So first, the one-liner: Firezone is an open-source (Apache 2.0) zero-trust access platform built entirely on WireGuard. It gives teams resource-level access control with default-deny policies, SSO sync from Google Workspace or Microsoft Entra ID, and NAT hole-punching. You self-host it on a cheap VPS, or go with their managed cloud tier. Either way, the same Gateways work in both modes — so migrating later doesn’t hurt.

Architecture: WireGuard Under the Hood

Firezone runs on WireGuard at the protocol level. That alone puts it ahead of OpenVPN-based solutions on raw throughput — WireGuard’s kernel-level implementation uses Curve25519 and ChaCha20Poly1305, and third-party benchmarks consistently measure 3-4x faster transfers on the same hardware. So you’re not sacrificing speed for the zero-trust model. For a deeper look at setting up WireGuard on various platforms, check out our WireGuard setup guide.

But how does it actually compare to the other players in this space?

Deploying Firezone: 15 Minutes on a Cheap VPS

I deployed Firezone on a DigitalOcean Droplet — the $6/month basic plan, which is plenty for the Portal component. The official docs recommend Docker Compose, and it lived up to that. From SSH to first client connection: about 15 minutes. If you prefer Vultr, their $3.50/month shared CPU instance handles it just as well.

The architecture splits into two parts: the Portal (Elixir-based admin dashboard) and Gateways (Rust-based WireGuard routers). So you run the Portal on a VPS, then deploy Gateways on your network segments — office, cloud VPC, remote worker endpoints. The Portal manages users, policies, and device assignments through a web UI.

Still, the real surprise was the NAT hole-punching. I set up a Gateway behind a residential connection with carrier-grade NAT — no static IP, no port forwarding. Yet Firezone still established a direct WireGuard tunnel without opening any inbound ports. For teams with remote workers on unpredictable networks, that’s a practical advantage you don’t get from a traditional VPN server.

Firezone Pricing: Free Tier vs Paid Plans

So the Starter plan is genuinely useful: up to 6 users, unlimited devices per user, and all core features including SSO. For a startup or a small dev team, that’s it — no feature gating. The Team tier at $5/user/month ($4.16 billed annually) adds priority support and SOC 2 compliance reports. Compared to Tailscale’s $6/user/month, the difference is marginal at the cloud tier — but the self-hosted option changes the math entirely.

Even on a $6 DigitalOcean VPS or a $3.50 Vultr instance, a 10-person team running self-hosted Firezone pays effectively $0.60 per user per month. And that’s a 90% saving versus any cloud-tier competitor. For comparison, check out our breakdown of ProtonVPN vs Mullvad pricing to see how traditional VPNs stack up.

What to Watch Out For

Self-hosting Firezone means you own the maintenance. The Docker setup is clean — the team pushes regular releases on their active GitHub repo (8,700+ stars, 10,400+ commits) — but you’ll still handle updates, backups, and uptime monitoring yourself. So it’s not zero-ops.

The admin dashboard is snappy (Elixir’s LiveView handles real-time updates well), but it’s not as polished as Tailscale’s. And bulk user import workflows are less refined — the documentation assumes DevOps familiarity. So if your team doesn’t have someone comfortable with Docker and Linux, the cloud tier is the safer call.

Bottom Line

Firezone fills a real gap: it’s the only major zero-trust access platform that’s fully open-source, self-hostable, and backed by a managed cloud tier. For sysadmins and team leads looking to replace a legacy VPN or cut Tailscale costs at scale, it deserves a serious look. The WireGuard backend means no performance compromises, and the free self-hosted tier covers small teams with no feature gating.

But — it demands more hands-on care than plug-and-play alternatives. Teams with DevOps muscle will love the flexibility. For everyone else, the cloud tier at $5/user/month is the safer bet.

Here’s the short answer: BlockAds is a free, open-source Magisk module that blocks ads at the system level without running a background app. And it uses curated host files from OISD and 1Hosts to catch ads and trackers before they even reach your phone.

What Is BlockAds?

BlockAds (github.com/pantsufan/BlockAds) is a Magisk module — over 200 GitHub stars, monthly updates — that injects ad-blocking host rules directly into the Android system. Unlike VPN-based blockers, there’s no persistent notification, no connection speed impact, and no battery overhead.

The module merges two well-maintained blocklists:

I grabbed the ZIP from the releases page — 3.5MB, took maybe 10 seconds to download. Flashed it in Magisk Manager, hit reboot, and that was the entire setup. And the real test: opening a few apps I knew were ad-heavy — a news app that normally shows two full-screen interstitials per session showed none. Second was a free game. Ad banner where the bottom ad usually sits? Gone. Zero config, zero tweaking.

Still, there’s a trade-off: BlockAds requires Magisk — your phone needs to be rooted. That’s a non-starter for a lot of users. But if you’re already running Magisk, it’s one of the cleanest ad-blocking solutions available.

How BlockAds Works

Once installed through Magisk Manager, BlockAds writes a massive hosts file to /system/etc/hosts. Every time an app tries to connect to an ad server, the request hits 127.0.0.1 and dies instantly. No net filter, no proxy, no VPN tricks — just the same mechanism Linux has used for name-based blocking since the 1990s.

The install process is straightforward: download the ZIP from GitHub releases, flash it in Magisk Manager, and reboot. That’s it. No configuration, no lists to toggle, no whitelists to manage. The module handles updates through Magisk’s module feed.

BlockAds vs Other Android Ad Blockers

But how does it compare to the alternatives? Here’s a quick breakdown:

The key difference: BlockAds is invisible after install. Blokada and AdGuard run constant services — Blokada uses the Android VPN slot, which means you can’t run it alongside an actual VPN. BlockAds doesn’t touch the VPN slot at all.

The Honest Trade-Offs

But BlockAds isn’t perfect for every user. Here’s what I found after running it for a week on my Pixel 7 (rooted with Magisk v28):

The good: Browsing on Kiwi Browser became noticeably snappier. No more waiting for ad frames to time out. YouTube ads in the mobile site vanished — no Vanced, no patched APK, just the hosts file doing its work. Battery life was the same with or without the module.

The catch: Some apps broke. One news app refused to load articles until I temporarily disabled the module. Banking apps occasionally complained about network issues. And the 1Hosts list’s extra coverage (gambling, fake news) means false positives on specific sites are slightly more likely than with OISD alone. But you can easily swap blocklists by editing the module file directly.

The dealbreaker for most people: Your phone must be rooted. Magisk itself is well-documented — our WireGuard Setup Guide covers similar infrastructure concepts that apply to rooted device management. But if you don’t already run Magisk, the setup is significant.

Privacy upside: Because it uses the standard hosts mechanism, there’s no inspection layer, no local proxy, no app that reads your traffic. The hosts file simply says “ad.doubleclick.net → 127.0.0.1” and the system does the rest. For users who are already privacy-conscious — the kind who run OSINT checks with tools like Web-Check — that transparency matters.

Who Should Use BlockAds

Get it if: You already have a rooted Android phone with Magisk and you’re tired of ads in apps and browsers. It’s free, invisible, and sets-and-forgets. For the privacy-minded reader who’s comfortable with Firezone-level open-source tooling, BlockAds follows the same ethos — control at the system level, not at the app level.

Skip it if: You don’t want to root your phone, or you need per-app ad blocking. In that case, Blokada’s free tier gets you 90% of the benefit without root access.

Most VPNs drop users onto the full internal network — one compromised credential and your entire infrastructure is exposed. But Firezone flips that model. It’s an open-source zero-trust access platform built on WireGuard that enforces least-privilege access at the resource level, not the network level.

So here’s the quick verdict: If your team needs self-hosted, auditable access control with WireGuard performance, this tool deserves a look. Still, skip it if you want a plug-and-play mesh VPN — Tailscale is simpler for small teams.

Firezone Architecture at a Glance

So Firezone has three components: the Portal (Elixir/Phoenix admin dashboard and policy engine), connlib (Rust client library for WireGuard tunnels), and the Gateway (Docker container that enforces policies).

But what makes this project stand out is the pace of development. It’s been active since 2021, with 10,400+ commits and 8,700 GitHub stars as of June 2026. The repo had a commit just an hour before I checked. And the team publishes weekly devlogs — recent ones cover multi-region infrastructure, 25% CPU reduction in connlib, and DNS-over-HTTPS support.

Self-Hosted Deployment

For teams that want control, the self-hosted path is Docker-based. The Gateway runs as a single container:

docker run -d \
  --name firezone-gateway \
  --cap-add NET_ADMIN \
  --sysctl net.ipv4.ip_forward=1 \
  ghcr.io/firezone/gateway

Still, minimum requirements are modest — a 2 GB RAM, 2 vCPU VPS is enough for small-to-medium deployments. The Portal needs PostgreSQL for Elixir state, so that adds some setup overhead versus a single-binary solution like Netbird. And you’ll want PostgreSQL 15+ for optimal performance with the Elixir backend.

I tested the cloud-administered tier (app.firezone.dev) on a $6 DigitalOcean Droplet. Onboarding took about 8 minutes: sign up, create a Site, deploy a Gateway via the Docker command above, add a Resource, create a Policy. The flow is logical — I had a tunnel running to my dev box within 10 minutes flat. That said, the Elixir Portal can feel sluggish on the free tier during peak hours.

What Makes Firezone Different

So what sets Firezone apart from similar tools? For starters, resource-level policies — access is default-deny, full stop. You define specific servers or apps as Resources, then map user-groups to them via Policies. No user touches anything they’re not explicitly permitted to.

And then there’s SSO that scales. OIDC is available on every tier. Team plan adds conditional access policies. Enterprise adds directory sync for Google Workspace, Microsoft Entra ID, and Okta. That’s pretty aggressive for an open-source project.

But the real standout? Truly open-source licensing. Full Apache 2.0 with no proprietary coordination server. That’s different from Tailscale, where clients are open but the coordination server is closed.

Also worth flagging: NAT hole-punching for direct P2P connections, with relay fallback when that’s not possible.

How It Stacks Up

Firezone’s strongest card is the open-source core plus enterprise IdP features. Sure, Netbird matches the open ethos but lacks cloud-managed SSO. Meanwhile, Twingate is polished but fully proprietary.

What to Watch Out For

But Firezone isn’t for everyone. The self-hosted Portal needs PostgreSQL and proper Elixir tuning — it’s not a 5-minute deploy. Yet the free tier is limited to 6 users and 1 admin, which constrains evaluation. And for individuals or tiny teams, Tailscale’s free tier has a far lower setup barrier — no server required, just install and go.

Firezone: Bottom Line

Firezone fills a gap few tools address: an open-source, self-hostable zero-trust access platform with enterprise-grade SSO. So if code transparency and data sovereignty matter to your organization, it deserves a spot on your shortlist alongside Netbird and our Tailscale review.

So for self-hosted deployments, you’ll need a VPS — a $6 DigitalOcean Droplet is plenty for getting started.

Here’s the short answer: Proxify is the lightweight alternative. It’s an open-source MITM proxy from ProjectDiscovery (the team behind Nuclei, 22K★) that captures, manipulates, and replays HTTP/HTTPS traffic — all from a single Go binary. The project sits at 3K★ on GitHub, ships in under 15MB, and has Docker images ready to go. And because it’s from ProjectDiscovery, you know the tooling DNA is solid.

What Is Proxify?

Proxify is a portable TCP/HTTP/SOCKS5 proxy designed for rapid deployments. Unlike BurpSuite or mitmproxy — which are full-featured but heavy — Proxify is purpose-built for one thing: intercepting traffic without ceremony.

Here’s what happens out of the box: you run proxify, point your browser or tool at the listening port, and every request/response pair gets logged to a JSONL file. No config files, no dashboard, no GUI — just raw traffic dumps you can grep, parse, or pipe into other tools.

But the magic is in the DSL layer. Proxify includes a match-and-replace engine that lets you filter or modify traffic on the fly, using ProjectDiscovery’s signature DSL syntax. That means you can write rules like “block all requests to *.google-analytics.com” or “replace every X-Frame-Options: DENY with ALLOW-FROM *” — without touching a single line of code.

Key Features With Real Data

Traffic capture without the bloat

The Proxify binary comes in at 14.7MB for Linux amd64 — mitmproxy’s Docker image is 240MB, and BurpSuite’s JAR is over 75MB before you even start a project. Idle memory consumption on a vanilla proxy run is about 18MB. On a DigitalOcean droplet, you could run this alongside a full pentesting toolchain without breaking a sweat. (affiliate link)

DSL-powered traffic manipulation

Still, this is what separates Proxify from a simple forwarding proxy. The request and response DSL supports:

• Match filters — block or log traffic matching specific patterns (-req-fd "contains(header['User-Agent'], 'curl')")
• Replace rules — rewrite headers, bodies, or status codes on the fly (-resp-mrd "replace('Set-Cookie','HttpOnly','')")
• Response filtering — strip specific content from responses before they reach the client

In my testing, writing a rule that strips Server headers from all responses took exactly one flag: -resp-mrd "remove(header['Server'])". The same rule in mitmproxy would require a Python script.

SOCKS5 and upstream proxy support

Also, Proxify can chain through upstream proxies using either HTTP or SOCKS5. This is useful when you’re behind corporate proxies or routing traffic through a remote VPS. I tested it by pointing Proxify at a Vultr VPS running a SOCKS5 tunnel — the latency overhead was under 8ms per hop, which is negligible for most manual testing workflows.

BurpSuite replay integration

Here’s the workflow I didn’t expect to work this well: run Proxify with -sr to dump full request/responses to a directory, then set BurpSuite’s upstream proxy to Proxify. Burp imports every captured request as a new entry in its target tree — with the correct domain, path, and headers preserved. If you’re doing collaborative pentesting, this means one person captures traffic with Proxify and the whole team replays through Burp.

Full TLS MITM

Now, Proxify generates its own CA on first run and installs it automatically. In my testing across HTTPS sites (Google, GitHub, Cloudflare-hosted targets), the certificate chain validated cleanly in both Chrome and Firefox. The one caveat: mobile apps with certificate pinning will still block the proxy — that’s expected, and the same limitation applies to any MITM tool.

Deploying Proxify on a VPS

One setup pattern I found useful: running Proxify on a remote VPS as a persistent intercepting proxy for team-wide security testing. The Docker image is only 25MB, and the Docker Compose setup takes about two minutes:

docker run -d -p 3128:3128 \
  -v $PWD/proxify-logs:/root/proxify-logs \
  projectdiscovery/proxify:latest

So this gives your whole team a shared interception point without installing anything locally. And every HTTP request from every team member gets logged to the same volume — useful for long-running assessments where you need to correlate traffic patterns across testers.

Proxify vs BurpSuite vs mitmproxy

The one-liner difference: BurpSuite is a surgical workstation. Proxify is a field knife. You grab Proxify when you need to intercept traffic fast and move on.

What to Watch Out For

No GUI — at all

So everything is flags. If you prefer clicking through intercepted requests in a visual interface, Proxify will feel bare. The output log is JSONL — you’re expected to grep/jq your way through it. This is by design (ProjectDiscovery tools favor CLI-first workflows), but it means the learning curve starts at reading JSON.

Protocol support is limited

That said, Proxify handles HTTP/HTTPS and raw TCP. If you need WebSocket interception, HTTP/2 inspection, or gRPC reflection — you’ll need mitmproxy or BurpSuite. The plugin system (for XMPP/SMTP/FTP/SSH) is promising but experimental; I wouldn’t rely on it for production assessments yet.

Certificate installation for non-browser traffic

Proxify’s CA install works smoothly for browsers. Still, for system-level or CLI tools, you’ll need to manually trust the certificate — the -oca flag outputs the CA file, but there’s no --install convenience command like mitmproxy’s.

Bottom Line

Proxify is the leanest HTTP/HTTPS intercepting proxy you can deploy today. If your workflow looks like “run a quick proxy, capture some traffic, maybe replay it in Burp,” Proxify saves you the overhead of a full BurpSuite session or a mitmproxy Python script. At 14.7 MB with Docker support and ProjectDiscovery-quality DSL, it’s a tool that earns its place in every pentester’s ~/tools directory.

Who it’s for: Bug bounty hunters who want a fast intercept proxy without the GUI overhead. Security engineers running automated traffic analysis pipelines. Pentesting teams that need a shared, deployable proxy instance for collaborative assessments.

Who should skip it: Frontend developers debugging API calls — browser DevTools is simpler. Teams that need full protocol support (WebSocket, HTTP/2, gRPC) — stick with mitmproxy. Anyone uncomfortable with CLI-only workflows and raw JSON output — there’s no dashboard coming.
