# Fluentd

> Fluentd is an open source data collector for a unified logging layer. It decouples data sources from backend systems, so you can unify the collection and consumption of your data. Fluentd is a graduated project of the Cloud Native Computing Foundation (CNCF), and all components are available under the Apache 2 License.

This site is the home of the Fluentd project. It explains what Fluentd is, where to download it, which plugins are available, and how to take part in the community. The reference manual lives on a separate site, https://docs.fluentd.org.
