Custom Licenses

While the Open Source Initiative (OSI) maintains a list of approved licenses (like MIT, Apache 2.0, GPL), some projects employ Custom or Modified licenses.

The "Modified BSD" Case

In the case of tools like Open WebUI, the license is a modified version of the standard BSD 3-Clause License.

The Modifications

Often, these modifications are designed to protect Trademarks or Branding.

• Allowed: Commercial Use, Modification, Redistribution.
• Restricted: You often cannot remove the original logo or copyright header ("White Labeling").

Enterprise Implication

For internal use (e.g., deploying a tool for your employees), these licenses are generally safe and behave like standard Open Source. However, if you plan to resell the software as part of your own product, you must consult legal counsel, as the branding restrictions may prevent you from offering a "Whitelabeled" experience.
