What streaming data applications enable

Full stack data streaming

Most real-time data stops flowing before it reaches the application layer. Nstream picks up where the data pipeline leaves off and drives stateful services, streaming APIs, and real-time UIs entirely on push.

Model real-time state

Turn streaming data into real-time state. Instantly compute the consequences of every state change.

Why streaming data applications matter

Expect more from streaming data

Every data pipeline ends with an application. Realizing the full potential of data in motion requires an application platform that can keep up.

Latency is loss.
Backlogged data is as lost to the present as deleted data is lost to the future. Nstream relies on cache coherence rather than messaging semantics to ensure the lowest possible end-to-end latency.
Data depreciates.
Real-time data has to be used before it becomes useless. Optimized for data locality to minimize network hops, Nstream evaluates stateful business logic the instant new data arrives.
Time is money.
Local memory is a million times faster than the remote memory. Nstream gives business logic memory latency access to related context by asynchronously materializing it.
Causes have effects.
No event happens in isolation. Nstream cascades streaming data across a distributed state machine to infer the downstream implications of upstream observations.
Inaction has consequences.
Insights are only as valuable as the actions they trigger. Nstream acts on streaming data as it flows by chaining the output of any state to the input of any computation.
The future is observable.
If you understand the present, you can see the future coming. Nstream keeps humans in-the-loop with interactive user interfaces that update at the speed of change.

How streaming data applications work

Built from first principles to be stateful and streaming

Nstream builds on the open source foundation of SwimOS, the first full stack streaming application platform. SwimOS provides stateful services, streaming APIs, and real-time UIs. On top of this Nstream adds customizable solution kits, configurable data connectors, and a scalable control plane.


Turn streaming data into real-time state.

Convert streaming data into real-time states and instantly analyze the outcomes of each state change in real-time via Stateful Services.

Stream incremental updates to API clients.

Deliver streaming application output for any single or aggregate entity, and dynamically subscribe only to the precise data you require.

Interact with live data visualizations.

Engage with your business through a live windshield, not just another dashboard. Gain real-time insights that offer a comprehensive understanding of the overall business as well as granular operations, enabling informed decisions and real-time responses.

Nstream Platform

Incorporate Data from any source.

Source and sink connectors to seamlessly receive and send data to the most popular streaming data systems (Kafka, Pulsar, Kinesis) and data at rest systems (Databases, mainframes, legacy applications).

Scale up in the Cloud or down at the Edge.

Control Plane enables you to effortlessly scale to enterprise-level workloads, easily deploy and manage your streaming data applications across various environments.

Compose Apps from Building Blocks.

App toolkits provide readily available architectural and functional templates to get you started quickly to build full-stack streaming data applications for your business needs.
