Answered from the vendors’ own pages

MUI: Is MUI free?

The core library is open source and free. Advanced components, including the full-featured data grid, require a paid licence.

Yes, Prettier is completely free and open source, available as an npm package with no licensing costs or subscriptions.

MUI: Can MUI look non-Material?

Yes, through the theming system, but a substantial departure takes real work. Teams wanting full design control often prefer unstyled primitives instead.

Prettier: Can Prettier be integrated with ESLint?

Yes, Prettier integrates with ESLint by disabling ESLint formatting rules via eslint-config-prettier, allowing both tools to work together with Prettier handling formatting and ESLint handling code quality.

Source
MUI: Does MUI handle accessibility?

Components follow WAI-ARIA patterns by default, which is a large part of why teams adopt it.

Prettier: Does Prettier support configuration customization?

Prettier is intentionally opinionated with limited configuration options to enforce consistency. You can create a .prettierrc file for basic customization, but Prettier does not support extensive rule customization like ESLint.
