Open Use License is a source-available license text designed for software projects, with a core positioning of "Free to use, Open to read, Honest attribution." It is based on the Elastic License 2.0 and strengthens attribution preservation and multi-tenant restrictions through additional clauses. The page provides a copyable LICENSE template, requiring users to fill in the year and author before committing it to their projects.
In terms of functionality, it is not a development framework or API, but rather a legal text used to regulate software usage, distribution, deployment, and derivative works. The most prominent clause is Attribution Preservation: you must not remove, modify, obscure, replace, or supplement attribution elements in the software, including logos, icons, product names, copyright notices, about pages, or version information. Another key restriction is Multi-Tenant Use: you must not host, deploy, manage, or facilitate multiple instances of the software or derivative works as a service. This clearly distinguishes it from permissive open-source licenses like MIT and Apache.
The page explicitly states "Free to use," and the license text can be copied and used directly. However, it also declares that the text is provided as-is, does not constitute legal advice, and users should consult a qualified attorney before use. In terms of ecosystem, it references the Elastic License 2.0 but exists independently, explicitly stating it is not affiliated with, sponsored by, or endorsed by Elastic N.V. The page also recommends using it in conjunction with a contributor license agreement.
The pros are its short text and clear intent, making it suitable for commercial software teams who want to make their source code readable and allow free use, while preventing third parties from removing branding or repackaging it as a multi-tenant hosted service. The cons are that it is not a traditional open-source license; its strong restrictions may reduce community contributions, inclusion in Linux distributions, or acceptance in enterprise compliance. The documentation is also relatively brief, lacking FAQs, compatibility notes, and real-world use cases.
It is suitable for source-available commercial software, independent developer tools, and product owners looking to restrict cloud provider hosting competition; it is not suitable for projects pursuing OSI open-source certification, maximizing distribution, or relying on open-source foundation ecosystems. Access from China is not mentioned in the main text and is therefore deemed unknown. There is no billing information regarding payments. Alternative options include Elastic License 2.0, Business Source License, AGPLv3, Apache License 2.0, and MIT License.
