Coming from GlassWire
NetCage can’t be installed today. It has no store listing and no public download, so this page ends without an install step. It covers how the two apps differ and which pages here to read first.
How does GlassWire differ from NetCage?
GlassWire starts with the question of which app is using your data, with graphs and limit alerts, and blocking comes after that. NetCage starts from the point where you already know. Its optional data totals come from Android’s own accounting, per user ID, and they aren’t a usage dashboard.
Both use Android’s VPN slot, and Android allows one VPN at a time, so GlassWire’s firewall and NetCage can’t run together.
Choose GlassWire if your first question is which app is eating your data plan, and blocking is the second step.
Choose NetCage if you already know which app should be offline and want it caged in one switch, without a usage dashboard in the way.
What should I read first?
NetCage imports nothing from GlassWire, so there’s no settings file to bring across. You’d choose your apps again.
- Caging apps: the switch, and where the data totals appear.
- Why can data totals cover several apps?: how much those totals can tell you.
- How it works: what the tunnel does with a caged app’s packets.
What does each one state?
