Network Performance Monitoring

A major network service provider wanted to improve real-time operational data for their technicians. Prior to introducing Swim, this information would take several hours to analyze, causing network technicians to be unaware of new service outages. Working with Swim, the service provider unified data streams from their existing network infrastructure to create a single app that monitors thousands of cell towers and millions of subscribers in real-time.

The Swim Platform is a self-managing runtime for operating commercial SwimOS apps.


An open source platform for building stateful, real-time apps from streaming data.


How Real-Time Apps
Should Work

Swim was founded in 2015 by the creators of the open source swimOS platform. We developed the Swim platform as the best way to build intelligent real-time apps, without worrying about distributed hardware infrastructure and constantly wrangling distributed state. Swim is based in Campbell, CA and also has offices in Cambridge, UK.

Production Ready

The Swim Platform provides real-time visibility, management tooling and automation features to operate your real-time swimOS apps at any scale.
