Browser Hub Demo
WebAssembly
WebAssembly gives browser-native tools a path to reuse serious compute code without forcing every heavy job through a server. It is especially useful when paired with OPFS, WebCodecs, WebGPU, and worker rendering.
Portable compute
What this unlocks
Run compact compiled modules in the browser for fast local processing, parsers, transforms, compression, and analysis workflows. Broadly supported in modern browsers. Advanced features such as threads, SIMD, component-model workflows, and streaming compilation still need capability checks and fallbacks.
Use cases
Real product scenarios
These are the kinds of workflows where the API earns its complexity.
Run local parsers, validators, compression, or export preparation in Production Studio.
WebAssembly helps when the browser needs to move beyond plain navigation and forms.
Process larger files that stay in OPFS until the user explicitly exports them.
WebAssembly helps when the browser needs to move beyond plain navigation and forms.
Bring mature native libraries into browser tools with careful sandboxing and fallbacks.

Shipping notes
Progressive enhancement rules
Browser capability work is product design work. Support levels, permissions, secure context requirements, and fallback behavior matter as much as the demo itself.
Treat third-party modules as supply-chain sensitive dependencies.

Keep compute jobs user-triggered, bounded, and cancelable.

Expose clear fallback paths for browsers or devices that lack the required advanced features.
