LabelMe is an actively developed open source graphical image annotation tool inspired by the app of the same name released in 2012 by MIT CSAIL.
It is capable of annotating images for object detection, segmentation, and classification (along with polygon, circle, line, and point annotations). It also supports annotating videos.
The app is cross-platform and runs on Ubuntu, macOS, and Windows using Qt4 (or Qt5) and Python (2 or 3). A docker container is also available.

With Roboflow, you can deploy a computer vision model without having to build your own infrastructure.
