The Ably API Streamer makes it easy and cost-effective for developers to publish Realtime APIs (also known as event-driven APIs or streaming APIs) at scale. Built on Ably’s global Data Stream Network, this layer of realtime API management tools and features makes it simple to deploy, manage, and distribute data streams as Realtime APIs.

Effortlessly expose your realtime APIs

  • Deploy

    Fully-managed serverless infrastructure so you can quickly deploy realtime APIs. We support integration with cloud, hybrid, or on-prem environments for seamless integration, whatever your architecture.
  • Manage

    With the API Streamer there’s no need to build in-house tooling to manage your realtime APIs. Our management dashboard provides all the tools you’d expect: registration, permission management, analytics, rate limiting, security, and more.
  • Distribute

    API Streamer is built on Ably’s battle-tested Data Stream Network, enabling end-to-end streaming from data source to end-user device in milliseconds. It's infinitely scalable - you only pay for the capacity you use.

Universal interoperability = reusable realtime API endpoints

Developers can deploy a stream once, using whichever protocol they wish, and create re-usable API endpoints. API Streamer’s adapter function transforms source protocol to client destination protocol for unlimited numbers of customers to integrate with using the protocols and platforms of their choice.

Who’s using Ably?

Hundreds of companies trust Ably to deliver their realtime data.

Multiple Pull Subscription Protocols reduce friction for in-bound stream subscribers

Ably supports multiple protocols such as MQTT, SSE, or Ably’s native WebSocket-based protocol for subscribing to streams. We call these Pull Subscription Protocols because clients initiate the connection to Ably and request (or ‘pull’) a stream of data from the Ably network. This reduces integration work for you as your clients can easily connect to Ably’s network and subscribe to specific streams on-demand using the most appropriate protocol. Plus you future proof your tech stack as Ably will continue to support emerging protocols.

Multiple Push Subscription Protocols to help subscribers consume your streams at scale

When the volume of messages or number of channels is high, complexity for subscribers increases and it becomes impractical to consume data on-demand. Using Push Subscription Protocols subscribers can push streams into third party streaming or queueing services like Kafka, AMQP (RabbitMQ), Amazon SQS/Kinesis, or trigger serverless functions. This helps them easily scale consumption of your data streams, reducing engineering work for both them and you.

A uniquely end-to-end solution

Ably API Streamer isn’t just a platform for B2B server-to-server communication. The platform can stream data direct from its source — such as an IoT device — right through to wherever it needs to go, even as far as an end-user’s mobile app. No other platform supports the complete data supply chain in this way.

Designed with developers in mind

Whether you’re producing data, or consuming data, Ably offers APIs that developers love. They can work in any language and platform they want as we offer all the popular SDKs. If developers prefer open protocols, they can choose one of many protocols we support, and an encoding like JSON or binary MsgPack of their choosing.  And if developers consuming data from the API Streamer want data pushed to their services, we support every popular cloud, queuing, streaming and serverless environment.

Transform and filter your data

Consumers may not need all the data you publish, or indeed want the data in the same format you’re publishing it. Our soon-to-be-activated transformation and filtering capabilities will let you publish custom streams for your customers with transformations and filters applied. You can even allow consumers to filter the data they need, in the formats they want, with no involvement from you.

Efficient data delta streaming

By generating binary data deltas, API Streamer optimizes the bandwidth requirements for subscribers by sending changes instead of the entire payload for each message. You benefit from lower data costs and your customers gain a better user experience thanks to faster stream delivery. Note that compression and savings vary based on the significance of deltas and message content.

Depend on super-low latencies

Our proximity to your subscribers, with 16 datacenters globally, means Ably API Streamer can guarantee class-leading performance with the lowest latency service available. We currently deliver global round-trip median latencies of less than 65ms

Take control of your streaming APIs

We give you all the tools you need to manage your APIs. Your producer dashboard gives you complete control over who has access to your data products, and full analytics detailing what data is produced and distributed. You control how much is distributed and who’s paying for the data distribution and bandwidth costs.

Keep your information safe and secure

We want to keep your APIs and data safe and secure from attack. Denial of Service protection and mitigation is baked into the service. And end-to-end encryption is available in addition to numerous authentication and authorization schemes, including token based and JWT authentication with fine grained access controls.
