OpenDrop is a fully-featured pendant drop tensiometry software, allowing acquisition, analysis and fitting of pendant drop profiles to obtain surface and interfacial tension. OpenDrop now includes functionality for the measurement of contact angles.

It runs on Python 3.5+, and uses GTK+ 3 for the user interface, and OpenCV for image analysis.

OpenDrop is released under the GNU GPL open source license, and available for free.
