I think this could help me keep track of my increasingly complex infrastructure. But this program is going to have access to... a lot of very sensitive stuff. All the private keys to login... I'd feel much more comfortable if it were open source somehow.
Well it is open-core on GitHub right now. I think full open source is going to be difficult if you're trying to sell it. At least in the desktop application space with no account setup or other service dependency it's complicated as anyone could circumvent paying by cloning it and commenting out a few lines.
But I can fully understand your concerns, establishing trust is important. At the end of the day it's up to you whether you feel comfortable enough with it.
