When Milliseconds Matter

The world's most scalable WebSocket messaging server


MigratoryData is a distributed WebSocket messaging server. With the ability to handle up to 10 million concurrent clients from a single commodity server, MigratoryData makes it cost-effective to stream real-time messages to and from millions of end-users — across web, mobile, and IoT devices.

Messaging to any client

Build real-time features for your web, mobile, and IoT applications using our WebSockets-based publish/subscribe messaging API with libraries for the most popular languages and platforms including iOS, Android, JavaScript, Java, C#, Objective-C, C++, Node.js, Python, PHP, Dart, MicroPython, and more.

Messaging at any scale

MigratoryData can be deployed on multiple servers as a cluster, scaling horizontally by simply adding nodes to the cluster. But more importantly, MigratoryData scales vertically up to 10 million concurrent users on a single server. This makes it up to 10x more scalable than leading messaging products.

Guaranteed messaging

MigratoryData achieves ultra-high scalability without sacrificing integrity. We implement active/active clustering, replication, and distributed in-memory caching to ensure message ordering and message delivery guarantees despite hardware failures and network disconnections.

From Our Clients

“MigratoryData technology is a key part of the software we have developed to help our clients lower their support, hardware, and software costs, eventually allowing them to replace their older thick-client terminals with a browser-based, thin-client application with all of the same capabilities but none of the system overhead.“ — Chris Boruff, President of Advisor Software, Morningstar

“MigratoryData has allowed Heritage to take our real-time auction bidding system to the next level; providing more scalability, reliability, flexibility, and mobility than any of its competitors. MigratoryData's support is also second to none.“ — Ryan Sokol, Director of Web Technology, Heritage Auctions
