Arivna Shield

Unwanted requests stop before they load.

Every request a page makes passes through Shield, a native engine written in Rust. If a filter matches an ad, a tracker or a known malicious address, the request is never sent.

  • Reads uBlock Origin and Adblock Plus filter syntax, including cosmetic rules, scriptlets, $redirect and $removeparam
  • A per-tab request log shows the filter behind every decision
  • Tap any element to hide it, or switch Shield off for one site

Measured, not claimed

Numbers with a method behind them.

Measured by us on a vivo I2217 with Android 16 and a release build, October 2026.

10.9MB APK download One APK for every supported CPU. The engine itself is about 2 MB per CPU.
33ms Shield time, one page All time spent in Shield for a first page load (BBC, about 75 requests). Later pages: 16 to 22 ms.
0–2% Janky frames Scrolling a news page. Median frame time 8 ms.
275ms Cold start, fastest run Start to first frame was 275 to 380 ms. Faster after Android compiles the app.

In the desktop benchmark, uBlock Origin's engine checks one request about 10% faster than Shield (2.9 vs 3.2 µs); Shield builds about 5× faster and restores from cache about 9× faster. Full method and numbers
