fugue-labs published monty-go, an open-source Go library that embeds Pydantic's Monty Python interpreter compiled to WebAssembly and run via wazero. It lets Go programs execute LLM-generated Python code in an isolated WASM sandbox without containers, CGO, or subprocesses, pausing execution whenever the script calls an external function so Go code can handle it and return control.
Dactyl has detailed how its cross-platform SwiftUI renderer works, describing it as a WebAssembly port of the iOS simulator that lets developers preview and build native apps for iOS, Android and web without a Mac. The system reimplements SwiftUI and related Apple frameworks like Charts, MapKit and ARKit in Swift, compiling apps to Wasm and linking them against Dactyl's own version of SwiftUI instead of Apple's.
A developer released TeXbrain, a free open-source LaTeX editor that runs a WebAssembly port of pdfTeX (via SwiftLaTeX) so documents compile to PDF directly in the browser with no server involved. It also supports opening local project folders, syncing with git, and pushing to GitHub, all within a single browser tab. Packages beyond the common ones bundled with the app are fetched on demand from a TeX Live mirror and cached for offline reuse.
