Tynker on Ubuntu Linux

My kids play Minecraft on a 10 year old computer which only has 2 gb memory and runs Ubuntu Linux 16.04. Ubuntu Linux includes Firefox web browser as well as OpenJDK java runtime to run Minecraft jar files.
Does Tynker support Ubuntu Linux 16.04?
Can my kids create Minecraft mods using Tynker on Ubuntu Linux 16.04? Tynker looks interesting, but I am concerned that the Tinker website only mentions Windows/Mac and not Linux.
