the current version of TopShelf with free lifetime updates and automatic App Store updates. Open listing.
Gumroad (free trial)
