Scrolodex – macOS Window Switcher

A lightweight macOS utility that lets you quickly switch between open windows by holding a hotkey and scrolling. Solves the friction of alt-tabbing or using Mission Control. Target users are power users and developers who want faster window navigation.

macOS power users have been vocal on forums like Hacker News and Reddit about frustration with native window management, and the success of tools like Raycast and Rectangle shows real willingness to pay for focused utilities that fill gaps Apple leaves open. The closest competitor is Witch by Many Tricks, which has held this niche for years and has a loyal user base, meaning the switching cost problem is real but so is the entrenched alternative. At $500–2k/mo, the revenue band is plausible for a one-time purchase or low-cost subscription on the Mac App Store or Gumroad, but it likely represents a ceiling rather than a floor — the addressable pool of users willing to pay for a scroll-based switcher specifically is narrow. The biggest risk is that this is a feature, not a product: Apple could ship something similar in a macOS update, or an existing tool like Hammerspoon or BetterTouchTool could replicate the behavior in a weekend config, killing willingness to pay entirely.
