Apache NiFi
What it is
Apache NiFi is free, open-source software for automating data flows between systems, including cybersecurity, observability, event stream, and generative AI pipelines. Its browser-based interface supports designing, controlling, and monitoring flows, with feedback as they run. NiFi records and indexes provenance data to track information through the system. Flow controls include guaranteed delivery, back pressure, prioritized queues, and quality-of-service settings for individual flows. Users can change dataflows in real time, applying changes to affected components without stopping the entire flow. Documented processors connect with Kafka, AWS, Azure, Google Cloud, databases, Slack, S3, and Salesforce. Security features include HTTPS, configurable authentication, multi-tenant authorization, and encrypted communications such as TLS and SSH. NiFi runs in a JVM on a host operating system and can be installed from a ZIP archive. It supports clustering and can be scaled down for edge devices through the MiNiFi subproject. The project lists a users mailing list and Slack workspace for help. Its security model makes users responsible for operating-system commands and custom code they configure. NiFi is free to download under the Apache License, Version 2.0.
