Comparison
LibreQoS and Preseem
These are the two closest approaches among QoE platforms: both reject deep packet inspection, and both use active queue management and fair queueing rather than application classification. Preseem shapes at the subscriber plan and access point levels. LibreQoS nests every circuit inside a shaping hierarchy that also covers sites, OLTs, and backhaul links. Preseem capabilities below are stated in their own published datasheets and materials.
Closest, Not Identical
Both control queues. The question is where, and how finely.
Preseem AQM datasheet describes FQ-CoDel with bulk and interactive flow separation, plan-rate enforcement, and a deliberately anti-DPI stance — a philosophy LibreQoS shares. Its Automatic AP Capacity Management datasheet adds automatic bandwidth control on busy access points, included in all tiers. Preseem deserves credit here: FQ-CoDel is published AQM from the same research family, which is exactly why this comparison stays technical.
Preseem enforces at the levels its docs describe: QoE-optimized plan enforcement per subscriber and AQM capacity management per access point — the TwoLevelMQ policy — with manual site bandwidth caps available. Those levels matter, and Preseem shapes them with published AQM. LibreQoS adds the dimension above them: every subscriber circuit runs CAKE per-flow queueing inside an HTB envelope, and every circuit nests under explicit queue classes for its AP, site, OLT, and backhaul. When a backhaul link congests, the hierarchy shapes that contention at the link instead of letting it degrade every subscriber upstream.
Beyond enforcement, the platforms optimize for different jobs. Preseem is a network intelligence platform: one view across vendors, support triage, churn risk by site, revenue reporting, and BEAD/EA-CAM compliance data. LibreQoS stays closer to the network: RTT, retransmit, QoO, and flow evidence per circuit, with Insight for multi-node history and ASN analysis. Business reporting is left to the billing stack.

Ask Both Vendors
Questions worth asking in any Preseem evaluation
- 01When an access point is congested, how finely is the relief applied — at the AP, per plan rate, or per subscriber flow?
- 02When the backhaul itself congests, is it shaped as part of the enforcement hierarchy, or only monitored?
- 03Which metrics come from our own gear via integrations, and which are measured by the platform itself?
- 04How is latency under load measured — idle probes, or actual subscriber traffic during peak?
- 05What does the enforcement story look like on fiber, where integrations rather than appliances provide the data?
- 06Can we run a before/after quality test on our own network during evaluation?
Verify It Yourself
Don't decide on vendor claims
Run the public Internet Quality Test on a busy-hour circuit, deploy LibreQoS on spare hardware or a pilot site, and run it again. Idle and loaded latency, loss, throughput, and a QoO grade — measured on your own network.
