Reactor
Real-time video development platform built by former Apple engineers, featuring sub-50ms streaming latency
Visit Website ↗What is Reactor
Reactor is a real-time video infrastructure platform for developers, co-founded by former Apple Vision Pro technical leads Alberto Taiuti and Bryce Schmidtchen in August 2025. After securing $59 million in funding led by Lightspeed Venture Partners in mid-2026, Reactor emerged from stealth mode. Its mission is to make real-time world models accessible to all developers, abstracting away the complexity of deploying and running these systems at scale.
Key Features and Use Cases
Reactor boasts 'the fastest inference anywhere,' offering sub-50ms streaming latency and integrating multiple world models into a single API. It provides a unified SDK and API, enabling developers to build real-time interactive applications with just a few lines of code, without managing the intricacies of large-scale deployments. Pricing is based on usage, with costs varying by model type. As an infrastructure platform rather than a consumer-facing tool, Reactor is suited for applications requiring real-time image streaming, such as interactive games and virtual worlds, real-time AI video filters, live interactive effects, and research and product teams needing low-latency world model inference.

Editor's Note
Editor's note: While many tools focus on video quality, Reactor shifts the battlefield to 'real-time' and 'infrastructure.' For Taiwanese developers looking to build real-time interactive AI applications, Reactor represents a new option for underlying computational power and latency, but it's essential to note that it's engineering-oriented and not plug-and-play.
