SandBlock — advertentieblokkering door SandVPN

Adblock blocks ads and trackers before they are even requested.

WHY IT'S FAST
A static network filtering engine indexes every filter under its most
discriminating token, so out of 120,000+ filters, only a handful are ever
evaluated per request. Average matching latency: ~11 microseconds.

WHAT IT BLOCKS
• Ad and tracker network requests (EasyList, EasyPrivacy, uAssets, Liste FR)
• Ad placeholders, via CSS element hiding
• YouTube video ads, via scriptlets that strip ad metadata from the player
• Tracking parameters in URLs (fbclid, gclid, utm_*, and 120 more)

BUILT NOT TO BREAK SITES
Cosmetic rules are validated before use: any selector able to reach the
document root or match arbitrary elements is rejected. Generic rules are
served on demand, based on the classes actually present in the page,
instead of being dumped wholesale onto every site.

PRIVACY
No accounts, no analytics, no telemetry, no data collection of any kind.
Everything runs locally on your device.
