Documentation Reviewed by 3+ independent developers Explore Ably's documentation for our pub/sub messaging platform | 3.83 / 5 Getting started guides / 5 Information architecture and developer journey / 5 API reference documentation / 5 Readability, design and navigation / 5 Quality of code / 5 Breadth and quality of tutorials / 5 “The navigation and information architecture are well thought out, and the documentation is largely clear and easy to comprehend. The getting started guide is good, but it lacks some screenshots, which would have broken down the monotony of walls of text. The tutorials are essentially detailed step-by-step guidances that are easy to follow. Sadly they do not cover programmable steps and don’t provide any code snippets - they focus entirely on performing actions from the AWS console”. | 2.50 / 5 Getting started guides / 5 Information architecture and developer journey / 5 API reference documentation / 5 Readability, design and navigation / 5 Quality of code / 5 Breadth and quality of tutorials / 5 “The documentation is overall disappointing. The API reference, some comprehensive FAQs, and some decent writing for SDK-specific guides are noteworthy highlights. However, the rest is not great. There is no navigation sidebar; all the various sections of the docs are individual articles that are listed on a menu page. Furthermore, the sections are not organized in a logical manner; it’s unclear where to start, and often hard to understand how the topics connect. There are only a few GitHub tutorials, with some brief steps, but certainly not enough details. Overall, you get the feeling the documentation fails to deliver relevant bits of information, and getting started with Kaazing was far from easy.” |
Dashboard or dev console Reviewed by 3+ independent developers Sign up for free and explore Ably's pub/sub messaging platform | 4 / 5 Ease of use / 5 Stats and reports / 5 Functionality / 5 “The EventBridge console provides all the functionality you need for managing event-driven pipelines, rules, event buses, and targets. Additionally, it supports native integrations to ingest events from a few external, non-AWS event sources. This includes some popular SaaS platforms such as ZenDesk, Datadog, Segment, and more. The console is tricky to use for new starters, and you constantly have to switch to other AWS services, such as Cloudwatch (for stats and reports).” | 1 / 5 Ease of use / 5 Stats and reports / 5 Functionality / 5 "Kaazing WebSocket Gateway does not provide a developer console or dashboard." |

API structure Reviewed by 3+ independent developers | 4.25 / 5 API consistency across SDKs / 5 Well structured / 5 Intuitive / 5 Simple / 5 “EventBridge APIs are available as part of the AWS SDKs. They are largely consistent across programming languages, straightforward, and relatively easy to use. The API reference is detailed and includes plenty of examples. In any case, you’re probably better off interacting with EventBridge from the AWS console, since the product seems to be designed to be used this way primarily.” | 4 / 5 API consistency across SDKs / 5 Well structured / 5 Intuitive / 5 Simple / 5 “Kaazing offers SDKs in several different programming languages, and for different operating systems. The naming conventions make the APIs reasonably intuitive and simple to understand, and the extensive API references help a lot. The APIs are mostly consistent at a class level, which makes sense, since the WebSocket ones are basically modeled around the standard WebSocket API. Note that the client SDKs also provide additional protocol capabilities, such as AMQP and JMS, which is quite useful.” |

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 | Limited Amazon EventBridge integrates with Amazon SQS (Simple Queue Service) in order to provide message queues. | |
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 You can configure Kaazing WebSocket Gateway to hold recent messages for a topic in a last value cache. However, you are required to use a JMS-compliant message broker, such as RabbitMQ. | |
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 EventBridge only integrates with AWS Lambda Functions, but does not support other serverless platforms, such as Azure Functions or Google Cloud Functions. | |

Community Reviewed by 3+ independent developers Explore Ably's community support channel for our pub/sub messaging platform | 2.50 / 5 Presence on multiple channels / 5 Size and activity / 5 “Unlike other AWS communities, the EventBridge community seems to be quite small. There are some discussions happening on StackOverflow, but on other communication channels, such as Gitter, there’s nothing happening. There are about a dozen public projects posted on GitHub, showing, for example, how to use EventBridge with Lambdas to send alerts to Slack”. | 1.50 / 5 Presence on multiple channels / 5 Size and activity / 5 “Kaazing is present on a few platforms, such as StackOverflow, Gitter, and GitHub. However, all discussions and GitHub issues seem to date back from 2018. All in all, there’s nothing to indicate Kaazing has an active and thriving community. There only seem to be a few projects made by the community, and almost no community-made content (blogs, tutorials).” |
