The release was heavily assisted by Claude AI, which found and fixed numerous bugs in the C++ backend, closed test gaps, and added support for many missing Python 3.15 features, bringing the project close to full compatibility for supported modules. AI assistance is also expected to make contributing easier, helping minimize failing programs into bug reports and even attempt fixes. A DOOM engine example compiled with Shed Skin runs over 30 times faster than pure Python. ## Full article daily.dev links to this article rather than hosting it.

Shed Skin 0.9.13 is the first release heavily improved through AI assistance using Claude, which found and fixed many bugs in the C++ backend, closed test gaps, and added support for numerous missing Python 3.15 features. The project is now close to full compatibility with Python 3.15 for its supported modules, though gaps remain such as missing os.walk support due to its use of heterogeneous tuples longer than two elements. _Developers tracking transpiler and Python compatibility updates can follow releases like this on daily.dev._ ### How much faster is Python code after compiling it with Shed Skin? A DOOM engine example compiled with Shed Skin runs more than 30 times faster than the original pure Python version, according to the project's benchmark example. The compiled engine is then imported into a larger program that uses Pygame for the user interface, demonstrating a hybrid approach of transpiling performance-critical code while keeping UI logic in Python. _Anyone weighing Python performance tradeoffs can find transpiler benchmarks like this on daily.dev._ ## Similar posts on daily.dev - [A \(restricted\) Python-to-C\+\+ Compiler: Shed Skin restricted-Python-to-C\+\+ compiler v0.9.11](https://daily.dev/posts/a-restricted-python-to-c-compiler-shed-skin-restricted-python-to-c-compiler-v0-9-11-kjcipyade) · Planet Python · 1 upvotes · 0 comments - [Shed Skin - A \(restricted\) Python-to-C\+\+ Compiler](https://daily.dev/posts/shed-skin---a-restricted-python-to-c-compiler-uvuzqxdgp) · Planet Python · 2 upvotes · 0 comments - [PythoC: A new way to generate C code from Python](https://daily.dev/posts/pythoc-a-new-way-to-generate-c-code-from-python-hhhyci0hl) · InfoWorld · 2 upvotes · 0 comments --- Tags: [#python](https://daily.dev/tags/python), [#ai-coding](https://daily.dev/tags/ai-coding), [#c++](https://daily.dev/tags/c++) [View this post on daily.dev](https://daily.dev/posts/a-restricted-python-to-c-compiler-shed-skin-restricted-python-to-c-compiler-v0-9-13-released-km7w74ydu) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"A (restricted) Python-to-C++ Compiler: Shed Skin restricted-Python-to-C++ compiler v0.9.13 released","url":"https://daily.dev/posts/a-restricted-python-to-c-compiler-shed-skin-restricted-python-to-c-compiler-v0-9-13-released-km7w74ydu","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/a-restricted-python-to-c-compiler-shed-skin-restricted-python-to-c-compiler-v0-9-13-released-km7w74ydu"},"datePublished":"2026-09-02T07:48:34.034Z","dateModified":"2026-09-02T07:48:54.987Z","description":"Shed Skin, a transpiler that converts a restricted subset of Python into optimized C++/machine code, has released version 0.9.13.
