Firezone Review 2026: Open-Source Zero-Trust VPN on WireGuard

The traditional VPN is dying. Not hyperbole — enterprise security teams are actively replacing perimeter-based access with zero-trust architectures. And Firezone is one of the most compelling open-source options in this space right now. After spending a week testing it on a $6 DigitalOcean VPS, here’s what stood out — and what didn’t.

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.
