Commercial licensing
holger-ui's source code is licensed under AGPL-3.0-only (see LICENSE). The AGPL is a strong network-copyleft license: if you run a modified version of holger-ui and let users interact with it over a network, the AGPL requires you to offer those users the corresponding source of your modified version.
That obligation does not fit every organization. The original holger-ui code is owned jointly, in equal shares (50/50), by Vetra Automation AB and Ignalina ApS. As co-owners, Vetra Automation AB and Ignalina ApS can jointly offer the same code under separate commercial terms — for example, to organizations that want to embed or modify holger-ui without the AGPL's source-availability obligations.
What this document is — and is not
- This is informational. It describes that a commercial option exists and how to start a conversation about it.
- It is not a license grant, an offer, or a contract. No commercial license exists until both co-owners — Vetra Automation AB and Ignalina ApS — and the licensee sign a written agreement.
- Simply contacting the co-owners, downloading holger-ui, or using it does not grant you a commercial license or waive any AGPL obligation. Until a commercial agreement is executed, your use is governed solely by AGPL-3.0-only.
- Nothing here is legal advice. Obtain your own legal review of how the AGPL applies to your deployment.
Who might want a commercial license
You may want to get in touch if you intend to:
- distribute a modified holger-ui, or offer it as a hosted/SaaS service, without meeting the AGPL §13 network source-availability requirement;
- embed holger-ui (or substantial parts of it) into a proprietary product;
- obtain a warranty, indemnity, support, or SLA that the open-source license explicitly disclaims.
If you deploy an unmodified holger-ui internally and are comfortable with the AGPL, you generally do not need a commercial license — the open-source license already covers that use.
How to get in touch
Write to gunnar@gunnar.rs. Please include:
- your organization and intended use (internal, hosted/SaaS, embedded/OEM);
- whether you intend to modify holger-ui;
- the scope you are interested in (support, warranty, relicensing, or a combination).
Terms, pricing, and availability of any commercial license are determined jointly by Vetra Automation AB and Ignalina ApS and are set out in the written agreement, not in this file.
