Features & Specs

Lightweight and embeddable

MuJS is designed to be a lightweight, embeddable JavaScript interpreter with a small footprint, making it ideal for embedding in resource-constrained applications such as PDF viewers (it is used in MuPDF), IoT devices, and other software where a full JavaScript engine would be overkill.
Simple C API

MuJS provides a clean, straightforward C API for integrating JavaScript scripting into C/C++ applications. The stack-based API is easy to understand and use, making it relatively painless to bind native functions and objects to JavaScript.
No external dependencies

MuJS has no external dependencies beyond the standard C library, which makes it extremely easy to compile and integrate into projects across different platforms without worrying about dependency management.
ISO C compliant and portable

The codebase is written in portable ISO C (C99), which means it can be compiled on virtually any platform with a standard C compiler. This makes it highly portable across operating systems and architectures.
Liberal open-source license

MuJS is released under the ISC license, which is a permissive open-source license similar to MIT/BSD. This makes it suitable for use in both open-source and proprietary/commercial software without restrictive licensing concerns.
