A guide to Mantine, a React component library with ready-made interface elements and hooks. React is a JavaScript library for building user interfaces, and Mantine also covers forms, themes, dark mode, and charts.

Use it when building React interfaces, configuring themes or dark mode, creating forms, using reusable components, or adding charts and date controls.

It helps you build common interface parts without designing every control from scratch. It also explains setup and customization for React applications using TypeScript and CSS modules.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00079	$0.02550
Opus 5.5	$0.00032	$0.01020
Sonnet 5.5	$0.00016	$0.00510
Haiku 4.5	$0.00008	$0.00255

Security

Grade A, and why

mantine-dev scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 24d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Mantine UI Library

Mantine is a fully-featured React components library with TypeScript support. It provides 100+ hooks and components with native dark mode, CSS-in-JS via CSS modules, and excellent accessibility.

v9.6 Highlights

New @mantine/lightbox package: full-screen media lightbox with carousel navigation, zoom, thumbnails, video and custom slides, and a store-based API (mount once, open from anywhere, same pattern as Spotlight and Notifications).
New ActionBar component: a floating selection-action bar that hosts bulk actions for selected items (for example, selected table rows).
@mantine/charts adds GaugeChart, WaffleChart, MatrixChart, and CandlestickChart; area/bar/line/composite/scatter charts gain referenceAreas and referenceDots; AreaChart gains type="stream"; ScatterChart gains a right Y axis.
@mantine/tiptap RichTextEditor gains table controls, a collapsible Details control, and an InvisibleCharacters formatting-marks control (register the matching Tiptap extensions); Typography now styles details/summary elements.
Notifications gains renderNotification to replace the default notification with fully custom content while keeping enter/exit/drag-dismiss animations.
@mantine/schedule: ResourcesMonthView supports event resizing, time-grid views support configurable drag/resize snap intervals, background events can be interactive, and YearView gains renderDay and withWeekendDays.
Dropzone upgrades to react-dropzone 20 (partial-accept maxFiles behavior, stricter FileWithPath). Node.js 22 or later is now required (Node 20 reached end of life in April 2026).

v9.5 Highlights

New Cascader component: select a value from hierarchical data by drilling down through cascading columns, with changeOnSelect, hover-to-expand, search, and a flat-list layout for mobile.
@mantine/charts gains SunburstChart (hierarchical data as concentric rings) and BulletChart (a value against a target and qualitative ranges); the area/bar/line/composite charts add withBrush for a draggable range-selector, and every chart component now ships accessibilityLayer (arrow-key navigation, Enter for tooltips) enabled by default.
Calendar-based date components gain withNativeLevelSelect, replacing the calendar header's level button with native <select> elements, paired with yearsSelectRange.
Timeline.Item gains opposite (content on the other side of the line, switching to a centered two-sided layout) and alternate (flips sides per item); FloatingWindow gains a ResizeHandle compound component with a dimensions prop and keyboard resizing; Modal/Drawer gain keepMountedMode ('activity' or 'display-none'); Accordion gains disableCollapse to keep one item always open.
@mantine/schedule ResourcesDayView/ResourcesWeekView accept intervalMinutes greater than 60 for multi-hour slot columns.
9.5.0 fixes an autoClose timer leak in the notifications container.
The official Vite template replaced ESLint/Prettier/eslint-config-mantine with oxlint/oxfmt via the new oxc-config-mantine package (internal tooling migration); eslint-config-mantine remains available for projects that keep ESLint.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
