The best Managed databases

Every option ranked — open-source, self-hostable, and commercial — by our transparent Sovereignty Score, with honest trade-offs so you choose what fits you, not us.

Someone else runs your database. The convenience is real and so is the markup — and this is the category where licences changed most in the last five years.
