Global real-time video and voice infrastructure with SDK breadth and low-latency network
Agora is the most globally distributed real-time video/voice provider in 2026. Their proprietary SDN (Software-Defined Network) routes traffic across 200+ data centers and consistently delivers the lowest measured latency on international video calls. SDK breadth is the largest in category — gaming engines (Unity, Unreal), every mobile platform, web, even hardware integrations. Trade-off: pricing requires understanding the per-minute model across video/voice/recording dimensions, and the developer experience leans toward enterprise (more wrapper code than LiveKit or Daily).
Cross-region latency is the win. Agora wins on the SDN.
For a global B2B app with users in 40 countries, Agora SDN consistently delivered lower latency than LiveKit Cloud and Twilio Video. Measurable on every continent.
Unity SDK is the most mature in the category.
Built voice chat for a Unity multiplayer game. Agora SDK shipped, configured, and just worked. Alternatives needed wrapping or had Unity-specific gaps.
Pricing model takes a week to model accurately. Watch the dimensions.
Per-min pricing varies by video resolution tier, audio quality, recording usage, regions. We spent a week building a cost model. Eventually fine but the learning curve is real.
