**APIs profiled:** 3

Bytewax is a Python-native distributed stream processing framework built on a Rust runtime. Developers define dataflows using the bytewax.dataflow API, composing operators (map, filter, reduce, joins, windowing) over connectors for Kafka, files, stdio, demos, and custom sources/sinks. The Bytewax Platform layers a self-hostable Kubernetes-based control plane on top, managed with the waxctl CLI and Helm chart, with deployment targets that include AWS, GCP, and the AWS Marketplace.
