Strangely despite the size of the online poker market there is only one company selling the two main HUDs.
Jivaro was an interesting market entry but then started monthly subscription which soon becomes more expensive than the one off costs.
And most strangely for such a large online market there was only one open source project which was poorly supported. https://sourceforge.net/projects/fpdb/
It would appear that the majority of players were happy to acquire and use either one or sometimes both of the market leaders.
