getstream.io

getstream.io is a backend-as-a-service platform that provides APIs and SDKs for adding real-time chat, video calling, activity feeds, and content moderation to applications. Instead of building these features from scratch, developers can integrate them with a few lines of code. The platform handles infrastructure scaling, reliability, and compliance so teams can focus on their product logic. It supports multiple use cases from social apps to healthcare, dating, gaming, and live shopping.

What makes getstream.io stand out is its unified approach: one platform offering chat, video, feeds, and moderation on shared infrastructure. It claims sub-9ms API latency, 99.999% uptime, and support for millions of concurrent users. The SDKs come in 10+ languages and frameworks, with typed APIs and clear documentation. Recently, the company released an open-source Vision Agents SDK for building multi-modal AI applications. getstream.io also includes AI-powered moderation to automatically flag inappropriate content in chat and feeds.

The platform is designed for developers who need to ship real-time features quickly without managing infrastructure. It's best suited for product teams at startups and enterprises building social networks, marketplaces, on-demand services, or any app requiring real-time communication. Use cases include adding chat to a delivery app, building a social feed for a fitness community, or integrating video calls for telehealth. With a free tier that doesn't require a credit card, it's easy to evaluate.
