LocalMode UI

What It Does

LocalMode UI is a comprehensive component library of 100+ React components and 36 installable blocks specifically designed for building AI applications that run entirely in the browser. It enables developers to create sophisticated AI experiences—including chat interfaces, RAG systems, vision capabilities, audio processing, and agent workflows—without requiring servers, API keys, or cloud infrastructure. All AI inference happens on-device using WebGPU or WebAssembly.

Who It's For

LocalMode UI targets developers building privacy-focused, offline-capable AI applications. It's ideal for teams who want the developer experience of shadcn/ui but for AI components, and for projects where data sovereignty, offline operation, or zero backend costs are critical requirements. Whether you're building a personal productivity tool, an enterprise application with strict data policies, or experimenting with edge AI, LocalMode UI provides production-ready components.

Key Features & Capabilities

• 100+ specialized components across Conversation, Local-First, Audio, Results, Input Controls, Media & Vision, Data & Documents, Artifacts, Security & Privacy, and DevTools categories
• 36 installable blocks including Chat, RAG Chat, Object Detector, Voice Notes, Image Search, PII Redactor, and Writing Tools—each running real models entirely in-browser
• True local-first architecture: inference via WebGPU (Chrome/Edge 113+, Safari 26+) or WebAssembly fallback, with no network requests after initial model download
• Copy-owned components that inherit your existing shadcn/ui theme and configuration
• PWA-ready with offline support and installable experiences
• Privacy by default: data never leaves the device, no telemetry, no API keys required

Installation & Workflow

Install components using the familiar shadcn CLI pattern: configure the @localmode namespace in your components.json, then run npx shadcn@latest add @localmode/ui/<component-name>. Components integrate seamlessly into existing React/Next.js projects and work with your current design system. The Blocks gallery provides complete, runnable examples that demonstrate real model integration patterns you can immediately adapt.

What Makes It Different

Unlike cloud-based AI component libraries, LocalMode UI prioritizes privacy, offline capability, and zero ongoing costs. It eliminates API dependencies, latency, and usage fees while giving users complete control over their data. The library is MIT-licensed, fully open source, and designed to be both browser-compatible and cloud-extensible when needed.
