Briefings
A 2026 article reports on the release of pwasm 0.2a0, a pure Python WebAssembly engine built by the author in January 2026 during AI mania. The engine now handles the full WASM specification and bundles working builds of MicroPython, QuickJS, and Micro QuickJS via PyPI. It is an alpha version, reflecting the author's skepticism despite significant improvements over a 10-month-old model.
Key points
- pwasm 0.2a0 is a pure Python WebAssembly engine released in October 2026, built by the author in January 2026 during AI mania.
- The engine now handles the complete WASM specification and bundles working builds of MicroPython, QuickJS, and Micro QuickJS via PyPI.
Context
The article describes a 'vibe-coded' project where the author used Claude Opus 5.5 to evaluate and improve the engine. The project's success represents a significant improvement over a 10-month-old version, though the author remains skeptical of the tool's reliability.
Limitations
The evidence is a single article from October 2026 with no further supporting data. The author explicitly states they would not trust the engine at all, and the article does not provide specific performance benchmarks, user statistics, or detailed technical specifications beyond the existence of bundled libraries.
