DarkMySite is a game-changer for WordPress, offering a sleek, "set it and forget it" solution that instantly modernizes any layout with AI-powered color inversion. The performance optimization is impressive, keeping the plugin lightweight without dragging down my Core Web Vitals. However, it’s not without minor flaws; the learning curve for custom CSS overrides can be steep if the AI misses a specific element, and I’ve noticed occasional glitches with certain third-party slider plugins that require manual tweaking. Despite these small hurdles, the ability to replace images specifically for dark mode and the professional floating switch designs make it an incredible value, especially if you grabbed the AppSumo lifetime deal. It is easily the most polished dark mode tool available in 2026.
