Kosher Browser od kosher browser

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.
• 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.
• 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 restart.
• Schedule — specific days and time windows, enforced even when categories are off.
• Password lock, and strict mode which locks the off switch itself.

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.
