Other AST, loader, and online tools

Smaller or more specialised tools that come up when evaluating Python source protection, and how each relates to pyobfus.

CodeEnigma compiles, compresses, encrypts, and wraps Python bytecode behind an AES-GCM/Cython loader. It shares pyobfus's transparent-alternative positioning, but serves a different workflow: pyobfus is AST source-to-source, emits ordinary .py files, and retains a reverse mapping for production tracebacks instead of requiring a custom encrypted loader.

python-obfuscator by davidteather is a small MIT-licensed AST tool with independent toggles for renaming, hexadecimal strings, dead code, and an exec wrapper. It is useful for experiments and simple scripts; pyobfus adds scope-aware multi-file rewriting, framework presets, configuration, stable JSON interfaces, reverse mapping, and MCP integration.

SOURCEdefender encrypts selected modules into .pye files loaded through an import hook. It can be composed after pyobfus when encryption at rest is the priority; it is not a source-to-source replacement for pyobfus's project-wide mapping and debugging workflow.

Browser-based Python obfuscators have their own section above.
