Stream is a developer platform that provides hosted APIs and SDKs for building chat messaging and activity feed features into applications. It handles the backend infrastructure so engineering teams can add real-time communication without building it from scratch.
Stream offers two main products: Chat, which supports channels, threads, reactions, and moderation tools, and Feeds, which powers social-style activity streams. The platform supports SDKs for iOS, Android, React, Flutter, and other popular frameworks. Stream is used by companies ranging from startups to large enterprises, and it offers a free tier for smaller projects.
