Bootstrap 5 vs Materialize CSS — Material Design vs Bootstrap in 2026

Materialize CSS had a clear pitch: bring Google's Material Design to any web project without a JavaScript framework. Nice ripple effects, cards that looked like the Google ecosystem, a grid system, modals — all with Material Design aesthetics.

It was popular from roughly 2015 to 2018. Then Material Design itself changed, the framework didn't keep pace and the community moved elsewhere.

The Material Design Framework Problem

Here's the fundamental issue with Materialize CSS: Google itself moved away from the "Material Design for the web via a CSS framework" approach. Google's own web properties don't use Materialize CSS. The actual maintained implementations of Material Design are:

• Material UI (MUI) for React
• Angular Material for Angular
• Material Web — Google's own web components

Materialize CSS was a third-party interpretation of Material Design that Google was never involved in. When Material Design 2 and then Material You (M3) came out with significant design changes, Materialize didn't keep up.

Technical Comparison

Maintenance: Bootstrap 5.3 is actively developed. Materialize CSS hasn't had a meaningful release in years. This alone should end the decision for most projects.

jQuery: Materialize requires jQuery. Bootstrap 5 dropped jQuery entirely.

Components: Bootstrap's component library is larger and better documented. Materialize had some nice components — the floating action button, ripple effects, timeline — but the coverage overall doesn't match Bootstrap 5.

Dark mode: Bootstrap 5.3 has native dark mode via data-bs-theme. Materialize has no equivalent.

CSS variables: Bootstrap 5.2+ uses CSS custom properties extensively for theming. Materialize doesn't have this.

Customisation: Bootstrap's Sass variable system lets you override the design system before compilation. Materialize's customisation is more limited.

Who Should Consider Materialize CSS

Nobody starting a new project in 2026. The maintenance situation alone is disqualifying.

If you have an existing Materialize CSS project: if it's working and not causing problems, leave it. If you need significant new features or are hitting bugs, plan a migration to Bootstrap 5 or — if you need Material Design specifically — to MUI or Angular Material.

The Honest Summary

Materialize CSS served a purpose in 2015 when Material Design was new and exciting and there wasn't a clean way to get it without Angular. That gap no longer exists. MUI and Angular Material are polished, actively maintained and deeply integrated with their respective frameworks.

Bootstrap 5 wins if you don't specifically need Material Design. MUI or Angular Material win if you do. Materialize CSS wins nothing in 2026.
