# Awesome data annotation

A list of tools for annotating data, managing annotations, etc.



Contributing: I gladly accept additions to the lists below; please submit an issue or pull request with any updates.



***Just looking for a recommendation of the one best open source annotation tool?*** Me and several other people in industry and academia have independently found [**CVAT**](https://github.com/opencv/cvat) to be the best choice for Computer Vision tasks.
