The API reference is clear, and the readability and docs design are decent. The quality of sample code provided is not great, and you often have to search for external examples. More tutorials would have been good, and more diverse (most of the existing ones focus on chat).” | 4.33 / 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 P: “Documentation is detailed, with many examples and tutorials from how to set up the parse server, connect clients to it, using different databases and hosting on different platforms”. O: “The documentation is extensive and at the same time offers higher level explanations for the more detailed sections.” W: “While the documentation offers a lot of information, examples and tutorials it could have been organized in a more clear manner and made more readable.” |
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 “Azure Portal allows you to configure and manage your Web PubSub deployment, e.g. creating a service instance, setting up endpoints and connections to the service, scaling connections, etc. All is pretty well explained, with plenty of tooltips and instructions in the UI. You can also monitor various stats such as the number of concurrent connections and how it evolves over time. There’s a live trace tool that makes it easy to capture and troubleshoot issues in realtime.” | 4 / 5 Ease of use / 5 Stats and reports / 5 Functionality / 5 P: “The dashboard is easy to set up. You get a good overview of the stored data, so you can easily manage the database. Features such as webhooks, jobs, logs, API console and push notifications are easily accessible. Lack of performance metrics is a downside.” O: “The dashboard has a clean and simple UI with management sections for the webhooks, jobs, logs, configs and API console. It also includes a browsing view.” W: “The dashboard UI is easy to understand and self-explanatory. On the downside there is no informative metrics available but on the upside there is a lot of functionality and configurations options and the API console where you can send HTTP and GraphQL queries is a nice feature.” |

API structure Reviewed by 3+ independent developers | 3.75 / 5 API consistency across SDKs / 5 Well structured / 5 Intuitive / 5 Simple / 5 “The API seems to be consistent across all the server SDKs, with few differences between languages. Parameters, methods, etc are pretty intuitively named. It’s not necessarily the most straightforward API to use, as it has many interfaces; plus, you will often find you need to do some data massaging.” | 4.50 / 5 API consistency across SDKs / 5 Well structured / 5 Intuitive / 5 Simple / 5 P: "The API across SDKs are mostly consistent, but support for Pub/sub is not available on all SDKs. Plenty of code examples of how to perform various operations”. O: “Most SDKs are well structured, simple and consistent. Although some are missing an API reference.” W: “The SDKs are intuitive and well structured for the most part. The SDKs could however have been more consistent.” |

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 | Limited There is support for pub/sub messaging using LiveQueries in the Javascript SDK, which uses WebSockets to subscribe & publish to channels. But LiveQueries is limited to the Javascript SDK. | |
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 One could keep track of online clients by using the LiveQuery triggers to know whether or not a client is connected. But there is no built functionality for this. | |
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 | ||
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 | Limited Connection recovery with continuity is possible only when reliable JSON WebSocket or Reliable Protobuf WebSocket subprotocols are used. Note that these reliable subprotocols are currently in preview, and some changes are expected in the future.
| |
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 | Limited Message ordering is possible only when reliable JSON WebSocket or Reliable Protobuf WebSocket subprotocols are used. Note that these reliable subprotocols are currently in preview, and some changes are expected in the future.
| |
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 Exactly-once delivery is possible only when reliable JSON WebSocket or Reliable Protobuf WebSocket subprotocols are used. Note that these reliable subprotocols are currently in preview, and some changes are expected in the future.
| Limited Idempodency enforcement exists, as an experimental feature that may not be appropriate for production. |
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 Only integrates with Azure Functions. Azure Web PubSub doesn’t have in-built support for other serverless platforms, such as AWS Lambda or Google Cloud Functions.
| Limited Cloud functions are used in parse server to run single-prupose piece of code. But is up to you to host the parse server, where the cloud functions are invoked from. The pricing model is different, since you are hosting the parse server yourself, you can invoke the cloud function for as many times as you like. Services like AWS Lambda charges you for the number of requests made and the duration of those requests. |
