Fluvio is a distributed data streaming platform that moves records between your applications on partitioned topics and transforms them in flight with WebAssembly modules before they land anywhere. Producers publish to topics and consumers read at their own pace, with client libraries for Rust, Python, and JavaScript plus a full command line for producing and consuming interactively. SmartModules are reusable WebAssembly functions that filter, reshape, and enrich records inside the stream, so cleanup and routing logic runs once at the platform layer instead of inside every consumer. Stateful DataFlow builds continuous processing on top of the same streams, keeping state across records to aggregate, join, and react as data arrives. Inbound connectors collect from HTTP endpoints, webhooks, MQTT brokers, and Kafka clusters, and outbound connectors deliver to HTTP, SQL databases, and Kafka, with a development kit for building connectors to your own systems. A local cluster starts with one command for development, and the same platform deploys on Kubernetes for production streaming at the edge or in the cloud. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.
