Most hosted databases are run by companies that took outside money. That money is not free: it arrives with a growth curve attached, and the curve is what eventually decides that the free tier has to go, that the price has to double, or that the whole thing is worth more to an acquirer than to the people using it. None of that is villainy. It is arithmetic, and it is baked in from the first funding round.
briven has not taken that money and is not going to. It is paid for by the people who use it, which means the only way it survives is to remain worth paying for. That is a slower business and a much more boring one, and it is the entire reason the thing exists.
The practical consequence is that briven is allowed to be small. It does not need to reach a hundred million rows under management to justify itself. It can say no to a feature, and it can say plainly that it does not do something — which is why the security page has a section listing what briven cannot do, and why the homepage names three things it has decided never to build.
