The team ported the Claude Code source code to the WebAssembly runtime, bundling Node.js and Python, and achieved running Claude Code directly in the browser, including a terminal UI and a local-like isolated execution environment.
Capsule Bash is a sandboxed Bash environment for AI agents, offering secure WebAssembly-based isolation and enriched command feedback without complex setup.
Hoot 0.9.0, a Scheme to WebAssembly compiler backend for Guile, has been released with new features and bug fixes, including DWARF support, standard Wasm exceptions, and a game jam template for the Lisp Game Jam.
Met-Shield is an open-source re-entry simulator that uses a Physics-Informed Neural Network (PINN) to predict thermal gradients on a spacecraft shield, integrated into a C++ WebAssembly engine for real-time browser performance. The project addresses robustness over traditional solvers but faces convergence issues during high heat flux phases.
Dart Live enables running the Dart compiler, VM, and analyzer entirely in the browser via WebAssembly, supporting stateful hot reload without a server.
The author compares the compact 35MB size of a WebAssembly-compiled Godot game engine to typical Docker base images, questioning why WASM adoption remains limited despite its significant size and deployment advantages.
This blog post responds to the claim that WebAssembly is not a pure stack machine by discussing its design with locals and comparing it to Forth, arguing that it still fits the definition of a stack machine and that its register-like locals improve readability and performance.
A guide to using Chrome DevTools for debugging WebAssembly code, including setting breakpoints and catching exceptions.
A new open-source WebAssembly-based emulator for the 1980s Plexus P/20 Unix server, letting users run SystemV Unix in the browser.
Interactive WebAssembly-based demo for SQLite Query Result Formatter that allows users to format SQL query results in 20+ styles including tables, CSV, JSON, HTML, and Markdown with real-time adjustments.
watgo is a pure Go WebAssembly toolkit that can parse WAT, validate, encode to WASM binary, and decode binary format, with both CLI and Go API.
Wasmer used OpenAI Codex to build a C++ JavaScript runtime for edge WebAssembly in two weeks—work they estimate would have taken a year—turning the model into an autonomous teammate that debugs and largely replaces traditional IDE use.
