For: People experimenting with browser-based computation
Worth noticing: The page identifies the workbench as experimental, version 0.3.0, and says it uses WebAssembly and WebGPU.

Field notes

The workbench’s landing page describes a sequence of writing a program, inspecting its structure, and running it in the browser. It names WebAssembly and WebGPU, but does not explain their specific roles or state computational limits. Private projects can hold source code, execution inputs, and notes; saving them requires account creation and email verification.
