SiteTuner — Boost any website's look

Hide clutter with one click, recolor and refont any site, and keep your tweaks per domain. Built for people who miss Arc Boosts.

SiteTuner lets you make any website look the way you want — and remembers it for that site. • Zap: click any element (banners, sidebars, pop-up bars) to hide it on that site for good. Bring it back with one click. • Look: shift colors, change saturation, zoom, switch fonts, or flip a site to dark mode. Photos and videos keep their natural colors. • Custom CSS: write your own CSS for a single site. • All sites: see every site you changed, delete, and export/import your setup as JSON. Built for people who miss Arc Boosts after Arc's shutdown. SiteTuner is an independent project by tanemaki and is not affiliated with The Browser Company or Arc. Privacy: your settings stay in your browser (chrome.storage.local). No analytics, no tracking, no data leaves your device. Permissions: SiteTuner only works on the tab you open it on. If you want a site's changes applied on every visit, press "Keep on <site>" and Chrome will ask to allow SiteTuner on that one site. Free. A paid Pro version may be added later; any payment would be handled by ExtensionPay/Stripe and clearly marked before you pay.
