APIs, SDKs, and UI Kits developers love

Sendbird's APIs for chat, voice, video, AI chatbots, SMS, WhatsApp, KakaoTalk, and in-app notifications are highly-abstracted and available through SDKs and UI Kits that save developers' time and headaches. We take care of a ton of operational complexity under the hood, so you can power rich communication experiences without worrying about building features, edge cases, reliability, or scale. Plus we offer easy-to-use software interfaces for other teams to take advantage of your integrations.
