Nstream is the company behind SwimOS, an open-source platform for building streaming data applications. Instead of polling databases, Nstream keeps application state continuously in memory as stateful "web agents" that ingest events from any source, compute in real time, and stream incremental updates to API clients and live user interfaces. The stack spans a JVM runtime (SwimOS for Java), TypeScript/JavaScript UI toolkits, a Rust runtime (swim-rust), and standalone WARP streaming clients, plus the commercial Nstream Platform and Nstream Jet low-code tooling for building real-time applications used in asset monitoring, fraud detection, customer 360, and business visibility across retail, financial services, telecommunications, and transportation & logistics.
