What is Apache NiFi?

Apache NiFi is an open-source data flow automation platform that enables you to design, control, and monitor the movement of data between systems through a visual, drag-and-drop web interface — with zero coding required.

In simplest form, Apache NiFi is a data flow automation tool used to:

Collect data

Move data

Transform data

Route data

👉 Think of it like a smart pipeline builder where you visually drag-and-drop components to move data between systems.

At its core, NiFi solves a fundamental problem: how do you reliably move data from point A to point B — across different formats, protocols, and systems — without writing glue code for every integration?…
