Ably is a realtime experience and messaging infrastructure platform that provides the building blocks for adding live, scalable features — like chat, presence, live updates, notifications and data broadcasting — to applications. Building reliable realtime functionality is genuinely hard: it requires maintaining persistent connections, handling scale, guaranteeing message delivery and ordering, and managing the complexities of distributed systems. Ably abstracts all of this into dependable infrastructure delivered through simple APIs, so developers can ship realtime features without building and operating the hard underlying systems themselves.

The platform offers pub/sub messaging, presence (knowing who's online), message history, and guaranteed delivery and ordering, all built to scale to millions of connections with high reliability and low latency across a global network. Developers use Ably to power experiences like live chat, collaborative apps, live sports and finance updates, multiplayer features, IoT data streaming, and realtime notifications — anywhere data needs to move instantly and reliably between servers and many clients. With SDKs across platforms and a focus on dependability (including strong delivery guarantees and uptime), it provides the trustworthy realtime backbone that these features require.

Ably is used by companies and developers that need to add realtime functionality to their products and want robust, scalable infrastructure rather than building and maintaining it in-house. By handling the difficult engineering of realtime messaging at scale — connections, delivery, ordering, presence and global distribution — it lets teams focus on their application features and ship realtime experiences confidently. Its emphasis on reliability and scale makes it suitable for serious, production use where realtime data matters. As users increasingly expect live, collaborative and instantly-updating experiences, dependable realtime infrastructure is increasingly important. For developers and companies that want to build live, scalable realtime features without operating the underlying systems, Ably offers a powerful, reliable and well-regarded solution.
