UniFi OS Server is the downloadable software with which customers run UniFi applications on their own server hardware, instead of on a Ubiquiti console or Ubiquiti-hosted service. The downloads page lists UniFi OS Server for download, and states that release software components are licensed under the GNU General Public License as well as other open-source and free software licenses.[4] The commercial terms that apply to the server are in Schedule 3 to the Terms of Service, last modified 2025-05-23.[1] Because the schedule is an exhibit to the Terms of Service, and the Terms of Service provide that a conflict between the Terms and a schedule is resolved by giving precedence in the order specified in those documents or, if none is specified, to the schedule first, the schedule is the controlling text for this software.[2]
Assent
By downloading, installing, accessing or using UniFi OS Server (the “Service”), the user agrees to Schedule 3.[1] The schedule uses “Service” for the software, which differs from the EULA’s use of “Software” for firmware embedded on a Product.[3] A server deployment may therefore be subject to the Terms of Service and Schedule 3 rather than the EULA alone.
Cloud features and registration
The schedule distinguishes the core server from “Cloud Features”: remote management, software updates (including security patches), cloud backup and SD-WAN. These require registration of an Account and enabling the remote access feature. A user who does not sign in with an Account, or who disables remote access, assumes all risk and liabilities of running the Service without the Cloud Features.[1]
For licence records, this means a self-hosted server is not independent of Ubiquiti’s account system if security updates and remote management are wanted. Ubiquiti’s own help material describes a separate route for offline operation: local-only management during internet outages or for air-gapped setups.[5]
Limitations on use
The schedule states that the Service may only be used to manage genuine Products and cannot be used to manage non-genuine Products or third-party products.[1] This is the schedule’s closest equivalent to a scope-of-use metric: the number of devices is not counted, but the type of device is restricted. A mixed estate with non-Ubiquiti equipment cannot lawfully be managed through the Service under this language.
The schedule also limits use of Ubiquiti’s marks. The user may not use any Mark as part of the name, trademark or logo of its business, products or services, may not register confusingly similar marks, domain names or designations, may not modify or animate a Mark, may not copy the look and overall impression of Ubiquiti products or websites, and may not place a Mark next to products made by others in a way that suggests association.[1] A managed service provider using UniFi OS Server for customers needs to review these before branding a service.
Covenants, records and audit
Under “Covenants” the user and its Authorized Users agree not to make any statement that constitutes an ad hominem attack on, or otherwise disparages, Ubiquiti, its affiliates, their personnel, services or products, and not to take any action that could adversely affect the goodwill and reputation of Ubiquiti, its affiliates and their products and services.[1] This is a conduct covenant that goes beyond ordinary licence scope, and a practitioner should flag it for legal review because it applies to the Authorized Users as well as the licensee.
The same section requires the user to maintain complete and accurate records related to its obligations. Ubiquiti reserves the right to audit those records to confirm compliance. The user must promptly provide all information reasonably requested by Ubiquiti or its agent, at no cost to Ubiquiti, and cooperate with other reasonable requests. Audits may be conducted during normal business hours following at least 5 days’ written notice.[1] The record keeping duty is general; the schedule does not name specific records or a retention period. A prudent file would show the version of the server software, the Account used to register it, the Products it manages and evidence that they are genuine.
Assignment and third-party access
If the user assigns or transfers the Service to a third party, or permits any third party other than its Authorized Users to access or use it, the user must ensure the third party is informed of the terms and agrees to be bound, and remains liable for the third party’s non-compliance; “You” then includes the third party.[1] This is relevant to hosting providers and integrators who run the server on behalf of an end customer, and to asset transfers on a sale of a business.
Suspension and termination
Ubiquiti may, in its sole discretion, without prior notice and without any reason, suspend, terminate or deny access to all or part of the Service, including disabling features such as remote management, online backup, software updates and SD-WAN. Ubiquiti may use software, hardware or other technology (“Disabling Technology”) for this, and the user may not circumvent or tamper with it.[1] The Terms of Service contain a parallel termination right for Services.[2]
Warranty, liability and indemnity
The Service is provided “as-is” and “as available”, with no warranty, including no warranty that Ubiquiti will continue to develop, provide, update or upgrade any part of the Service.[1] The user must indemnify, defend and hold harmless Ubiquiti, its affiliates and personnel against loss or liability arising from claims about the inaccuracy or breach of the user’s representations, personal injury or property damage caused by the user’s parties, or the user’s use of the Service or Ubiquiti’s suspension or termination of it.[1] The EULA caps Ubiquiti’s liability at one hundred dollars for embedded software.[3]
Automatic updates and open source
The Terms of Service state that Ubiquiti may provide patches and updates, that the user consents to their automatic installation and that Ubiquiti withholds the right to require installation to continue use of the Services.[2] The Terms of Service also state that third-party and open source software is subject to its own licences, which take precedence for that software.[2] The downloads page’s GPL statement applies to release software components.[4] For a component under an open source licence, the licence of that component governs it, as the Terms of Service provide.
Relationship to paid Services
The server software is not itself described as a paid Service. Subscriptions that interact with it (for example UniFi Talk numbers, or the hosting subscription) are separate and fall under the Services General Terms, with their own Fee Schedule and Coverage Period.[6] See paid UniFi subscriptions and license-free software.
Out of scope
This article does not summarise Schedule 1 (Speed Test Server Host) or Schedule 2 (AI Tools, covered in the EULA and Terms of Service article), nor any technical configuration of the server.
