5 Best NetGuard Alternatives for Android (2026)

NetGuard is the most popular no-root firewall on Android, and for good reason: it is simple, open source, and free. But it is not the only option, and for some people it is not even the best one. NetGuard has real limits — no DNS-level ad blocking, traffic logging locked behind the paid Pro version, and no way to share Android's single VPN slot with a real VPN app.

If any of that bothers you, the apps below are worth a look. Every alternative here is free, actively maintained, and verified on the live Google Play Store on October 8, 2026. They cover every reason you might leave NetGuard: stronger privacy, rooted-phone power, visual data monitoring, and tracker detective work.

Quick Comparison

1. RethinkDNS — Best All-Round Alternative

If you want everything NetGuard does plus a lot more, RethinkDNS is the closest thing to an upgrade. It is a no-root firewall like NetGuard, but it also blocks ads and trackers at the DNS level using over 190 blocklists, encrypts your DNS queries, and includes anti-censorship features and WireGuard VPN support.

The practical difference: where NetGuard can only switch a whole app's internet on or off, RethinkDNS can strip the advertising and tracking domains out of an app while letting the useful parts keep working. Its connection monitor shows you exactly which servers each app contacts, in near real time. Users who switched from NetGuard call it "a premium NetGuard for free."

The trade-offs are a steeper learning curve and higher battery use (roughly 5 to 10 percent per day in full firewall mode, versus NetGuard's very light footprint). If you want the full head-to-head, read our RethinkDNS vs NetGuard comparison.

Choose it if: you want firewall control plus ad-blocking, encrypted DNS, and VPN features in one free app.
Skip it if: you just want a dead-simple on/off switch per app.

2. AFWall+ — Best for Rooted Phones

If your phone is rooted, AFWall+ is in a different league from every no-root firewall. Instead of borrowing Android's VPN slot, it controls traffic at the system level using Linux iptables — the same technology that protects servers. That means deeper, more reliable rules, and it keeps working even when a separate VPN app is active.

AFWall+ supports per-app rules across Wi-Fi, mobile data, roaming, VPN, tethering, and LAN, with multiple profiles (home, work, public), Tasker automation, import and export of rules, password protection, and boot-time rule application. It is open source under GPL-3.0 and has been maintained since the DroidWall days.

The catch is absolute: it does not work at all without root. Rooting affects security, updates, and banking apps, so this pick is only for people who have already rooted and know why.

Choose it if: your phone is rooted and you want the deepest firewall control on Android.
Skip it if: your phone is not rooted — look at the other four instead.

3. InternetGuard — Best for Beginners

InternetGuard is the simplest way to get NetGuard-style protection. Per-app allow and block for Wi-Fi and mobile data, screen-on rules, block when roaming, new-app notifications, and a traffic log — all free and open source, with no tracking.

One important warning: there are several copycat apps on the Play Store using the InternetGuard name, and some of them contain ads. The original, open-source version is published by SheikhSoft (package eu.sheikhsoft.internetguard). Always check the developer name before installing.

InternetGuard is less powerful than NetGuard's Pro tier or RethinkDNS — no DNS filtering, no per-domain rules — but for a first firewall it is hard to beat on simplicity.

Choose it if: you are new to firewalls and want simple, free protection.
Skip it if: you need domain-level blocking or traffic analysis.

4. GlassWire — Best for Data Monitoring

GlassWire approaches the problem from the other direction: instead of starting with blocking, it starts with showing you where your data goes. Beautiful live graphs reveal which apps are using Wi-Fi or mobile data right now, alerts warn you before you hit your data cap, and you get notified the moment a new app accesses the network.

Once you see the picture, GlassWire's mobile firewall lets you block badly behaving apps, with separate profiles for mobile data and Wi-Fi. Your data never leaves the phone, and there are no ads. With over 20 million downloads across its Windows and Android apps, it is the most mainstream name on this list.

GlassWire is less of a hardcore firewall than NetGuard — its rule system is simpler — but if your main question is "which app is eating my data," nothing visualizes the answer better.

Choose it if: you want to see and understand your data usage before deciding what to block.
Skip it if: you need advanced DNS, domain, or system-level rules.

5. TrackerControl — Best Tracker Detective

TrackerControl is built for one job: exposing the hidden tracking inside your apps. It monitors network traffic locally on your device and shows you which companies receive your data, for what purpose (advertising, analytics, and so on), and from which countries. It detects tracker libraries inside app code using Exodus Privacy signatures, and it even teaches you about your data rights under laws like the GDPR.

Here is a fun fact: TrackerControl's network analysis is built on NetGuard's own code. And here is the catch you must know: the Play Store version ("Slim") is study-only — it shows you the trackers but the full blocking features live in the Full version, available from F-Droid or GitHub. If you install from Play expecting a blocker, you will be disappointed; if you want the detective work, it is excellent.

Choose it if: you want to see exactly who tracks you and why.
Skip it if: you want simple per-app blocking — get the F-Droid Full build instead.

What About NoRoot Firewall?

You may see NoRoot Firewall recommended in older articles. Do not install it. It has been removed from the Google Play Store, has not been updated in years, and never gained IPv6 support, which breaks it on modern mobile networks. RethinkDNS covers the same no-root use case and is actively developed.

How to Choose

Start with your situation, not the feature list. Not rooted and want it simple? InternetGuard or NetGuard itself. Want ad-blocking and maximum privacy in one app? RethinkDNS. Rooted and want total control? AFWall+. Mostly worried about data usage? GlassWire. Curious about who tracks you? TrackerControl.

Remember the one hard rule of Android firewalls: only one app can use the VPN slot at a time. Pick one firewall, give it a week, and judge it on your real usage. And if you are comparing privacy tools more broadly, our WhatsApp vs Briar and SimpleX vs Session guides follow the same "how deep do you want to go" logic.

Switching Firewalls Without Breaking Your Phone

Moving from NetGuard to a new firewall is safe if you do it in the right order. First, turn off NetGuard and uninstall it — or at least disable its VPN — before starting the new app, so the two never fight over Android's single VPN slot. Second, do not import old rules blindly; each app organizes rules differently, and a bad import can silently block things like push notifications or app updates.

Third, start permissive. Block only the apps you are sure about — games, calculators, and utilities that have no business being online — and watch the new firewall's log for a few days before tightening rules on messaging or banking apps. If something stops working, the log will show you exactly which connection was blocked, and one tap restores it. Most "my firewall broke my phone" stories come from blocking system services on day one, so leave Google Play Services and system apps alone until you understand what each one does.

Frequently Asked Questions

What is the best alternative to NetGuard?

RethinkDNS is the closest all-round alternative — it adds DNS ad-blocking, anti-censorship, and WireGuard VPN to the same no-root firewall idea. For rooted phones, AFWall+ gives deeper system-level control.

Is there a free firewall app like NetGuard?

Yes. RethinkDNS, AFWall+, InternetGuard, GlassWire, and TrackerControl are all free. NetGuard itself is also free — only its Pro features like the traffic log are paid.

Why would I switch from NetGuard to something else?

Common reasons: you want DNS-level ad and tracker blocking (RethinkDNS), you have a rooted phone and want system-level rules (AFWall+), you want visual data monitoring (GlassWire), or you want to see exactly which trackers your apps contact (TrackerControl).

Can I run two firewall apps at the same time?

No. Android allows only one app to use the VPN service at a time, and no-root firewalls all use it. Running two will cause conflicts — pick one.

Is NoRoot Firewall still safe to use?

No. NoRoot Firewall has been removed from the Google Play Store and has not been updated in years. Switch to NetGuard, RethinkDNS, or another maintained app on this list.

Which firewall app works on a rooted phone?

AFWall+ is the best choice for rooted phones. It uses Linux iptables at the system level, works even alongside a VPN, and supports profiles, Tasker automation, and per-network-type rules.
