# About

## What is Roboflow Trackers?

Roboflow Trackers is an open-source Python library that provides clean-room implementations of leading multi-object tracking (MOT) algorithms: [SORT](../trackers/sort.md), [ByteTrack](../trackers/bytetrack.md), [OC-SORT](../trackers/ocsort.md), and [BoT-SORT](../trackers/botsort.md). The library is designed to plug into any object detection model through the [supervision](https://github.com/roboflow/supervision) library, giving you a single `tracker.update(detections)` call to add tracking to an existing detection pipeline.

Every algorithm is implemented from scratch following the original papers, with a shared interface and consistent parameter naming. The library ships with built-in evaluation tools for HOTA, IDF1, and MOTA metrics, a CLI for running trackers on video files, and dataset download utilities for standard MOT benchmarks.

## Who Built It?

Roboflow Trackers is built and maintained by the [Roboflow](https://roboflow.com) team. Roboflow builds tools and infrastructure for computer vision, from dataset management and model training to deployment and monitoring. The trackers library is part of the broader Roboflow open-source ecosystem that includes [supervision](https://github.com/roboflow/supervision), [inference](https://github.com/roboflow/inference), and [RF-DETR](https://github.com/roboflow/rf-detr).

A full list of contributors is available on the [GitHub contributors page](https://github.com/roboflow/trackers/graphs/contributors).
