How we ranked these
We ranked tools that use AI to design, draw or edit a schema first, then AI-assisted database IDEs and clients, then change-governance platforms, using each maker’s own published features and prices. The old list also had Prisma, Microsoft SSMS with GitHub Copilot and Amazon Q Developer, which we replaced with DrawSQL, SqlDBM and DBeaver because we could source AI schema or diagram features for those on their own sites. Facts are taken from each maker's own published information; check the official site before you buy.
