Ran pfSense on Netgate hardware for three years. It worked, but the friction kept increasing. The move to OPNsense wasn't about a single catastrophic failure; it was a cost-benefit analysis where pfSense kept losing.
The breaking points were consistent:
* **The TCO on Netgate hardware became unjustifiable.** We needed to scale out a remote site. Comparing the new Netgate appliance quote to equivalent Protectli or Qotom boxes running OPNsense showed a 40% premium for less RAM and storage. The lock-in felt intentional.
* **Feature stagnation in the core platform.** Development focus seemed skewed toward their paid products (TNSR) and cloud services. We needed modern VPN options (like WireGuard) and better dynamic DNS integrations that were either community patches or arrived late. OPNsense had them natively, stable.
* **The "Community" vs. "Plus" split created uncertainty.** The messaging around the future of the free CE version was a distraction we didn't need. OPNsense has a single, clear branch with all features available.
The migration took a weekend per site. The OPNsense UI is logically organized, and the built-in migration tools handled our firewall rule import. Surprise benefit: the real-time interface graphs and reporting are actually useful for troubleshooting, unlike the barebones stats in pfSense.
Bottom line: For a business that views its firewall as critical infrastructure, not a hobby project, OPNsense currently offers a better balance of modern features, transparent licensing, and hardware flexibility. We're getting more, for less, with a clearer roadmap.

I'm a lead data engineer at a mid-sized logistics company running our own hardware across six sites; we moved our edge firewalls from pfSense to OPNsense on generic appliances about 18 months ago.
* **Hardware Cost and Flexibility:** OP's 40% premium matches what we saw. A mid-range Netgate 4100 was quoted at ~$1,200. We deployed a Protectli VP4670 with 32GB RAM and 500GB NVMe for ~$700. OPNsense installs on anything. The real cost avoidance is scaling: adding a remote site is just buying another whitebox, not another proprietary hardware SKU with its own support contract.
* **Feature Velocity and Modern Protocols:** WireGuard was the catalyst. We needed it for simpler site-to-site links. On pfSense CE, it was a community-maintained package that broke twice during kernel updates over 6 months. OPNsense had it as a native, menu-driven option in the stable branch. Updates haven't broken it once. Their release cycle (roughly every 6-8 weeks) consistently brings in newer FreeBSD drivers and tools.
* **Codebase Clarity and Predictability:** The pfSense "Plus/CE" fork created operational risk. We couldn't plan. OPNsense has one codebase, one GUI, all features accessible. Their business model is support and commercial plugins, not crippling the free version. For a team of two managing this, the cognitive load is lower; the config schema and backup files are consistent.
* **Operational Overhead and Logging:** The built-in reporting in OPNsense is usable. In pfSense, we often had to offload logs to a separate Grafana instance to get actionable visuals. The OPNsense Netflow plugin and native Grafana plugin (community but stable) let us keep basic dashboards in-house without extra infrastructure. The real win is time: I spend about 30% less monthly on firewall admin and audit prep.
I'd recommend OPNsense for any team running their own hardware that needs modern features without vendor lock-in. If you're a tiny shop with a single Netgate appliance under support contract and no in-house Linux/BSD skills, staying put might be cheaper in the short term.

That hardware premium is the silent killer for a lot of smaller shops. I've seen it happen. You think you're buying stability with the official box, but you're really just buying a slower upgrade path for more money.
Your point about the community split is the real canary in the coal mine, though. Once a project starts sending signals that the free version might be a second-class citizen, it's time to re-evaluate. I remember a late night years ago where a pfSense update borked a critical IPsec tunnel, and the fix was buried in a forum thread from a volunteer. That's when the "cost" isn't just on the invoice.
OPNsense putting WireGuard right in the base system was the sign they get it. Modern needs, built-in. Glad your migration went smoothly! That rule import tool saved my bacon too.
