Kosher Browser

Block distracting or inappropriate sites with schedules, a focus timer, password lock, and SafeSearch enforcement.

Kosher Browser turns your browser into a focused, intentional space. Decide what you don't want to see, and it stays out of the way. Blocking • Category presets with 410 ready-made domains — adult content, social, video, news, shopping, gambling. One toggle each, ranked by real traffic rather than listed alphabetically. • Custom blocklist — any domain you choose, subdomains included. • Whitelist mode — block the entire web except sites you explicitly allow. • SafeSearch enforced on Google, Bing and DuckDuckGo. Ads and tracking (optional, off by default) • Ads only — 105 advertising networks blocked, measurement left working, least disruption to sites. • Ads and tracking — a further 45 analytics hosts. • Per-site exceptions for sites you want to support. YouTube (optional, off by default) • Four modes: no limits, block entirely, block Shorts only, or allow only channels you approve. • Approved channels only: add channels such as @nickjr and nothing else will play. Useful for children. • YouTube ad blocking, independent of the mode you choose. Discipline • Focus timer — 15 / 25 / 45 / 60 / 120 minutes or any duration. The countdown survives a browser restart. • Schedule — specific days and time windows, enforced even when categories are off. • Password lock — required to change settings, end focus early, or switch protection off. • Strict mode — locks the off switch itself. Everything else • Custom block page with your own message. • Hebrew and English interface (RTL/LTR), following your browser language by default. • Privacy: nothing leaves your computer. No accounts, no analytics, no servers. The only two features that read anything from a page are the optional YouTube ones, and they compare it on your device and discard it.
