PXxi

PXxi is a software platform for real-time data processing, analytics, and visualization. It provides a unified runtime that handles both streaming and batch workloads. Built around a modular plugin system, PXxi aims to allow users to connect data sources, process events, and render results without rewriting core components.

Its core runtime executes event-driven pipelines. A plugin architecture supports connectors, processors, and visualization widgets. The platform ships with PXQL, a SQL-like query language optimized for streams, and offers SDKs for Python and JavaScript to implement custom logic. Data sources and sinks are accessed through connectors, which can be extended to support new platforms.

Data moves from sources through processors and into dashboards or storage. Features include windowing, stateful processing, backpressure management, and built-in visualizations. PXxi can be deployed on-premises, in cloud environments, or in containers, and supports orchestration via common tooling.

PXxi emerged from a community effort to address the need for a flexible analytics platform that could unify disparate data formats. Early development focused on modularity and performance, with rapid iterations through open-source contributions. The project is governed by an open governance model and releases under an open-source license.

Adopters cite rapid prototyping, easy integration of heterogeneous data, and scalable dashboards. Critics note a steady learning curve and variability in plugin quality.
