Lumeo Blazor Component Library
“The Blazor component library you'd actually want to ship — 145 components across a modular core and opt-in satellites.”
Why Lumeo Exists
Blazor needed a modern, design-first component library that feels as polished as shadcn/ui for React — purpose-built for the .NET ecosystem.
Lumeo ships production-grade primitives across a modular core: 145 components, structured so you only pull in what you actually build with.
.NET developers wanted native Tailwind CSS v4 integration, dark mode out of the box, runtime theming, and copy-paste examples. Lumeo delivers all of it as a single, idiomatic Blazor library.
From DataGrid and Charts to AI chat primitives, motion, scheduler and Gantt — production-ready since v1.0, refined through v2.2.0, and evolving with every release.
Install in 30 seconds.
Pick the path that fits your workflow. All three install the same library.
Add what you need.
$ dotnet add package Lumeo
$ dotnet add package Lumeo.Charts
builder.Services.AddLumeo();Start with the core, then opt into Charts, DataGrid, Editor, Motion, Scheduler or Gantt as you need them.
Scaffold from scratch.
$ dotnet tool install -g Lumeo.Cli
$ lumeo initThe Lumeo CLI bootstraps a new Blazor project with components, theming, and routing wired up.
Start with a real app.
$ dotnet new install Lumeo.Templates
$ dotnet new lumeo-appProduction templates: dashboards, SaaS apps, marketing sites — all built on the same primitives.
One core. Opt-in satellites.
Bundle only what you ship. Every package is independently versioned, AOT-friendly, and Brotli-compressed.
Core primitives, forms, navigation, overlays, theming.
30+ chart types via Apache ECharts.
Virtualized grid with sorting, filtering, export.
Rich text editor with collaborative-ready primitives.
Scroll-driven animations: BlurFade, BorderBeam, Marquee.
Resource scheduler with drag-and-drop.
Gantt chart with dependencies and milestones.
Built for the apps you're actually building.
DataGrid · Kanban · Gantt
Production-grade DataGrid with sorting, filtering, virtual scrolling. Scheduler and Gantt as opt-in packages for project apps.
30+ Chart Types (ECharts)
AOT-friendly Apache ECharts integration. Bar, line, area, pie, radar, sankey, treemap, heatmap, candlestick, waterfall, sparklines.
AI Primitives
Streaming messages, chat composers, prompt input and tool-call rendering — drop-in components for AI surfaces.
Motion Primitives
BlurFade, BorderBeam, Marquee. Scroll-driven animations without writing keyframes.
8 Theme Presets · Tailwind v4
CSS-variable theming. Switch themes at runtime. No hardcoded dark: prefixes — just clean tokens.
MCP Server · Source Generator
AI agents read and modify components via the bundled MCP server. Source generator produces compile-time theme helpers.
