RusticUI

Enterprise-grade UI components for Rust. Material UI for Rust with responsive layouts, accessibility, WebAssembly targets, and observability.

Request Demo

RusticUI is an enterprise-grade UI components library for Rust, continuing the Material UI for Rust initiative. It provides responsive layout primitives (Box, Container, Grid), design system macros for consistent theming, and accessibility-forward components with ARIA markers. Designed for WebAssembly targets today with native rendering planned for the future.

Built with automation, observability, and platform-neutral APIs at its core, RusticUI offers deterministic focus management, disclosure primitives, and comprehensive tooling (cargo xtask, Makefile automation). Telemetry integration enables performance monitoring of UI components. Ideal for developers building cross-platform interfaces, medical device UIs, embedded systems, or high-performance web apps using Rust and WebAssembly.

Key Benefits

  • Rust-first - Type-safe, memory-safe UI components with zero-cost abstractions
  • Material UI for Rust - Familiar Material Design patterns adapted for Rust
  • WebAssembly targets - Compile to Wasm and run in browsers or server-side rendering
  • Accessibility-forward - ARIA labels, keyboard navigation, screen reader support
  • Responsive primitives - Box, Container, Grid for flexible layouts
  • Design system macros - Consistent theming with compile-time guarantees
  • Observability built-in - Telemetry hooks for performance monitoring

Responsive Layout Primitives

Foundational components for building responsive layouts: Box (flex container), Container (max-width wrapper), Grid (CSS Grid layout). Breakpoints for mobile, tablet, desktop, ultra-wide. Stack (vertical/horizontal), Spacer, Divider for common layout patterns.

Design System Macros

Compile-time macros for defining design tokens (colors, spacing, typography, shadows). Enforce consistency across components with type-checked theme variants. Light/dark mode support with automatic color adjustments. Custom themes per brand or tenant.

Accessibility-Forward Design

All components ship with ARIA labels, roles, and states. Keyboard navigation (Tab, Enter, Escape, arrow keys) built-in. Screen reader support with live region announcements. Focus management with deterministic focus traps and restoration. WCAG 2.1 AA compliant.

WebAssembly Targets

Compile RusticUI components to WebAssembly and run in browsers, Node.js, or edge runtimes. Near-native performance with small bundle sizes. Server-side rendering (SSR) for static HTML generation. Future: native rendering for desktop and mobile (planned).

Deterministic Focus & Disclosure

Predictable focus behavior for modals, dropdowns, and overlays. Focus traps prevent keyboard navigation outside active components. Disclosure primitives (Accordion, Tabs, Dropdown) with automatic ARIA attributes. Focus restoration when components unmount.

Observability & Telemetry

Built-in telemetry hooks for tracking component render time, interaction latency, and error rates. Export metrics to Prometheus, Datadog, or custom backends. Debug performance bottlenecks in production. Trace component lifecycle events (mount, update, unmount).

Comprehensive Tooling:

  • cargo xtask - Custom build tasks (compile to Wasm, run tests, generate docs)
  • Makefile Automation - One-command builds, tests, benchmarks, and releases
  • Hot Reload - Live reload during development (Wasm targets)
  • Component Storybook - Visual component explorer with live props editing
  • TypeScript Types - Auto-generated TypeScript definitions for Wasm bindings

Platform Neutrality:

  • Web - Compile to Wasm and run in browsers (Chrome, Firefox, Safari, Edge)
  • Server - Run in Node.js or Deno for server-side rendering
  • Edge - Deploy to Cloudflare Workers, Fastly Compute@Edge
  • Native (Future) - Desktop (Windows, macOS, Linux) and mobile (iOS, Android) rendering

Healthcare

Build cross-platform user interfaces for medical devices (infusion pumps, monitors) or patient portals. Strong accessibility (WCAG compliance) and predictable focus management ensure usability for all patients. Compile to Wasm for embedded systems or web portals.

Automotive Retail

Create high-performance dealer websites or in-car dashboards using WebAssembly. Responsive layouts adapt to desktop, tablet, and in-vehicle displays. Near-native performance for interactive configurators and real-time inventory updates.

Financial Services

Develop secure trading dashboards with deterministic UI behavior (critical for compliance). Observability hooks enable performance monitoring for latency-sensitive applications. Compile to Wasm for zero-trust execution in sandboxed environments.

Legal

Construct document review interfaces with accessible navigation and theme consistency. Integrate telemetric analytics to track user workflows and optimize UX. WebAssembly targets enable secure client-side document processing.

Government

Build citizen portals and interactive maps using Rust for safety and performance. Support multilingual theming (i18n) for diverse populations. Accessibility features ensure compliance with Section 508 and WCAG standards.

Military & Intelligence

Develop simulation or command-and-control interfaces running in secure sandboxes (WebAssembly isolation). Platform neutrality enables cross-domain deployment (web, desktop, embedded). Observability hooks provide real-time performance metrics for mission-critical UIs.

RusticUI is built on the AIOS ecosystem and integrates deeply with other Apotheon products:

  • AIOS (AI Operating System) - RusticUI components compile to Wasm and run on AIOS for zero-trust execution. Telemetry integrates with AIOS observability stack.
  • Morpheus (WebAssembly Plugins) - RusticUI is used to build UI plugins for Morpheus's plugin host. Compile Rust UIs to Wasm and run in Morpheus sandbox.
  • Proteus (Admin Dashboard) - Some Proteus components are implemented with RusticUI for performance-critical UI (data tables, real-time charts) compiled to WebAssembly.
  • Thea (CMS) - RusticUI powers Thea's design system and theming framework. Custom Thea themes use RusticUI macros for compile-time consistency.
  • THEMIS (Governance) - UI component interactions (button clicks, form submissions) are logged in THEMIS's audit trail via RusticUI telemetry hooks.
  • Hermes (Agent Orchestration) - RusticUI components can render agent workflow status, execution logs, and real-time metrics from Hermes.
  • Language: Rust (stable channel, MSRV 1.70+)
  • Targets: wasm32-unknown-unknown (WebAssembly), native (future)
  • Rendering: Virtual DOM (custom), Canvas API, WebGL (future WebGPU)
  • Design System: Material UI patterns, compile-time theme macros
  • Layout: Flexbox, CSS Grid via Rust APIs
  • Accessibility: ARIA attributes, keyboard navigation, screen reader support
  • Telemetry: Custom hooks, OpenTelemetry integration
  • Tooling: cargo xtask, Makefile, wasm-pack, wasm-bindgen
  • Package Manager: crates.io, npm (for Wasm bindings)
  • Bundle Size: ~50KB (gzipped) for base components
  • Performance: 60+ FPS for complex UIs, sub-10ms render time
