Description

StatePeek injects a <style> into the active tab to instantly simulate three rendering states: best-effort dark mode (color inversion), reduced motion (animations and transitions disabled), and high contrast (grayscale + contrast). Handy for a quick visual accessibility and theme check without touching your source. 100% offline, zero telemetry, minimal permissions (activeTab on demand only).

Features

  • Best-effort dark mode toggle (color inversion + re-inversion of images and video)
  • Reduced motion toggle: disables animations, transitions and smooth scroll
  • High contrast toggle: grayscale + increased contrast
  • Toggle off / Reset page: removes every override from the tab
  • State remembered across sessions and re-applied on open
  • 100% offline, no data leaves the browser, minimal permissions (activeTab)

Privacy
