Realtime features
Pub/Sub messaging Pub/Sub is a design pattern that lets any number of publishers (producers) push messages to channels (also known as topics). Multiple subscribers (consumers) can subscribe to a channel to consume published messages. Explore Ably's pub/sub messaging implementation
Message queues A message queue is a form of asynchronous service-to-service communication. Messages are stored on a queue until they are processed. Note that each message is only consumed by one subscriber (consumer). Explore Ably's message queues implementation
Presence Presence enables you to track the online and offline status of devices and end-users in real time and to store their state. Essential for chat apps and multiplayer games. Explore Ably's presence implementation		Limited Presence is only available for Sendbird Chat, but it's not supported by other products like Sendbird Desk and Sendbird Calls.
Message history Message history provides a means to retrieve previously published messages. For this to be possible, message data must be stored (persisted) somewhere. Explore Ably's message history implementation	Limited The --mem-queue-size can be increased and messages can be written to disk; however, this is mainly an in-memory messaging platform.
Connection state recovery (stream resume) In the case of unreliable network conditions, clients may suddenly disconnect.Connection state recovery ensures that when they reconnect, the data stream resumes exactly where it left off. Explore Ably' s connection state recovery implementation
Guaranteed message ordering Ordering ensures that messages are delivered to consumers in the same order that producers publish them. Explore Ably' s guaranteed message ordering implementation
Exactly-once semantics Exactly-once is a system-wide data integrity guarantee that ensures each message is delivered to consumers exactly-once. Explore Ably' s idempotent publishing implementation	Limited The only guarantee is that messages will be delivered at least once. However, it is possible to obtain idempotency with some client configuration.
Message delta compression Message delta compression enables you to only send the changes from the previous message to subscribers each time there’s an update, instead of the entire message. Useful for use cases where there is a significant degree of similarity between successive messages. Explore Ably' s message delta compression implementation
Native push notifications Native push notifications can be used to deliver messages even when clients are offline. Useful for geolocation updates or news alerts. Explore Ably's push notifications implementation
Webhooks Webhooks provide a mechanism to get messages and other types of events (such as clients entering or leaving channels) pushed to your servers over HTTP. Explore Ably's webhooks implementation
Serverless functions A serverless function is essentially an isolated, single-purpose piece of code that is only executed when it’ triggered by an event. For example, you can use serverless functions to send a welcome message to clients when they become present on chat channels. Note that serverless functions are usually fully managed by cloud vendors. Explore Ably's serverless functions implementation

Global and reliable edge service
Edge messaging network with latency-based routing Latency-based routing ensures that clients are always routed to the nearest datacenter and point of presence. Explore Ably's routing mechanism that mitigates network and DNS issues
Multi-region data replication (message durability) Multi-region data replication (storage) protects against single points of failure and ensures message data durability. Learn how Ably ensures message durability	Limited It is possible to set up redundant nsqd pairs that will receive the same portion of messages.
Uptime SLAs Here’s what the most common SLAs amount to in terms of downtime over a calendar year: 99.999% SLA = 5m 15s downtime per year 99.99% SLA = 52m 35s downtime per year 99.95% SLA = 4h 22m 58s downtime per year 99.9% SLA = 8h 45m 56s downtime per year 99% SLA = 3d 15h 39m 29s downtime per year Source: https://uptime.is/	N/A	Unknown

Security
API key authentication The simplest way to authenticate. Involves using private API keys that you can usually create and edit via a dashboard. Recommended to be used server-side, as private API keys shouldn’t be shared with untrusted parties. Explore Ably's implementation of API key authentication	N/A
Token-based authentication Which popular token-based authentication mechanisms do NSQ and Sendbird support? Note that token-based authentication is usually the recommended strategy on the client-side as it provides more fine-grained access control and limits the risk of credentials being compromised.
