ArrowJS

ArrowJS is a reactive UI framework built on JavaScript primitives like modules, functions, and template literals, solving the problem of building fast, maintainable applications without a build step. It targets developers and engineering teams, especially those building with coding agents, and is positioned as a tiny, zero-dependency, type-safe framework that runs in the browser with no compilation required. It also offers a sandbox for isolating component logic in Web Assembly, making it suitable for on-demand UIs generated by chat agents.
