  • They diverge on capability: Night Eye covers Color analysis, Stay covers Tampermonkey and Violentmonkey compatibility.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Night Eye

  • Can impact browser performance, especially on older or less powerful devices due to color conversion processing
  • Ineffective on web applications with fixed color schemes that cannot be altered
  • Does not work offline or on non-web content
  • Limited customization on websites that have their own built-in dark mode implementation

Stay

  • Apple only. No Chrome, Firefox or Edge build, so it cannot serve a cross-browser workflow.
  • The free tier is deliberately limited, so the practical product is the paid one.
  • Compatibility with Tampermonkey and Violentmonkey scripts is a translation layer rather than the real thing, and a script relying on an unusual GM function may not behave identically.
  • It bundles bookmark sync, downloads and dark mode alongside the script manager, which is more surface area than some people want from an extension with access to every page.
  • A much smaller project than the established managers, so fewer scripts are tested against it.
