LicenseMITlicense, commonly known as the MIT License, is a permissive free software license originated at the Massachusetts Institute of Technology (MIT). It is one of the most widely used open source licenses due to its simplicity and broad permissions.

The license grants permission to use, copy, modify, merge, publish, distribute, sublicense, and sell copies of the software. The main obligation is to include the copyright notice and the license text in all copies or substantial portions of the software. It provides a warranty disclaimer stating the software is provided as is without warranty of any kind, and that the authors are not liable. Because it is permissive, it does not require derivative works to be released under the same license, allowing inclusion in proprietary software.

The MIT License is compatible with many other licenses and is commonly used for libraries, frameworks, and applications across various ecosystems. Its brevity and permissiveness contribute to widespread adoption, but users should review the exact terms to ensure compliance.

The MIT License is closely related to the X11 license and shares a similar structure and wording. It has remained stable since its creation at MIT.
