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.

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.
