Bration-Extension

Your Screen. Your Data. Everything Else — Blocked.

An open-source ad, tracker, and popup blocker for browsers, powered by Brave's own adblock-rust engine, compiled to Web Assembly. No accounts. No telemetry. No data ever leaves your machine.

---

✨ Features

• Network-level blocking — a stacked filter list (EasyList, EasyPrivacy, AdGuard Base, AdGuard Annoyances, plus dedicated scam/malvertising-redirect lists) checked against every request via a Rust engine compiled to WebAssembly
• Cosmetic filtering — hides ad containers and sponsored banners that load as page content, not just blockable network requests
• Popup blocking — automatically closes ad-triggered popup tabs
• Forced-redirect protection — stops cross-site scripts from hijacking your navigation to scam pages
• Per-site control — turn blocking off for one specific site without affecting any other tab or domain
• Dashboard — a WhatsApp-style view of every domain you've visited (30-day history), with a full breakdown of exactly what got blocked and where

🔒 Privacy

Everything is stored locally via your browser's own storage. Nothing is sent to any external server, no account is required, and the extension's manifest explicitly declares zero data collection. Privacy policy

The Rust core lives in bration-extension-core/ and is compiled automatically via GitHub Actions on every push — see .github/workflows/build-wasm.yml.

🛠️ Building from source

Requires Rust + wasm-pack

cd bration-extension-core

wasm-pack build --target web --release

This produces the same wasm-core/ output bundled with the extension. The build also runs automatically on every push via GitHub Actions — no local setup required if you just want to verify the build.
