It's easily navigable, and the written and video tutorials are in-depth, but there could be more of them. The different products that make up the Sendbird platform are clearly separated (e.g. Chat, Calls, UIKit, etc) before introducing the SDKs and API. This gives users an overview of the products before diving into its documentation. Each product has API reference documentation. The key functionalities of that product are listed out for easy access. Generally, in terms of comprehensiveness, readability, navigation, ease of use, and code quality, the documentation is very solid. | 4.83 / 5 Getting started guides5 / 5 Information architecture and developer journey4 / 5 API reference documentation5 / 5 Readability, design and navigation5 / 5 Quality of code5 / 5 Breadth and quality of tutorials5 / 5 The documentation is quite comprehensive and well detailed, with easy access to code samples while you read through it. There are quickstart tutorials for all the products using different SDKs. However, I feel some developers may get lost while trying to find references or while trying to navigate the various pages, especially around the API reference. |
Dashboard or dev console Reviewed by 3+ independent developers Sign up for free and explore Ably's pub/sub messaging platform | 5 / 5 Ease of use5 / 5 Stats and reports5 / 5 Functionality5 / 5 ![]() The dashboard allows you to create and manage applications. It also enables you to see all the stats and reports you need about monthly and daily active users, and peak concurrent connections. It also enables you to create and manage chat channels and make calls, making it easy to test. It has a slick design and is quite intuitive to use, and it’s divided into five features; overview, users, settings, calls, chat. It also has moderation tools that you can use to protect your conversations directly from your dashboard. | 4.33 / 5 Ease of use4 / 5 Stats and reports4 / 5 Functionality5 / 5 ![]() The dev console allows you to manage and configure all things Twilio. This includes SMS, Chat, Notify, Sync, Voice, Video, etc. The stats and reports gives its users a general overview of what goes on with their account. This includes API accessed, cost, exact time of access. Besides the general overview, I like the fact that every product has its page where users can view a better breakdown of the activities. I also like that activities are being viewed in monthly ranges. This means you get a detailed report for activities in a month. This way, the report isn’t clumsy or cumbersome. |

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 | ||

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 | ||
Token-based authentication Which popular token-based authentication mechanisms do Sendbird and Twilio 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.
