Dark mode for every website. Take care of your eyes, use dark theme for night and daily browsing.

Beautifully dark. Perfectly quiet. Vesper turns every website into a soft, consistent dark theme. No harsh inversions, no flashing white pages, no eye strain. It's a calmer way to browse, day or night. ✦ Five curated color modes Switch the mood of the whole web with one click: • Standard — balanced everyday dark • Dimmed — softer and lower contrast • Midnight — deep, true dark for late nights • Warm — gentle sepia tones that are easy on the eyes • Cool — crisp, slightly blue dark theme ✦ Tune it to any site Fine-tune brightness, contrast, and sepia per website. Enable or disable Vesper on specific sites, automatically sync with your system dark mode, and let Vesper detect sites that are already dark and leave them untouched. ✦ Distraction-free Reading mode (Pro) Strip away clutter, ads, and sidebars for clean, focused reading on articles and long-form pages. ✦ Private by design Vesper runs 100% locally. No account, no sign-up, no tracking, and no data ever leaves your browser. Tip: please disable similar dark-mode extensions to avoid conflicts.
