Public sentimentReddit and GitHub users broadly praise the value and capability, while flagging hidden self-hosting costs, security worries, and uneven development pace.11The only quotable review in the sources is vendor-published and positive; independent review volume found was thin.
Biggest gotcha"Free" still costs: you pay for server hosting, Docker, and your time12Fixed support pricing replaces licenses, but tier prices aren't public . ask before budgeting
