OPNsense vs GL.iNet routers
Both are alternatives to Locked-Down Consumer Routers. Here's how they stack up — verified facts, no spin.
Also searched as GL.iNet routers vs OPNsense — same comparison, one verdict.
OPNsense and GL.iNet routers are closely matched on ownership (90 vs 85) — this one comes down to pricing and to which trade-offs below you can live with.
OPNsense
A powerful open-source firewall/router for a mini-PC.
OPNsense is a BSD-based, open-source firewall and routing platform you install on a small x86 appliance, giving you enterprise-grade networking, VPNs, and filtering on hardware you own.
GL.iNet routers
Consumer-friendly routers that ship with OpenWrt.
GL.iNet sells affordable routers that come with OpenWrt pre-installed under a friendly interface — the easiest on-ramp to open router firmware without flashing anything yourself.

| OPNsense | GL.iNet routers | |
|---|---|---|
| Sovereignty ScoreOur transparent 0–100 composite for data ownership and exit cost. | 90 | 85 |
| Open source | Yes | Yes |
| Self-hostable | Yes | Yes |
| Local-first data | Yes | Yes |
| License | BSD-2-Clause | OpenWrt-based (GPL-2.0) + vendor UI |
| Pricing | Free / open-source | One-time hardware purchase |
| RAM to run it wellThe figure that actually matters, not the vendor's minimum. | 4 GB, or 8 GB if you run intrusion detection | 256 MB models age far better than 128 MB ones |
| Realistic running costWhat the box costs each month if you run it yourself. | Free software on hardware you buy once. A $150–350 mini PC replaces a subscription router permanently. | $50–200 one-off for the hardware |
| Setup timeHonest first-install estimate, not the marketing quickstart. | An afternoon for a working firewall, longer to tune rules | 30 minutes out of the box |
| Ongoing maintenanceThe part nobody budgets for. | Moderate. Firmware updates matter — this is your network edge. | Low, but vendor firmware lags upstream OpenWrt on security fixes. |

Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose OPNsense
if a lower exit cost matters more to you than any single feature, and enterprise-grade features.
Choose GL.iNet routers
if openWrt out of the box — no flashing.
Neither, yet
if both carry a real cost you should weigh first — needs a separate mini-PC/appliance, and vendor UI adds closed pieces on top. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
What it takes to run these yourself
Real requirements and honest running costs, not the vendor quickstart.

OPNsense vs GL.iNet routers — common questions
Is OPNsense a better fit than GL.iNet routers for networking & routers?
It depends on what you are optimising for, and the honest split is this: OPNsense scores 90 to GL.iNet routers's 85 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. GL.iNet routers earns its place on a different axis — openWrt out of the box — no flashing. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
OPNsense keeps its data local or in open formats, so leaving is an export rather than a negotiation. GL.iNet routers is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Is OPNsense free?
OPNsense: Free / open-source. The other side of this comparison, GL.iNet routers, is priced as One-time hardware purchase. "Free" here means no licence fee — if you self-host it you still pay for the server, and the running cost row above is our honest estimate of that.
Can I self-host OPNsense or GL.iNet routers?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are OPNsense and GL.iNet routers both alternatives to Locked-Down Consumer Routers?
Yes — both appear in our Locked-Down Consumer Routers comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Locked-Down Consumer Routers and now choosing between the two replacements, which is a narrower and much easier question.
