Stream provides infrastructure APIs and SDKs that community builders use to add professional-grade chat messaging, video calling, and activity feeds to their custom community platforms. Community developers can integrate features like member chat, community livestreams, and social feeds without building complex real-time infrastructure from scratch. The platform is designed for technical teams building custom community experiences rather than no-code community managers.
