As real-time digital experiences become essential in everything from video conferencing to AI-powered chat, Cloudflare has launched Cloudflare Realtime, a powerful new solution designed to simplify the development of real-time applications. At the heart of this initiative is RealtimeKit, a full-featured developer toolkit created in collaboration with Dyte.io.
Whether you're building a virtual classroom, interactive live stream, or voice-enabled AI interface, RealtimeKit offers the speed, flexibility, and scalability you need — without months of engineering work.
Building real-time experiences is traditionally complex. Developers face challenges such as:
Inconsistent camera/microphone APIs across platforms
Complicated NAT traversal and connection handling
Need for scalable infrastructure to support low-latency, high-concurrency environments
Integrating AI for speech or video interaction
These requirements often demand months of engineering time and deep domain knowledge.
RealtimeKit is a complete toolkit for building real-time apps, including:
Cross-platform SDKs (iOS, Android, React Native, Flutter, Web)
UI components for faster frontend development
Server-side services with built-in support for recording, streaming, and AI integration
SFU, STUN, and TURN services from Cloudflare for seamless global media routing
It is purpose-built to make real-time development accessible to teams of any size — from solo indie developers to enterprise teams.
RealtimeKit is optimized for next-gen apps. Key features include:
Real-time audio and video capabilities
Low-latency (down to tens of milliseconds)
Integrated voice AI using partners like ElevenLabs
Real-time streaming to AI models with FastRTC + Hugging Face
This makes it ideal for:
AI-powered assistants with natural voice interaction
Live collaboration tools
E-learning platforms with real-time feedback
Cross-platform video meetings and events
One of the standout features is FastRTC, a Python library that enables real-time streaming to AI models via WebRTC. Now, thanks to Cloudflare’s partnership with Hugging Face, developers using FastRTC get free access to Cloudflare’s TURN servers, ensuring reliable connections across firewalls without additional setup.
As CEO Matthew Prince puts it:
“AI applications aren’t built on one tool — they’re built on a combination of many. That’s why we need strong infrastructure to connect them all seamlessly.”
Cloudflare Realtime is designed with accessibility in mind:
Pay-as-you-grow pricing
Scales to millions of concurrent users
Designed for global deployment on Cloudflare’s massive network
Minimal infrastructure investment required
For developers working on WebRTC, Cloudflare’s SFU and TURN services are now generally available, with added analytics and sync-broadcast support.
RealtimeKit can power a wide variety of real-time applications:
Video conferencing tools
Interactive online education platforms
Live streaming and co-watch apps
AI voice/chat interfaces
Custom real-time dashboards and collaboration tools
Cloudflare Realtime and RealtimeKit represent a bold move toward democratizing real-time app development. By offering a developer-first experience, deep AI integrations, and scalable infrastructure, Cloudflare is helping teams bring their creative ideas to life faster than ever.
If you're building something that requires voice, video, or real-time AI — it's time to give RealtimeKit a try.
