Looking for the most scalable websocket server?
MigratoryData is now used to stream real-time data to millions of end-users!

Push Real-Time Data to Any Web Browser

For old browsers without native WebSockets, data is pushed via techniques using a single persistent TCP connection, like WebSockets do. So, true data push is achieved for all browsers and it's pure JavaScript (no plug-in needed).

Industry's Most Scalable WebSocket Server

A single MigratoryData instance is able to handle up to 12 million concurrent users.

MigratoryData also scales horizontally using built-in load balancing to meet any growth in number of users.

Fault-Tolerant Guaranteed Delivery of Data

Multiple MigratoryData instances can be deployed as a fault-tolerant cluster to enable guaranteed delivery of data even in presence of sudden failures such as hardware failures and network disconnections.
