Lupa embeds the Lua and LuaJIT runtimes into CPython via Cython, allowing Python code to execute and interoperate with Lua code. It supports multiple isolated Lua runtimes, coroutine bridging, and releases the GIL when calling into Lua.

Use cases

• embed lua scripts in a python application
• run fast luajit code from python for hot paths
• execute dynamic user-provided lua scripts
• bridge python and lua coroutines
• sandbox a lightweight scripting language inside python

When to choose

• you need a small, fast embedded scripting runtime in Python
• you want LuaJIT speed for computational code without writing C extensions
• you need bidirectional Python-Lua object iteration and coroutine support

When to avoid

• you only need to call Python from Lua rather than the reverse
• you need full Lua ecosystem batteries that Python already provides
• you want a pure-Python solution without compiled extensions
