ArrowJS: Type-safe, zero-build UI sandboxes—blazingly fast, tiny.
Best product for this task
ArrowJS
dev-tools
ArrowJS is a tiny, type-safe reactive UI framework that runs without a build step and stays under 5kb. It isolates agent-generated logic in WebAssembly sandboxes while rendering full inline DOM, making it ideal for safe, flexible, agentic interfaces and fast, maintainable web frontends.
What to expect from an ideal product
- Skip the build process entirely by running ArrowJS directly in the browser, cutting out webpack, bundlers, and compilation steps that bloat your application size
- Get full TypeScript support without heavy tooling overhead, catching errors during development while keeping the final bundle extremely lightweight
- Use reactive DOM updates that only change what's actually different, avoiding the performance penalties of virtual DOM diffing found in larger frameworks
- Isolate complex UI logic in WebAssembly containers that protect your main application from potentially unsafe code while maintaining blazing speed
- Write components with inline DOM rendering that gives you complete control over markup without sacrificing the small footprint or type checking benefits
