===================
Open Source License
===================

Emscripten is made available under two permissive open source licenses: the *MIT license* and the *University of Illinois/NCSA Open Source License*.

There is little, if any, practical difference between the licenses. They are both offered because the:

- *MIT license* is well known and understood.
- *University of Illinois/NCSA Open Source License* allows Emscripten's code to be integrated upstream into LLVM, should the opportunity arise.

The license for Emscripten |release| is reproduced below. The `current full license <https://github.com/emscripten-core/emscripten/blob/main/LICENSE>`_ can be found on GitHub (and is also present in the root of the SDK).
