First of all, it’s all over the place in terms of format: from GitHub READMEs to the most basic of HTML pages to PDFs. There’s even a slide deck. Resources are seldom cross-linked, which makes the docs hard to follow. The entire design of the website is from the last century. It’s aesthetically hideous, and the navigation experience is underwhelming. The only positive things are the API reference, which is quite comprehensive, and the GitHub tutorials, which are explained well.“ | 3.50 / 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 “Push Technology documentation for its Diffusion product consists of several components. First, we have a quick start guide, which is pretty decent. It’s structured to provide step-by-step guidance on how to set up Diffusion and use the APIs and the SDKs. The screen is split so that you can look at documentation and code snippets in parallel - a nice touch. Then, there’s an online manual, which is significantly more detailed, with code snippets throughout. Unfortunately, there aren’t any details in the guide about the quality of service or how to architect for scalability. There’s a detailed API reference for each SDK and comprehensive release notes. The design could be improved, as it’s a bit dry, and so could the navigation experience - some links return 404, and the various sections of the documentation aren’t cross-linked. There are just a few demos available, with no source code and only several tutorials.“ |
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 “Lightstreamer provides a monitoring dashboard that shows various realtime metrics and stats related to the server-side, such as connections, sessions, or throughput. The event log is pretty useful, showing successful operations/events, warnings, and errors. It’s intuitive and straightforward to use, although the UI is dull and ugly. Unfortunately, there’s no dev console or portal with more extensive functionality to allow you to create and manage resources.“ | 4.67 / 5 Ease of use / 5 Stats and reports / 5 Functionality / 5 “The Service Dashboard is feature-rich, and it allows you to easily create, manage, and remove resources, configure settings, and view detailed stats, such as the number of messages, the CPU load, or the topic count. There’s also a nice section in the Dashboard that allows you to test your pipeline. The user experience is mostly intuitive, and the functionality is explained well (there are many tooltips throughout). However, the UI design could perhaps benefit from a refresh, as it’s a bit outdated.“ |

API structure Reviewed by 3+ independent developers | 3.25 / 5 API consistency across SDKs / 5 Well structured / 5 Intuitive / 5 Simple / 5 “Lightstreamer provides APIs covering many languages, operating systems, and development platforms, such as Java, .NET, JavaScript, or iOS. There’s a separate API reference page for each SDK - a highlight in otherwise mediocre documentation. The references are pretty detailed, and the APIs are fairly well structured and consistent across SDKs. But they aren’t simple, and it takes some time to wrap your head around them. They perhaps don’t have the most intuitive naming conventions, and the code samples included are not as clear as they could be“. | 3.25 / 5 API consistency across SDKs / 5 Well structured / 5 Intuitive / 5 Simple / 5 “Diffusion APIs are consistent across SDKs in the sense that operations are performed in the same order. However, the APIs are quite complex - there are tens of classes and methods, with some different naming conventions across some of the SDKs, such as JavaScript, Java, or C, which is counter-intuitive. The API references are structured and presented differently, which is not great; at least they are detailed and thorough. There are examples for all SDKs on GitHub, which is 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 Queues are supported only via the Lightstreamer JMS Extender, which connects to any third-party JMS server and makes JMS (Java Message Service) available on the Web. Any HTML page running inside a web browser and any Node.js application instantly become JMS clients, able to publish and subscribe on JMS topics and 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 | ||
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 Push Technology operates a recovery buffer of sent messages but if a message has been lost or is no longer in the recovery buffer the server will abort the reconnection. | |
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 | ||

Pricing & Support | ||
---|---|---|
Free package What do the free packages offered by Lightstreamer and Push Technology consist of? Explore Ably's free package for our pub/sub messaging platform | Lightstreamer’s free package (the community edition) provides a license for one server and unlimited clients. However, the message rate is throttled at one message per second, and some features are unavailable (such as clustering or TLS support). | The free package includes 3 million monthly messages, 100 peak connections, unlimited topics, access to all major features and adapters, and basic support. |
Pricing model How are the Lightstreamer and Push Technology pricing models calculated? Explore Ably's pricing model for our pub/sub messaging platform | Lightstreamer has a complex and confusing pricing model. First, you must choose between the community edition (free) and the enterprise edition (paid). When you select enterprise, you must then opt between the Enterprise or the Enterprise Ultimate package (the latter includes all client APIs, superior message rates, and all features). On top of this, you must choose a licensing scheme, of which there are six options in total. Some examples: Perpetual Upfront per Server License, Monthly Pay-as-you-go Per Core-Hour License, Annual Upfront per Client Licence. Once you choose a licensing scheme, you must also choose a license type, such as Demo, Evaluation, Production, or Hot-Standby. There’s no transparency regarding cost estimation or concrete numbers (at least not on their website). | The basic pricing for the Business package starts at $49 per month. In addition, there are charges for the number of messages - $ 0.99 per million messages and for the number of connections - $ 0.01 per connection. It’s unclear how pricing is calculated for the Enterprise package. |
Enterprise package What benefits do the Lightstreamer and Push Technology enterprise packages offer? Explore Ably's enterprise package for our pub/sub messaging platform | Lightstreamer has an Enterprise Ultimate package that includes all client APIs (different programming languages), provides unlimited messages without throttling, and grants access to all features. | The Enterprise package benefits include enterprise scale and performance, cross-region replication, configurable cluster size, bespoke performance tuning, bespoke packages for all sizes. |
