About MigratoryData
MigratoryData is a high-performance, distributed WebSocket messaging server built for enterprise-grade real-time communication at massive scale. It can handle up to 10 million concurrent clients from a single commodity server, making it one of the most cost-efficient solutions for streaming real-time data to web, mobile, and IoT devices. Built around a publish/subscribe API, MigratoryData supports client libraries for all major platforms and languages including JavaScript, iOS, Android, Java, C#, Python, Node.js, PHP, Dart, and MicroPython. Its active/active clustering architecture ensures high availability with automatic failover, message ordering guarantees, and distributed in-memory caching — even in the face of hardware failures or network disconnections. MigratoryData is trusted by organizations in financial services, online auctions, sports broadcasting, and enterprise communication for use cases where sub-millisecond latency and guaranteed message delivery are non-negotiable. Unlike cloud-based messaging services, MigratoryData is self-hosted, giving teams full control over their infrastructure, data sovereignty, and cost predictability at scale.
