MUI started with Material UI, the most successful React implementation of Google's Material Design. We have gained a large following, thanks to our focus on Material Design fidelity, our obsession with details, on offering a large number of components, our community engagement, and by carefully improving the DX. Today, countless teams and organizations rely on our open-source libraries to build their design system.
A couple of years ago, we started to expand our suite of products. We released MUI X, a collection of advanced components; MUI Design kits, the MUI components available for Figma, Sketch, etc.; and also host Templates, a set of pre-built UI kits. We've seen rapid growth with all of them (2-3x per year) and we have more to come. We are building a low-code platform for developers to significantly increase the speed and lower the barrier for creating simple CRUD/dashboard UIs with MUI.
We are a fully distributed team, spread across multiple time zones. We work mainly asynchronously, relying mostly on written collaboration. Every contributor has the freedom to define how they work — the rest of us won't know what you're doing day-to-day unless you tell us. For additional details about the MUI team and culture, you can check our careers and about pages and also our public Handbook.
