Mote

2019 review: Mote VTT seems to be discontinued, homepage is offline, and facebook page is deleted. Last activity in their subreddit or associated reddit user was from April 11, 2018.

Mote was a free VTT app made in Java by Idle Ideas Inc. It started as a fork from MapTool that has gone quite beyond its parent project.

Idle Ideas Inc. later had a Kickstarter for "Sandstorm", a cloud-based service as support for Mote.

Latest update is from March 2018.
