Block ads and protect your privacy locally with AdWall X, the ultimate smart ad blocker and DNS firewall!

AdWall X is a powerful, lightweight, and rootless DNS firewall designed to protect your privacy and block ads, trackers, and malicious domains across your entire Android device.

If you are looking for an effective ad blocker that works system-wide without root, AdWall X provides the perfect local adblock solution. Unlike traditional VPNs that route all your internet traffic through external servers, AdWall X operates locally on your device. By setting up a local split-tunnel VPN, it intercepts only DNS queries (UDP port 53). This ensures maximum privacy, zero internet speed drops, and near-zero battery consumption.

Key Features:

🛡️ System-Wide Ad Blocker & Tracker Blocking
Block annoying ads, pop-ups, and background trackers before they even load in your browser or apps. AdWall X matches queries against a massive, optimized local adblock list using an allocation-free suffix match algorithm to instantly block ads and secure your network.

🔒 DNS-over-HTTPS (DoH) Support
Keep your browsing history safe from your ISP and hackers. AdWall X encrypts all your allowed DNS requests using secure, industry-leading DoH providers (like Cloudflare and Google) for secure ad blocking and anonymous browsing.

⚡ High Performance & Battery Friendly
Built on a modern, three-stage asynchronous coroutine pipeline (Reader-Resolver-Writer). It handles thousands of queries seamlessly without bottlenecking, eliminating device heating and battery drain. A smart LRU cache speeds up duplicate requests, making this the fastest local ad blocker available.

🚦 Per-App Firewall Control
Take full control of your apps. You can easily exclude specific apps from DNS filtering or restrict their network access entirely with our intuitive per-app permission manager. Customize your ad blocking rules for each application.

👁️ Live Traffic & Analytics
Monitor your network activity in real-time. View blocked and allowed domains, see which apps are making requests, and manage allowed/blocked domains locally to fine-tune your ad blocker settings.

🛡️ Privacy-First Architecture
All data stays on your device. There are no remote logging servers, no data collection, and no tracking. AdWall X is subscription-free, completely ad-free, and respects your digital footprint.
