Mediator

A mediator pattern implementation built for all .NET apps — mobile, desktop, and server. Source-generated, AOT-ready, and packed with middleware that lets you add offline support, caching, validation, resiliency, and more with a single attribute.

Decouple your code, shrink your constructors, and eliminate boilerplate. Works seamlessly with MAUI, Blazor, Uno Platform, ASP.NET Core, Prism, and Dapper.

MAUI Toolkit

Purpose-built components for .NET MAUI that fill the gaps the framework leaves behind.

Shell — Opinionated Shell navigation with source-generated routes, strongly-typed parameters, and proper ViewModel lifecycle management. No more magic strings or manual wiring.

Scheduler — Calendar, agenda timeline, and event list views with a shared data provider interface. Monthly grid, multi-day timeline with overlap detection and timezone support, and infinite-scrolling event list — all AOT-safe with custom DataTemplate support.

TableView — A pure MAUI settings-style TableView with 14 cell types, cascading styles, drag-to-sort, sections, and full MVVM support. Build polished settings pages in minutes.

Contact Store — Cross-platform device contact access with full CRUD, LINQ queries with native translation, and MAUI permission classes. Read, create, update, and delete contacts on Android and iOS.

Mermaid Diagrams — Native Mermaid flowchart rendering using pure MAUI Graphics. Hand-written parser, Sugiyama layout algorithm, 4 built-in themes, and pan/zoom gestures — no WebView or JavaScript required.

Data

Lightweight, AOT-compatible data libraries that run everywhere .NET does — no ORM overhead.

Document DB — Store and query .NET objects as JSON documents with full CRUD, LINQ-style querying, projections, aggregates, and transactions. Supports SQLite, SQL Server, MySQL, and PostgreSQL with a single API.

Spatial — A dependency-free spatial database using SQLite R*Tree indexing and custom geometry algorithms. Ship pre-built datasets or build your own geospatial queries.

Extensions

A collection of source generators and utilities that cut boilerplate and boost performance across any .NET project.

Dependency Injection — Attribute-driven DI registration with source generation. Tag your classes, generate your registrations, done.
Stores — A cross-platform key/value store abstraction for Preferences, Secure Storage, Local/Session Storage, and more.
Reflector — Source-generated property access that eliminates reflection for AOT-safe, high-performance code.
Localization Generator — Strongly-typed classes generated from your .resx files. No more typo-prone string lookups.
MAUI Hosting — Modular MAUI app configuration with IMauiModule, static service access, and platform lifecycle dispatch.
Web Hosting — ASP.NET infrastructure modules for common server-side patterns.

Aspire

First-class .NET Aspire integrations for building distributed applications with best-practice defaults.

Orleans — Simplified Orleans hosting for Aspire with streamlined AppHost configuration, Silo setup, and client wiring. Get a fully orchestrated Orleans cluster running in your Aspire app with minimal code.

Gluetun VPN — Model a Gluetun VPN container as a first-class Aspire resource. Route other containers through the VPN tunnel with a single method call, with full Docker Compose publish support.

Templates

Skip the setup and start building. Shiny.Templates scaffolds a fully configured .NET MAUI app with all the Shiny libraries, 40+ curated 3rd party packages, and every platform-specific file already wired up — permissions, plists, entitlements, DI, logging, and more.

Choose your UI markup (XAML, Blazor, or C# Markup), authentication provider, push notification backend, and you’re ready to go.

dotnet new install Shiny.Templates

AI Coding Assistant Skills

Get contextual code generation and best practices directly in your IDE

Every Shiny library has an AI skill that understands its APIs, patterns, and conventions. These skills work with Claude Code and GitHub Copilot to help you scaffold projects, generate code, and follow best practices.

claude plugin add github:shinyorg/skills

Browse the skills repository and open the skill file you need
In your repository, create .github/copilot-instructions.md if it doesn't exist
Paste the skill content into that file and save

Copilot will automatically pick up the instructions on your next chat or code completion. You can also use path-specific instructions by placing the file in .github/instructions/ with an applyTo frontmatter pattern.

Companies building real products with Shiny.NET

SpeedyDock is an essential application for drystack marinas, boat clubs, and their clientele, streamlining the process of scheduling and monitoring boat launch requests, reservations, and additional services. It offers a user-friendly alternative to the frequent calls customers used to make, enabling electronic scheduling around the clock. Since its initial release in 2016, SpeedyDock has been accessible across iOS, Android, and web platforms, seamlessly integrating Xamarin and Shiny to manage native functionalities.

A core component of SpeedyDock’s efficiency is Shiny. It powers the app’s capability to work with permissions requests, local notifications, geofencing, and Firebase push, ensuring customers are consistently informed about their request statuses. For marina operators, these timely notifications are instrumental in enhancing service quality when customers set foot on the premises. Shiny has expertly bridged the gap between iOS and Android, offering a structured way to organize and share code, which, in the absence of such a tool, would be intricate due to variances across platforms and different OS versions. It has streamlined our development process for new features and minimized the edge case bugs typically associated with varying Android versions.

Shiny isn’t just a tool for SpeedyDock; it’s a cornerstone of our mobile app development. Its integration has empowered us to deliver a top-tier app with a native experience. Looking ahead, we’re eager to continue our journey with Shiny, leveraging its capabilities for upcoming projects and refining the SpeedyDock experience. It has undeniably been a key factor in our app’s success story.

— Travis Wolfe, CEO SpeedyDock

PoolMath is the go-to pool care app for hundreds of thousands of pool owners, and Shiny has been a critical part of our stack from the beginning. Running on .NET MAUI across iOS & Android, Shiny handles the native plumbing that would take months to build and maintain on our own. It just works, and it works well.

Beyond PoolMath, I see Shiny’s impact across the entire .NET MAUI ecosystem every day in my role at Microsoft. Shiny fills real gaps in the platform — areas where developers would otherwise be writing fragile, platform-specific code. It’s become one of those libraries that the community leans on because it solves hard problems cleanly, and it’s been instrumental in making .NET MAUI a viable choice for production mobile apps that need serious native integration.

If you’re building a .NET MAUI app and you’re not using Shiny, you’re making your life harder than it needs to be.

— Jonathan Dick, CEO PoolMath & Principal Manager @ Microsoft .NET MAUI

At Moultrie, we build mobile apps that connect hunters and landowners to our cellular trail cameras, feeders, and land management tools. Our apps run on .NET MAUI and lean heavily on several Shiny libraries to deliver the kind of native experience our customers expect — reliable background operations, seamless device communication, and responsive notifications even when cellular connectivity is spotty.

Shiny has been instrumental to our product development. What would have been months of platform-specific work across iOS and Android gets reduced to clean, shared code that we can build on with confidence. The breadth of the library suite means we’re not stitching together a dozen different packages with different conventions — Shiny gives us a cohesive foundation that covers our needs and lets our team focus on the features that matter to our users.

For any team building production .NET MAUI apps that need to go beyond the basics, Shiny is the library suite you want in your toolbox.

— Tommy Baggett, Principal Software Architect, Moultrie
