The short version

  • Only OPNsense has a free tier, so it costs nothing to try first.
  • Each has a real cost: Domotz the Managed Device Plan bills in bundles of ten, so a network with, for example, eleven devices to manage pays for twenty rather than a precise count; OPNsense throughput depends entirely on hardware you selected yourself, and intrusion prevention at multi-gigabit rates will saturate a machine that handled plain firewalling fine, with no vendor sizing commitment to fall back on.
  • They diverge on capability: Domotz covers Device discovery and monitoring, OPNsense covers Stateful firewall on pf.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

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

Domotz

  • An MSP with high device density per client site wanting predictable flat pricing per collector rather than counting individual devicesnot OPNsense
  • An IT integrator managing many small sites with few devices each, better served by per-device pricing than a flat collector feenot OPNsense
  • A field services or retail IT team needing remote access to branch equipment without configuring VPN tunnels to each sitenot OPNsense
  • A team wanting a directly comparable public price against Auvik before starting a sales conversation with either vendornot OPNsense

OPNsense

  • Replacing a small business firewall appliance whose renewal quote exceeded the cost of the hardwarenot Domotz
  • Branch offices where the firewall configuration must be produced by Ansible rather than by handnot Domotz
  • Sites that need WireGuard and intrusion prevention on the same box without separate feature licencesnot Domotz
  • A homelab or lab network needing VLAN routing, multi-WAN and DNS filtering on one machinenot Domotz

Where each one falls short

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

Domotz

  • The Managed Device Plan bills in bundles of ten, so a network with, for example, eleven devices to manage pays for twenty rather than a precise count
  • The Collector Plan gives full access per collector regardless of device count monitored by that collector, which can be inefficient for a site with very few devices relative to the flat $35 fee
  • As a SaaS platform, ongoing monitoring depends on the local Collector maintaining connectivity to Domotz's cloud, so a site-level outage that also cuts collector connectivity limits remote visibility exactly when it is needed
  • Feature depth for large enterprise NOC-style operations is narrower than platforms built for that scale, since Domotz's roadmap centres on MSP and integrator use cases
  • Remote access without VPN configuration is convenient but depends on Domotz's own relay infrastructure remaining available and trusted, which is a different security posture than a customer-controlled VPN
  • Volume and annual discounts exist but the specific discount schedule is not fully published, so very large deployments still benefit from negotiating directly rather than relying on the list price

OPNsense

  • Throughput depends entirely on hardware you selected yourself, and intrusion prevention at multi-gigabit rates will saturate a machine that handled plain firewalling fine, with no vendor sizing commitment to fall back on.
  • The weekly update cadence is good for security but means more change events than a team used to annual appliance firmware, and occasional regressions reach production installations.
  • FreeBSD underneath limits driver support compared with Linux, so recent network cards and some virtualisation drivers can be unsupported or slow.
  • The plugin ecosystem is uneven in quality; some plugins are maintained by a single contributor and can lag a major release, breaking a function you depended on.
  • Community support is a forum, so an outage at two in the morning on the free edition is your problem alone unless you bought the business subscription in advance.

Answered from the vendors’ own pages

Domotz: Is pricing based on networks, sites or devices?

Devices. Domotz states explicitly there are no per-site, per-network or per-user charges.

OPNsense: How is it different from pfSense?

It is a 2015 fork with an MIT licence, a fixed weekly release cadence, a complete configuration API and a different interface. Feature coverage is comparable; the release process and API are the real differences.

Domotz: What is the difference between the two plans?

The Collector Plan is a flat $35/month per collector with full access to everything that collector monitors; the Managed Device Plan is $1.50/month per device, billed in bundles of ten.

OPNsense: Do I need the Business Edition?

Only if you want commercial support or a slower, stabilised update stream. No features are withheld from the community edition.

Domotz: Is there a free trial?

Yes, a 14-day free trial is offered.

OPNsense: Can it handle a gigabit internet connection?

Plain firewalling on modest current hardware, comfortably. With Suricata inspection enabled, expect to need a considerably stronger CPU.
