LiveKit

For developers looking to build voice, video, and physical AI agents, LiveKit offers a comprehensive open-source framework and developer platform, powering billions of calls in production for companies like OpenAI, which used LiveKit Cloud to build ChatGPT's Advanced Voice feature. LiveKit's platform allows for the building, testing, deploying, scaling, and observing of agents in production, with features like automatic turn detection and interruption handling, as well as simple and powerful APIs for quickly building voice agents. The platform supports integration with telephony, enabling voice agents to make or take phone calls, and offers a range of pre-built starter apps to bring agents to life through web or mobile applications. One notable limitation of LiveKit is its current lack of support for multi-language models in its turn detection feature, which may hinder its effectiveness in certain global applications. Despite this, LiveKit's cloud platform provides a global real-time infrastructure for deploying and scaling agents, with full-stack observability for every agent session, making it an attractive option for developers looking to build and deploy sophisticated AI agents. With its open-source framework and cloud platform, LiveKit provides a robust foundation for building a wide range of AI-powered applications, from voice assistants to robotics, and its ease of use and scalability make it a popular choice among developers, with over 11.5K agents and 19.9K users on its platform.
