QuantPlay is a 6-max poker trainer bot built in Python (~1.5 MB) that runs locally in the browser via WebAssembly, featuring multiple bot profiles, hand replay with grading, and a heuristic engine based on game theory. The project grew from an unsuccessful attempt to rank in GTO Wizard's leaderboard but resulted in a measurement-driven system with documented limitations and refuted ideas.
A WebAssembly-based tool enables SQLite database migrations directly in the browser, allowing users to define desired schema and automatically generate migration statements without writing ALTER commands manually.
Wasmer has released Swift bindings for its SDK, enabling iOS 27+ and macOS to run sandboxed Python, Node.js, and FFmpeg applications locally. iOS uses WebKit's WebAssembly engine via a hidden WKWebView, while macOS uses Wasmer's native runtime, with both platforms sharing a unified SwiftPM library and async/await API.
FoxDev Studio revives Microsoft's discontinued FoxPro language with a 64-bit runtime and modern architecture, allowing legacy projects to run without conversion. The new system preserves Visual FoxPro's behavior and file formats while eliminating 32-bit limitations, enabling tables to grow beyond the previous two-gigabyte ceiling.
TypeSafe released Blink, a 452KB decision model in C/WebAssembly that answers structured questions in a single forward pass with no token generation or output decoding. The embeddable runtime has zero allocations during scoring, runs on minimal memory, and builds to a 66KB WebAssembly module for browsers and Node without external dependencies.
Infinite Mac now uses Snow, a Rust-based WebAssembly emulator for early 68K Macintoshes, replacing Mini vMac. Snow offers greater accuracy and enables running A/UX, Apple's late-1980s UNIX/Mac hybrid, alongside classic Mac OS. The migration required custom integrations for hardware limitations, disk images, and dynamic screen configuration.
Infinite Mac now uses Snow, a Rust-based WebAssembly emulator for early 68K Macintoshes, replacing Mini vMac. Snow provides greater accuracy and enables running A/UX, Apple's Unix/Mac hybrid from the late 1980s, while Infinite Mac has added a Floppies library of early Mac software and implemented hardware-accurate features like NuBus graphics cards.
Xaml.io v0.9 is a browser-based IDE for building .NET applications with C# and XAML, now featuring an AI coding agent that can generate complete applications from text prompts. The release includes diff review, one-click web publishing, and AI-assisted WPF migration, demonstrated by an agent autonomously creating a Windows 98 Paint clone in 42 minutes with 3,500 lines of code.
FreeCAD 1.1.3, an open-source parametric 3D CAD modeler, has been compiled to WebAssembly and runs entirely in the browser with its Qt interface, OpenCASCADE kernel, and embedded Python. No installation is required and all work remains local to the user's machine.
Cloudflare has announced that Python Workers, which allow developers to run Python applications in the Cloudflare Workers runtime, are now generally available. Python is now a first-class language on the platform, supporting popular frameworks like FastAPI, Django, and Flask, with seamless integration to Cloudflare services and simplified Python object handling without requiring JavaScript conversion code.
A project converts AVS audio visualizer presets to WebAssembly, with warnings about photosensitive epilepsy risks from rapid flashing lights in some visualizations.
Zephyr RTOS has been ported to WebAssembly, allowing the kernel to run freestanding in a browser with a single wasm32 linear memory. The implementation uses Binaryen's Asyncify for context switching and cooperative interrupts, with virtual time enabling deterministic execution. Multiple test samples including hello_world, synchronization, and semaphore tests pass successfully.
CoyoPedal is a standalone guitar amp and effects pedal built on an ESP32-S3 that runs full-size Neural Amp Modeler captures in real time, featuring a touchscreen UI, effects chain, and preset management. It can load custom amp models from microSD cards and also runs as a browser-based WebAssembly build for trying without hardware.
Blaze is a CPU-based, multithreaded vector graphics rasterizer designed to outperform publicly available libraries by subdividing the screen into intervals and distributing rasterization work across threads, avoiding the single-core bottleneck of traditional scanline rasterizers.
