MUI review
A broad React UI ecosystem with free foundations and paid advanced components.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MUI is an open-source React UI component ecosystem for developers building production web interfaces. Its products include Material UI, Base UI, MUI System, and MUI X, combining prebuilt Material Design components with theming, CSS utilities, templates, and data-oriented tools. React teams can customize colors, typography, spacing, and component behavior, then extend the system with reusable themed components. The Community plan includes 40+ free components, an MIT license, and community support.
Pricing follows a freemium structure. Pro costs $299 per developer per year and adds MUI X Pro access, 10+ Pro features, Pro support, and a multi-app license. Premium costs $599 per developer per year and includes MUI X Premium access, 5+ Premium features, Premium support, and access to new features first. Enterprise adds priority support, a multi-app license, technical support for all libraries, and a Customer Success Manager. The paid tiers are most relevant when a team needs advanced data or support capabilities beyond the free React library.
MUI also connects design and development workflows through Figma design kits, Figma variables, token-based theme customization, and Sync plugin exports for Figma-to-code theme and component customization. It supports React environments including Next.js, Vite, Remix, and Gatsby, and also lists Sketch, Anima, and Quest integrations. This makes it a strong fit for teams standardizing web interfaces across applications. Teams seeking a collaborative design editor rather than a developer-focused component ecosystem should choose a different category of tool; React teams that need advanced production components and a matching design vocabulary are the clearest fit.
