Deep dive: shadcn/ui
When to choose shadcn/ui
shadcn/ui is the right choice when the team wants high-quality, accessible React components without the constraints of a traditional component library. Unlike Chakra UI or Material UI, shadcn/ui copies component source code into the project rather than installing an npm package. This means the team owns every line of code, can modify components freely, and never faces breaking changes from library upgrades. It is built on Radix UI primitives for accessibility and Tailwind CSS for styling. shadcn/ui fits projects where design customization is non-negotiable and the team is already using Tailwind. It is a weaker choice for teams that want a complete design system out of the box with minimal configuration, teams not using Tailwind CSS, or projects that need consistent cross-project component updates pushed via npm version bumps.
Real-world use case
A B2B SaaS startup building a dashboard with 40+ unique views chooses shadcn/ui because the design team needs full control over component styling without fighting library overrides. The team installs 22 shadcn components via the CLI, customizes the color tokens in globals.css, and modifies the Dialog component to add a custom animation. When a new design requirement arrives for a data table with inline editing, the team extends the shadcn Table component directly rather than working around library constraints. The tradeoff: component updates from the shadcn repository do not propagate automatically. When a Radix UI accessibility fix lands upstream, the team must manually diff and apply the change to their local copy, which they discover 3 months late after a user reports a screen reader issue.
Hidden gotchas
The copy-paste model means the team is responsible for keeping Radix UI dependencies updated. shadcn components pin specific Radix versions, and Radix releases sometimes change prop names or behavior. A Radix upgrade can break 10 shadcn components at once if the team updates the dependency without checking each component. The CLI (npx shadcn-ui add) generates components with specific import paths that assume a particular project structure (components/ui/). Moving components to a different directory requires updating every import across the project. Tailwind CSS v4 changed the configuration format significantly, and shadcn components generated for Tailwind v3 need manual migration. The theming system uses CSS custom properties mapped to HSL values, and switching to a different color space (like OKLCH) requires rewriting the entire theme layer. Teams that add many shadcn components accumulate 2,000+ lines of UI code in their project that they now maintain, which can feel like a liability when the original shadcn patterns evolve and the team's copies diverge.
Pricing breakdown
shadcn/ui is completely free and open-source. It is not a traditional npm package — you copy component source code directly into your project. There are no paid tiers, pro components, or premium themes from the official project. The total cost is $0. The cost advantage over commercial UI libraries like Chakra UI Pro ($149-349) or Tailwind UI ($299): identical quality components with full source ownership and zero licensing fees. The tradeoff: you maintain the components yourself — updates require manually re-copying from the shadcn/ui registry or using the CLI to update.
Deep dive: Mantine
When to choose Mantine
Mantine is the right choice when the team wants a comprehensive React component library that goes beyond basic UI primitives to include hooks, form management, notifications, rich text editing, and date pickers in a single package. Mantine ships 100+ components and 60+ hooks, making it one of the most feature-complete React UI libraries available. It uses CSS modules instead of CSS-in-JS, which makes it compatible with React Server Components and avoids the runtime style injection overhead of Emotion or styled-components. Mantine fits teams that want a single dependency for most UI needs rather than assembling components from 5 different libraries. It is a weaker fit for teams that want unstyled primitives for maximum design control or teams already invested in Tailwind CSS (Mantine uses its own styling system).
Real-world use case
A developer tools company building a SaaS dashboard with complex forms, data tables, date range pickers, and rich text editing chooses Mantine because a single import covers all of these use cases. The team uses Mantine's form hook for 12 multi-step forms with cross-field validation, the RichTextEditor for a template builder, and the DateRangePicker for analytics filters. Without Mantine, these would require React Hook Form + TipTap + react-day-picker + a notification library + a separate component library — 5 dependencies with different styling conventions. The tradeoff: Mantine's opinionated design means the team cannot easily mix and match with Tailwind-styled components from other libraries without visual inconsistency, and the total bundle size is larger than using individual lightweight alternatives for each feature.
Hidden gotchas
Mantine v7 dropped CSS-in-JS entirely and moved to CSS modules, which is a major breaking change from v6. Every createStyles call and sx prop must be rewritten. The migration guide is thorough but the actual work for a large application (100+ component files) takes 1-2 weeks. Mantine's CSS module approach generates class names at build time, which means dynamic styles that depend on runtime values need to use inline styles or CSS custom properties rather than the old sx prop pattern. The RichTextEditor component wraps TipTap and inherits its bundle size (50+ KB gzipped). Teams that only need basic text formatting would be better served by a lighter alternative, but Mantine bundles it as an optional package rather than lazy-loading it. Server-side rendering with Mantine requires the MantineProvider and ColorSchemeScript in the root layout, and missing either causes hydration mismatches that manifest as flash-of-unstyled-content. The Notifications system uses a global state manager that conflicts with some state management libraries if both try to manage the notification queue.
Pricing breakdown
Mantine is completely free and open-source under the MIT license. There are no paid tiers, pro components, or premium features. The library includes 100+ components, 50+ hooks, and a rich text editor — all free. The total cost is $0 at any scale. The cost advantage: Mantine includes components (date pickers, rich text editor, notifications, carousel) that other libraries either lack or charge for. Mantine is maintained by one developer (Vitaly Rtishchev) with sponsorship funding. The risk: single-maintainer dependency, though the codebase is well-structured enough for community forks.
Should You Use shadcn/ui or Mantine?
For most teams, shadcn/ui is the better default: it offers you own the code and is open-source (from $0). Choose Mantine instead if most complete out-of-the-box matters more than copy-paste model means more code in repo. There is no universal winner — the right pick depends on your budget, team size, and whether you value you own the code or most complete out-of-the-box more.
Choose shadcn/ui if…
- •You own the code
- •Beautiful default design
- •Accessible (Radix)
Choose Mantine if…
- •Most complete out-of-the-box
- •Excellent hooks
- •Good documentation
