Lightstreamer is described as 'server for delivering real-time messages to browser-based and mobile applications, using WebSockets and HTTP. Features include dynamic throttling, bandwidth and frequency control, delta delivery, and total control over security and the quality of service' and is an app in the Development category. There are four alternatives to Lightstreamer for a variety of platforms, including Linux, Online / Web-based, Windows, Mac and Node.JS. The best alternative is Socket.io, which is both free and Open Source. Other great apps like Lightstreamer are Pusher (Paid), Ably (Freemium) and Atmosphere Framework (Free, Open Source).
Ably’s APIs provide developers with the infrastructure to power realtime functionality at any scale. Instead of building and operating infrastructure, engineers can focus on shipping the features and functionality that matter to their customers.
