NetGuard Alternatives for Android Firewalls

NetGuard is one of the best-known Android no-root firewalls. It is mature, open source, and trusted by many privacy-minded users. If you are searching for NetGuard alternatives, the right answer depends on why you want an alternative.

Do you want something simpler? Choose Isolate. Do you want DNS filtering and tracker lists? Choose RethinkDNS. Do you want tracker visibility? Choose TrackerControl. Do you have root? Choose AFWall+. Do you want a basic Play Store internet blocker? Consider Net Blocker, Internet Blocker No Root, or NoNet.

1. Isolate

Isolate is the best NetGuard alternative for people who do not actually want a full firewall dashboard. Many users searching for NetGuard alternatives are trying to solve a smaller problem: block TikTok while studying, stop games from using mobile data, keep YouTube offline during work, or prevent selected apps from connecting in the background.

Isolate is built for that kind of control. It blocks WiFi, mobile data, or both per app, and it includes focus modes for work, study, sleep, and custom routines.

Pros

• Easier than NetGuard for everyday app blocking.
• No root required.
• Direct WiFi and mobile data blocking per app.
• Built-in focus modes.
• Play Store listing says no data collected and no data shared.
• Good for non-technical users.

Cons

• Not open source in the same way NetGuard is.
• Not as advanced for logs, per-address rules, and deeper firewall analysis.
• Smaller user base and shorter history.

Pricing and features

Isolate is listed with in-app purchases and described as ad-free with no subscriptions. Its core value is simple per-app blocking plus focus workflows.

Ideal users

Choose Isolate if NetGuard feels heavier than the problem you are trying to solve.

2. NetGuard

Before replacing NetGuard, it is worth saying where it still wins. NetGuard is a serious no-root firewall. It can allow or deny WiFi and mobile data per app, it is open source, and it has a long reputation.

Pros

• Mature no-root firewall.
• Open source.
• Strong app-level WiFi and mobile data rules.
• Good for privacy-conscious users.
• Optional pro features for logging and deeper control.

Cons

• More technical than focus-first blockers.
• Interface and settings may feel like a firewall rather than a productivity tool.
• Android VPNService limitations apply.

Pricing and features

NetGuard is free and open source with optional pro features. Its official feature list includes app-level allow and deny rules, IPv4/IPv6 TCP/UDP support, optional network usage logging, per-address blocking, access notifications, and more.

Ideal users

NetGuard remains ideal for users who want more control than a simple blocker.

3. RethinkDNS

RethinkDNS is the best NetGuard alternative if your reason for switching is "I want more privacy visibility."

It combines firewall control with DNS filtering, blocklists, app logs, DNS logs, anti-censorship tooling, and optional VPN-style routing features.

Pros

• More complete privacy toolkit than most basic blockers.
• Blocks ads, trackers, malware, and other domains through DNS blocklists.
• Shows app connection activity.
• Supports advanced firewall rules.
• Good for people who want to learn what their apps are doing.

Cons

• More complex than NetGuard for some users.
• More product surface than needed for basic app blocking.
• Paid RPN features may be irrelevant if you only need a local firewall.

Pricing and features

RethinkDNS has free DNS and firewall app features. Its FAQ lists RPN plans starting at $1.75 per month as of 2026.

Ideal users

Choose RethinkDNS if you want firewall plus DNS filtering, not just app blocking.

4. TrackerControl

TrackerControl is a NetGuard alternative for people who care most about hidden tracking inside apps.

Pros

• Monitors app tracking behavior.
• Blocks trackers and ads.
• Uses Android VPN functionality locally by default.
• Good educational privacy tool.
• No root required.

Cons

• More tracker-focused than firewall-focused.
• Not the fastest path for simple "block this app from internet" use cases.
• Feature differences can exist between Play Store and F-Droid/GitHub versions.

Pricing and features

TrackerControl is available through Google Play, F-Droid, and GitHub depending on the version. It focuses on tracker analysis, granular blocking, ad blocking, and optional secure DNS or remote VPN routing.

Ideal users

Choose TrackerControl if you want to see and reduce tracking rather than build a general firewall policy.

5. AFWall+

AFWall+ is not a no-root alternative. It is a root-required alternative. That makes it wrong for most users and excellent for a specific group.

Pros

• Root-level iptables firewall.
• Strong for advanced Android users.
• Supports profiles, Tasker, roaming, LAN, VPN, tethering, IPv4, and IPv6.
• Open source.

Cons

• Root is required.
• Not beginner-friendly.
• Rooting can create compatibility and security tradeoffs.

Pricing and features

AFWall+ is available on Google Play, with donation and unlocker apps also listed by the developer.

Ideal users

Choose AFWall+ only if you already use a rooted Android device and understand the risks.

6. Net Blocker

Net Blocker is a simpler Play Store alternative. It blocks selected apps from accessing the internet without root.

Pros

• Simple app-level blocking.
• No root required.
• Large download base.
• Listing says no data collected.

Cons

• Listed with ads and in-app purchases.
• Not as advanced as NetGuard.
• Less privacy-analysis depth than RethinkDNS or TrackerControl.

Pricing and features

Net Blocker is free to install with ads and in-app purchases. It uses a local VPN interface to block app traffic.

Ideal users

Choose Net Blocker if you want a basic blocker and do not need NetGuard's depth.

7. NoNet

NoNet is a focus-friendly alternative that is closer to Isolate than to NetGuard.

Pros

• Easy for beginners.
• Includes a custom productivity timer.
• No root required.
• Listing says no data collected and no external servers for traffic.

Cons

• Smaller install base.
• Listed with ads and in-app purchases.

Ideal users

Choose NoNet if you want temporary app blocking sessions more than firewall administration.

How to choose a NetGuard alternative

If NetGuard is too complex, choose Isolate.

If NetGuard is not broad enough for DNS and tracker filtering, choose RethinkDNS.

If NetGuard does not show the tracking story you want, choose TrackerControl.

If NetGuard is not low-level enough and you already have root, choose AFWall+.

If you only want a basic Play Store blocker, choose Net Blocker, Internet Blocker No Root, or NoNet.
