Review on Font Pairer by Cesar Carter

The fact that it's available in multiple languages makes this tool very useful for multilingual projects! I can't think of anything about fontsphere that i don't like at all (other than maybe having to download more data).

If you're interested in working with other people but not sure where to start or if they would be willing/able to work together then using one anothers' resources will make things easier by comparison alone since both are open source - no need to ask them permission first etc., which could sometimes get tedious when dealing solely through social media such as Facebook & Twitter rather than direct emailing. We've been able use their software without any problems when we needed help from our graphic designers who were located remotely due to Covid-19 restrictions around office hours / remote access.
