Advanced open-source relational database with rich features
Popular open-source relational database optimized for web applications
From StackPrism’s curated notes. Pricing isn’t covered here: it changes often, so check each vendor’s pricing page.
Two open-source relational databases that every major cloud offers as a managed service, so availability rarely decides it. Teams usually weigh PostgreSQL’s extensions (PostGIS, pgvector) and richer types such as JSONB against MySQL’s long history in LAMP-style web stacks.
Release lines and end-of-life dates come from endoflife.date, release counts from deps.dev’s publish dates, and advisories from OSV.dev, counted once per flaw even when it’s listed under several ids, and checked against CISA’s list of vulnerabilities known to be exploited. Status and incident history come from each vendor’s public status feed; licences from each project’s licence file or the vendor’s licensing page, linked in the table.
The data refreshes every few hours and the time it was checked is shown above. There’s no pricing and no overall winner: which one fits depends on your constraints. To see how the versions you actually run hold up, check your repo.
