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
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 maximum message retention duration is 13 months. In October 2020, this was one of three key changes Twilio made in the way it stores message records: 1. Message log history will only be available from the last 13 months via Twilio Console and the Messages API Resource. Messages logs older than 13 months will still be accessible via the Bulk Export API, or the Bulk Export Message Log Archives in Console. 2. All Media Objects (e.g. MMS and WhatsApp message file attachments - pictures, audio, etc.) from Messages older than 13 months will be permanently deleted. 3. Deleting a Message log will also automatically remove any Media objects associated with that message. This applies to all Twilio products.
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
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	Limited Can only trigger Cloud Functions for Firebase. Does not support other serverless platforms, such as AWS Lambda or Azure Functions.

Free package What do the free packages offered by Firebase and Twilio consist of? Explore Ably's free package for our pub/sub messaging platform	The Spark plan includes several products from the Firebase suite that are entirely free to use, such as cloud messaging (FCM) or in-app messaging. The Spark plan also allows for free usage of most of the other products, up to certain limits. Some examples: first 125k/month Cloud Functions invocations free, 10 GB of free storage (hosting), and 1 GiB of free storage in Cloud Firestore.	Not bad On Twilio Sync, your first 200 endpoint-hours for each month are free: “Endpoints are unique devices or browser tabs and are counted once for each wall-clock hour during which they interact with Sync. Each unique endpoint will incur charges of at most $0.01 per calendar day.” Users also get free access to their first 10,000 actions each month: “Actions are defined as incoming requests from your application that read and write data. Resulting webhooks, updates to connected endpoints, and storage are included in the cost of an action.”
Pricing model How are the Firebase and Twilio pricing models calculated? Explore Ably's pricing model for our pub/sub messaging platform	Firebase offers two pricing plans: the Spark plan (free) and the Blaze plan (pay as you go), which is recommended for building apps at scale. Most Firebase products are entirely free to use for both plans, with hard limits on some products for the Spark plan (and some missing features, too). The Blaze plan includes the free usage from the Spark plan and allows access to all Firebase features and products. On top of that, pricing is calculated monthly based on a multitude of factors, such as message ingestion & delivery, document read, write, delete operations, data storage, hosting, or function invocations. For example, Cloud Firestore storage is calculated at $0.18/GiB, and hosting is calculated at $0.026/GB.	Pricing varies on what service you intend to use. Specifically for Twilio Sync, the pay-as-you-go model is employed and pricing depends on the endpoint-hour. Here is the breakdown: Accessing 201 and 12,000 endpoint-hours costs $0.00250/endpoint-hour Once the 12,000 endpoint-hours threshold is crossed, users begin to pay a lesser amount. Between 12,001 and 72,000 users pay $0.00200/endpoint-hour Find out more about Twilio Sync pricing
