AdAway vs Quad9 Connect
Side-by-side comparison of two open source alternatives
AdAway
A Free and Open Source ad blocker for Android. The application is available for rooted and non-rooted devices. Using rooted device, the application update your system hosts file that contains a list of mappings between host names and IP addresses. Using non-rooted device, the application use the VPN feature to block outgoing connections to ads and trackers. So when an app requests an ad or a tracker from a host in that file, this request is redirected to the local IP 127.0.0.1, which does nothing. You can download predefined ads and blocker lists as hosts files from within the app to incorporate. It is also possible to use your own files and to add certain hosts to allowed and blocked lists. There are options to run a local web server to respond to blocked host names and to direct requests to the IP address of your choosing instead.
Quad9 Connect
Quad9 Connect is an Android and ChromeOS app that sends your DNS queries to Quad9's secure, private, open recursive DNS service. Quad9 Connect adds additional functionality and features compared to using Android's Private DNS feature to utilize encrypted DNS or configured Quad9 in Chrome on ChromeOS. The application creates a split VPN tunnel with Android API "VpnService" to configure an alternate DNS server on Android and ChromeOS. ## Features - DNS over TLS or DNS over UDP - DNS Query Log - Trusted Networks - Blocked Query Notifications - Local Domains - Excluded Applications
