How MagicLock compares
Honest, factual comparisons with the tools Python teams already know — what each does well, and where MagicLock differs.
Python teams protect shipped code in four broadly different ways: obfuscation (PyArmor), encryption loaders (SOURCEdefender), compilation (Nuitka, Cython), and packaging (PyInstaller). Each is a respected tool that solves a real problem well. This page compares them factually — what each approach does, what it deliberately does not do, and where MagicLock fits.
The short version: compilers and packagers solve performance and distribution, not licensing. Obfuscation raises the cost of reading your code but still hands the complete program to whoever holds the file. MagicLock's approach is different in kind, not just degree: encryption plus device-bound licensing — an artifact that is not merely hard to read but refuses to become a program at all on machines you haven't authorized.

How to choose
You want your code hard to read, with a mature, widely-used tool
PyArmorYou want speed or C-level integration
Nuitka / CythonYou want one double-clickable file
PyInstallerYou want shipped code and models that only run on machines you authorize — verified fully offline, with licensing, expiry, and an optional remote kill switch built in
MagicLockThese tools also compose: many teams protect with MagicLock and still package with PyInstaller, or use MagicLock's compiled tier, which builds on native compilation itself.
