MiniDev UI vs Mantine: which should you use?

What each one is

Mantine is a fully featured React component library maintained by Vitaly Rtishchev and hundreds of contributors. The core package covers inputs, overlays, navigation, layout and data display, and a family of separate packages adds a form library, date pickers, charts built on Recharts, a notifications system, a spotlight command center, a rich text editor based on Tiptap, a carousel and more. Styles ship as regular CSS files, so there is no runtime styling cost, and you customize components with CSS modules, the Styles API or style props. Everything is MIT and free.

MiniDev UI is a free, MIT licensed shadcn-compatible registry of over 500 items built on Base UI, Tailwind CSS v4 and motion. You add items with the shadcn CLI and the source lands in your repo. Its focus is product screens: data tables, billing and invoice pages, settings layouts, command palettes, notification centers and AI chat, plus about 43 full-page blocks and 86 motion components under one token system.

Where Mantine shines

• Breadth in one dependency. Components, 70+ hooks, forms, dates and charts come from one maintainer with one API style, so pieces fit together.
• Forms and dates. @mantine/form handles form state and validation, and @mantine/dates provides date and time pickers, both designed to work with the core inputs.
• No Tailwind required. Teams that prefer CSS modules or plain CSS get a complete system without adopting utility classes.
• Stable releases. Mantine documents a regular cadence of patch, minor and major versions and keeps docs for previous versions online.
• Free extras. The Mantine UI site offers 123 free prebuilt components, and the docs publish llms.txt files and an MCP server for AI tools.

Where MiniDev UI shines

• Tailwind native. If your codebase is already on Tailwind CSS v4, MiniDev components use the same utilities and tokens as the rest of your UI.
• You own the code. Every component is a file in your repo, so changes are edits rather than overrides through a styles API.
• Finished screens. About 43 blocks and pages, from sign in to an admin console, give you a working screen to adapt.
• A visual system. One light source drives shadows, and a data-material attribute switches between hairline, glass, metal and paper.
• Motion included. About 86 motion components built on motion share the same tokens as the UI.

Using them together or migrating

Running both in one app is possible but means two styling systems. Mantine's help center says that disabling Tailwind's preflight is usually enough to keep global styles from affecting Mantine components; if you need preflight, see the guides linked from their help page. MiniDev UI expects Tailwind's base styles, so a mixed app needs some care. In practice, a clean split works better: keep Mantine in an existing app and use MiniDev UI for a new Tailwind surface, such as a marketing site or a separate dashboard.

When moving from Mantine to MiniDev UI, migrate a route at a time. Mantine's MantineProvider, theme object and hooks do not carry over, so map your theme colors to MiniDev's semantic tokens first. Mantine hooks are standalone, so @mantine/hooks can stay in the project while you replace components. Form and date logic usually needs the most attention, since MiniDev UI provides the input components and a form wizard but not a separate form state library.

Which to pick

• Choose Mantine if you want one well documented package for nearly everything, especially forms and dates, and you do not want Tailwind.
• Choose MiniDev UI if your project uses Tailwind CSS v4 and you want editable source, product screens and full-page blocks.
• Keep them separate if you need both: one per app or surface is simpler than mixing two styling systems on the same page.
