Today, we're launching our updated UI Kit for React. This release represents a fundamental advancement in how chat interfaces are built, with a completely rebuilt architecture that enables unprecedented design quality and customization flexibility.
Why This Matters
The landscape of chat has evolved. Users now expect sophisticated features they use daily in apps like Slack, WhatsApp, and Telegram. Yet the tools available to developers haven't kept pace. Most solutions force a choice: either spend months building custom components to match these expectations, or settle for basic functionality that feels outdated the moment it ships.
Our new React UI Kit changes this equation. We've rebuilt every component to match the sophistication of modern messaging platforms while maintaining the integration simplicity our developers expect.
Superior Design Through Technical Excellence
V5 represents a complete overhaul of our design implementation. Every component has been refined to deliver premium visual quality while handling complex chat scenarios intelligently. From pixel-perfect rendering to sophisticated state transitions, from platform-specific design adaptations to automatic size adjustments – V5 ensures your chat interface feels as polished as dedicated messaging apps.
Our enhanced visual system delivers fluid animations, intuitive gesture handling, and intelligent layout adaptations across all screen sizes. Whether it's message bubbles with perfect spacing, sophisticated typography for optimal readability, or smooth state transitions – every detail has been carefully crafted to provide a premium chat experience.

Theming and Customization
V5's theming system provides unprecedented control over your chat interface's visual identity. The expanded design token system enables everything from basic brand alignment to complete visual customization. Global theming controls color palettes, typography, spacing, and animations, while component-level styling allows granular control over specific elements.
Our enhanced architecture ensures these customizations maintain visual consistency across your React application. The theming system helps you deliver a cohesive look and feel that aligns with your brand.
