This eliminates a massive bottleneck for the Python-in-the-browser ecosystem, and Simon immediately proved its value by using AI tools to package and ship a C++ based WebAssembly experiment.</p> <h2 id="posts">Posts<a class="anchor" href="#posts">#</a></h2> <p><strong><a href="https://simonwillison.net/2026/Jun/13/publishing-wasm-wheels/#atom-everything">Publishing WASM wheels to PyPI for use with Pyodide</a></strong> With Pyodide 314.0, developers can now publish Python packages built for Pyodide directly to PyPI, removing a major hurdle where maintainers previously had to manually review and host over 300 packages themselves. To celebrate, Simon used Codex and GPT-5.5 xhigh to package his experimental C++ Luau WebAssembly project, successfully building and deploying it via GitHub Actions. True to form, he then used ChatGPT to draft a BigQuery SQL query to explore PyPI&rsquo;s dataset, discovering that 28 packages are already utilizing the new <code>pyemscripten_202*_wasm32</code> tags.</p>
