Manage and distribute event-driven data streams to third party developers

Developers are demanding event-driven APIs beyond REST and Webhooks. Ably's platform makes it easy to deploy, manage, and distribute data streams to third party developers as event-driven APIs - so they can consume and integrate those data streams into their own apps. Offload the cost and heavy engineering lifting of creating self-service, performant event-driven API programs onto Ably.

CAP COMPLEXITY, NOT SCALE

Deploy your data streams to fully-managed realtime infrastructure


Ably decouples the complexity of distributing data from the simple operation of publishing event data as it happens. It ensures you have a fixed level of complexity and cost regardless of the number of downstream consumers of data. As data is generated from various sources, you need only publish those events once to the Ably network over an open protocol.

TAKE CONTROL

Tools for effective Realtime API management


You gain out-of-the-box data flow control through rich management dashboards, analytics on API usage, and access control tools (auth / API keys). You can control exactly who has access to data, specific aspects of data, volume of data, and even who pays for the data delivery costs (the bandwidth).

DATA HOW YOUR USERS WANT IT

End-to-end realtime data distribution


Built on Ably’s cloud network and realtime messaging fabric, developers can easily consume data at any scale, with any number of Pull and Push Subscription Protocols. Ably’s handles the heavy lifting of scale, performance, reliability, data integrity, protocol transformation (for example, MQTT or SSE) and push (e.g. serverless function invocation or Kafka delivery) all at sub-65ms global latencies.
