About Elefunc, Inc.

Elemental functions
for a real-time web.

We champion the open web and its ever-evolving, standards-based APIs.

At Elefunc, we've made a strategic decision to break free from proprietary, single-company frameworks like Angular, Vue, or React. Our focus is on unlocking the full potential of native web platform APIs, ensuring our products and services are built on a foundation of cutting-edge, universal technologies. This approach guarantees that our tools remain evergreen, flexible, and adaptable to the rapidly evolving digital landscape.

Our methodology offers developers unparalleled simplicity, immediacy, transparency, control, and stability - qualities often compromised in framework-dependent environments. By embracing native APIs, we foster a deeper understanding of web technologies, igniting creativity and driving innovation.

We're not just creating tools and services; we're forging a stronger connection to the web and its fundamental functions. Our unwavering commitment to the open, standards-based web platform is what sets Elefunc and our products apart. Join us in harnessing the raw power of the web to build extraordinary digital experiences.
