COMPARISON
NUT is the free multi-vendor breadth leader. MayaUPS is for teams that want that mixed-fleet direction with a usable bilingual interface, product support, and a deployment model that does not require operators to assemble a monitoring front end themselves.
NUT is free, broad, and valuable for teams that are comfortable with scriptable infrastructure. It remains an open-source reference point for multi-vendor UPS support, especially where operators already know its daemon and configuration model.
MayaUPS combines multi-vendor SNMP monitoring, a bilingual web UI, support, battery forecasting, grouped email alerts, CSV import, role separation, backups, and safety-gated shutdown. It is intended for operators who need the power edge visible through one application rather than through command-line tooling plus separate dashboards.
MayaUPS presents EN-CA and FR-CA pages, readable alarm states, history charts, and operating workflows for monitoring, alerting, and shutdown readiness. Quebec and Canadian procurement reviews may also require French-language support, accessibility evidence, and conformity documentation.
NUT remains highly scriptable, but MayaUPS frames shutdown as a controlled workflow: Observe first, then Dry-run proof, then Armed. Policies can use runtime or event triggers, SNMP-SET UPS shutdown, and an mTLS host agent for ordered host sequences, while live Linux host shutdown remains labelled as bench-verified until final proof is supplied.
NUT is still the right fit when the team wants open-source plumbing and is ready to operate it directly. MayaUPS is the fit when the site wants free multi-vendor monitoring with a supported GUI, local data residency, battery planning, grouped email alerts, and a lighter path to day-to-day operation.
