Devs love working with LiveKit, but running a real-time video network at scale in prod is hard. Most teams would rather focus on finding product-market fit. So we built a global SFU mesh, where users connect to edge nodes, and most data travels over backbone connections.

The industry-standard participant-minute pricing model for live audio/video is cost-prohibitive for certain use cases, making entire classes of apps economically unviable So we designed a cost-plus pricing model where you only pay for the bandwidth and compute your app uses
