AI Analysis

●●SolidCozySlick

Live window previews on hover beat the stock app-icon beauty pageant.

Strengths
  • ScreenCaptureKit integration renders real-time thumbnails without opening Mission Control.
  • Widgets occupy dead Dock space instead of cluttering the menu bar.
  • Cmd+Tab replacement shows actual windows, not just app icons.
Weaknesses
  • Requires Screen Recording permission, which scares privacy-conscious users.
  • Limited to macOS; Windows and Linux users get nothing.

Post Description

There's dead space on both sides of the Dock. Nobody uses it. So I stuck widgets there. Music with synced lyrics (Spotify + Apple Music), calendar, weather, a Pomodoro timer, system stats. They sit in little glass panels and stay out of the way until you look down.

The other thing: hover a Dock icon and macOS shows you the app name. Thanks, I forgot what Safari was called. Docktor replaces that with live thumbnails of every window for that app. Click one, you're there. Same idea powers a Cmd+Tab replacement. Actual window previews instead of a beauty pageant of app icons.

I spent a lot of time matching the system look. Same blur radii, same animation timing. It should feel like part of the Dock, not something bolted on.

Native Swift. No Electron, no account, no telemetry.

First beta goes out next week. Looking for testers: https://petercsauer.github.io/docktor-releases/

Testers get lifetime access free. After that it'll be $10 one-time for 20 seats, 60-day trial. Share it with your whole family or team. No subscription, ever.

I'm also building a full Dock replacement for the Liquid Glass haters. Not shipped yet but it's next.
