Canvas-aware Sheets
The grid, headers and formula bar all go dark together. If a sheet is already dark (say, painted by a dark add-on), Dark Browser detects it and leaves it alone — no accidental double-flip back to white.
Built for people who live in Google Docs & Sheets
Your spreadsheets deserve a night shift.
Dark Browser turns every website dark the instant it loads — and it's the rare dark mode that actually gets Google Docs and Sheets right: crisp cells, readable text, charts and images in their true colors, and not a single blinding white flash.

Watch it in action
See Dark Browser in under a minute.
From a blinding white spreadsheet to a calm, readable night theme — with one click.
Google Workspace, done right
Most dark modes break Sheets.
Dark Browser was engineered for it.
Google Sheets draws its grid on a <canvas>, and Docs mixes canvas, iframes and live comments.
Generic CSS tricks miss half of it. Dark Browser covers the whole page — every frame, every canvas — in one pass.
Flip the switch and see for yourself.

🖼️
True-color media
Photos, videos, embedded images and background images are restored to their real colors. Your logos stay on-brand and your charts stay readable.
🪟
Every frame covered
Docs comments, add-on sidebars, dialogs and embedded frames all follow the same theme — no glowing white panels sneaking in from the side.
Quality & performance
Light on your CPU. Easy on your eyes.
Big spreadsheets are heavy enough. Dark Browser is built so you never feel it running.
0ms
White flash
Runs at document_start, before the page paints. Open a Doc at midnight without squinting.
1
GPU filter per page
One hardware-accelerated filter on the page root instead of rewriting thousands of styles, so long sheets keep scrolling smoothly.
256
Pixels per canvas check
Canvas detection samples a tiny 16×16 copy — it never touches the page's own canvas, so Sheets keeps rendering at full speed.

Work on hidden tabs
Background tabs pause scanning entirely. Twenty Sheets open? Only the one you're looking at does anything.

Questions
Good to know
Does it really work in Google Sheets and Google Docs?
Yes — that's what it was tuned for. Sheets' canvas grid, the toolbar, sidebars, comment threads and dialogs all go dark together, and already-dark canvases are detected so they're never flipped back to light.
Will my images, charts and videos look weird?
No. Photos, videos, embeds and background images are restored to their natural colors, so charts, logos and screenshots look exactly as intended.
Does it slow down my browser?
Dark Browser applies a single GPU-accelerated filter per page rather than rewriting styles element by element, and it does nothing at all on background tabs. Large spreadsheets stay smooth.
What does it do with my data?
Nothing. There are no analytics and no browsing data leaves your computer. Your settings are stored in Chrome; the only network request is verifying your license key with Gumroad.
Can I keep some sites light?
Absolutely. Exclude any domain with one click, or switch to "Selected Domain" mode and turn dark mode on only where you want it.
Where doesn't it run?
Chrome doesn't allow extensions on its own pages (like chrome:// settings and the Chrome Web Store). Everywhere else, you're covered.
