Platform

A rock-solid platform with all the features you need to build scalable realtime apps and services

Ably Realtime Core

Ably's global distributed realtime data delivery platform provides a rock-solid foundation to deliver core realtime functionality such as pub/sub, presence, device awareness, history, connection state recovery, authentication and encryption. Ably's additional services are delivered as part of the core platform.

Smart Notifications

Ably’s Smart Notifications offers a less intrusive and more effective way to notify your users with native iOS, Android and browser notifications. Instead of delivering “dumb” push notifications to your users when you wish to get their attention, Ably allows you to deliver messages based on a user’s connection state, their active device and their current context within your application.

Protocol Adaptors

The Ably platform ensures interoperability between clients using our native Ably realtime protocol, and clients using other realtime or queueing protocols, including some of our competitors. We believe customers should choose the right protocol for the job, and migrate to Ably with ease.

Reactor

Reactor Events runs code on your servers or by invoking server-less functions for each message in real time.

Reactor Queues provide a scalable way to consume realtime data from your servers.

Reactor Firehose streams your data into 3rd party systems such as Kinesis or Kafka.

Exchange

The Ably Exchange is still being built so we're not quite ready to tell you about it. Watch this space, we'll be making announcements as we get closer to our launch date.

    See how
  • Presence and device awareness

    Subscribe to events when devices or users enter, leave or update their state on channels.

    See how
  • Message history

    Realtime data persisted into our database can be retrieved at a later time by devices or servers.

    See how

    Connection state recovery

    With Ably, loss of connectivity does not need to result in data loss. We provide message continuity to your users when their devices become disconnected for up to two minutes.

  • Unique to Ably

    Pusher & PubNub support

    We support some of our competitors' protocols too which simplifies migrating over to Ably.

    See how
  • Token based access control

    You can configure which realtime data and features your users can access using secure tokens issued and signed by your own servers. You maintain complete control.

    See how
  • End-to-end encryption

    If you consider your data to be sensitive, then our libraries offer symmetric 256-bit AES encryption ensuring no one, including ourselves, can inspect your data payloads.

  • Unique to Ably

    Smart mobile and browser push notifications

    Use our smart browser and push notifications to get your users' attention when they're not already engaged with your app.

  • Unique to Ably

    Guaranteed delivery & ordering

    When the integrity and ordering of your data matters, our quality of service and reliable message ordering guarantee lets you focus on building your app.

  • Unique to Ably

    Binary protocol

    Our client libraries use an efficient binary protocol that reduces bandwidth and improves encoding and transmission performance.

    See how
  • Unique to Ably

    Message queues

    Process, transform and respond to realtime data as it happens. Our message queues allow you to do this the right way from your own worker servers.

    See how
  • Enterprise only

    Firehose

    Stream your realtime data published within the Ably platform directly to another streaming or queueing service such as Amazon Kinesis or Apache Storm.

    See how
  • Coming soon

    Server-less functions

    Allow your server-less functions, such as Amazon Lambda, to be invoked following channel lifecycle events (such as channel creation), presence events (such as members entering or leaving) or messages being published.

    See how
  • Multiplexed Websockets

    Our client libraries primarily use an efficient multiplexed Websocket connection to subscribe and publish messages on any number of channels.

    See how
  • Realtime analytics

    Use our account dashboards or REST APIs to get access to your account analytics in real time.

    See how
  • Exchange in stealth

    We're really excited about the Ably Exchange, but we're not quite ready to tell the world about it. Watch this space.

Platform benefits


Performance

Limitless capacity from our global high-performance infrastructure

  • Low latency

  • True server mesh

    • There is no single point of congestion
    • Load is dynamically assigned and reassigned across the network of servers in real time
    • Service auto-heals and routes around networking or server failures
  • Unlimited scale

    • Built primarily on Amazon EC2 infrastructure, Ably can scale without limits to meet demand
    • Each datacenter scales independently to meet demand in that region
    • At our peak, we have achieved a rate in excess of 4,000,000 messages per second! Twitter's record of 327,000 per second was set during the 2012 US elections
  • Intelligent routing

    • Messages are always delivered within our server mesh using the shortest route
    • Our routing algorithms ensure performance of a single region is never effected by another region
    • Example: a message published in Europe is broadcasted immediately by the same datacenter to European clients whilst concurrently relaying the message to other regions

Reliability

Always operational, with no single point of failure


Integration

Clearly documented APIs and libraries, and all the support you need


Security

Solid protection for you, your users and their data

  • Authentication

    • Token-based authentication ensures private keys remain private, and compromised tokens would have limited value because of their expiration
    • Support for basic authentication over SSL/TLS connections for authentication convenience
  • DoS protection

    • Benefit from our scale and ability to defend against DoS attacks meaning attacks have no effect on your servers
    • We can deny detect and deny invalid connection attempts at the edge of our network ensuring our core infrastructure is unaffected
  • Privilege-based

  • Encryption

    • SSL/TLS encryption available for all packages
    • 256-bit AES encryption available using your private key, meaning no one, even Ably, can read your messages without your private key
    • All REST based communication is secured by SSL/TLS ensuring server-to-server communication is always secure

Connectivity

Optimized connections for any internet-enabled device on earth

  • Any transport

    • WebSockets are our preferred transport because of their portability and performance
    • Failing that, we fall back to XHR Streaming, HTTP Polling, and even JSONP where necessary.
    • Ably simultaneously opens connections on multiple transports and upgrades or downgrades as necessary, meaning clients connect quickly regardless of the transport available
  • Mobile optimized

    • Our client libraries detect changing network conditions and select transports to best suit the current connection.
    • Library support for iOS, Android, Cordova / PhoneGap, Xamarin with more coming soon, see our mobile browser support.
    • Ably retains connection state on our servers ensuring clients that are disconnected will not lose data whilst disconnected.
  • Any device

    • Client libraries for almost every internet-enabled platform on earth
    • Connections are optimized based on the device's capabilities
    • Support for devices ranging from PCs and servers, to tablets, mobiles and even game consoles
  • Legacy browsers

    • Support for legacy browsers that don't support WebSockets or even XHR
    • Our library provides workarounds for CORS and other browser and firewall security restrictions
