The short version

  • Each has a real cost: FreeBSD much smaller hardware and driver support than Linux, especially on laptops and new devices; OpenVPN open source OpenVPN, while free, requires real technical skill to configure, secure and maintain without the Access Server admin layer
  • They diverge on capability: FreeBSD covers Unified base system, OpenVPN covers Open source core.
  • Prices and features above were last checked on 1 September 2026.

Only in OpenVPN

  • Open source core
  • Access Server admin UI
  • Per-connection licensing
  • Free tier
  • Cross-platform clients

What people use each for

The jobs each tool is most often brought in to do.

FreeBSD

  • Storage servers where ZFS integration and data integrity are the prioritynot OpenVPN
  • Network appliances and firewallsnot OpenVPN
  • Products that need a permissive licence for embedded or commercial redistributionnot OpenVPN

OpenVPN

  • A technical team wanting a fully free, self-configured VPN server using the open source protocol without any vendor relationshipnot FreeBSD
  • A small business wanting a supported, easier-to-administer VPN server, willing to pay per concurrent connection rather than per employeenot FreeBSD
  • An organisation with more staff than typical concurrent VPN usage, since Access Server bills only active simultaneous connections, not total accountsnot FreeBSD
  • An IoT or large-scale deployment needing custom Enterprise pricing above 2,000 connectionsnot FreeBSD

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

FreeBSD

  • Much smaller hardware and driver support than Linux, especially on laptops and new devices
  • Most commercial software and container tooling targets Linux first, and FreeBSD support is often absent
  • Smaller community and hiring pool, so operational knowledge is harder to source
  • Desktop use is possible but is not where the project’s attention goes

OpenVPN

  • Open source OpenVPN, while free, requires real technical skill to configure, secure and maintain without the Access Server admin layer
  • Per-connection billing on Access Server means usage spikes, such as an all-hands remote day, can push simultaneous connections over a licensed limit and block new connections until usage drops or the plan is upgraded
  • OpenVPN's traditional hub-and-spoke architecture routes traffic through a central server, unlike mesh VPN tools like Tailscale or NetBird that establish direct peer-to-peer connections where possible, which can add latency
  • Client configuration and certificate management for the open source version is more manual and error-prone than newer VPN tools with zero-config onboarding
  • Access Server pricing above the Growth tier reverts to custom Enterprise quoting, so very large deployments lose the pricing transparency of the lower tiers
  • The protocol's throughput is generally lower than newer kernel-integrated protocols like WireGuard under equivalent conditions, which matters for high-bandwidth use cases

Answered from the vendors’ own pages

FreeBSD: Is FreeBSD free?

Yes, free and open source under the permissive BSD licence.

OpenVPN: Is OpenVPN free?

The open source protocol and software are free under the GPL; Access Server, the commercial packaged product, charges per simultaneous connection beyond a free 2-connection tier.

FreeBSD: FreeBSD or Linux?

Linux has far broader hardware support and is what most software targets. FreeBSD offers a unified base system, mature ZFS and jails, and a permissive licence, which matter most for storage, networking and embedded products.

OpenVPN: What counts as a connection for billing purposes?

A simultaneously active connected device, not a registered user account or total device count; unlimited accounts and devices can be created but only the licensed number can be connected at once.

FreeBSD: What are jails?

OS-level virtualisation that predates modern containers, isolating processes and filesystems with less overhead than a virtual machine.

OpenVPN: How does OpenVPN compare with WireGuard-based tools like Tailscale?

OpenVPN uses a traditional hub-and-spoke VPN architecture rather than the mesh, peer-to-peer approach used by newer tools like Tailscale or NetBird.
