Our take
Pick PlanetScale if you're on a app team who will start Base at $5/month (single-node Postgres) or $30/month (PS-10 arm64 HA in us-east-1) while they open a first Cluster configuration screen, then add $5 PS-DEV branches or extra production SKUs when they need a deploy-request workflow. Pick Supabase MCP if you're on a app team whose coding agent should migrate and query the same Supabase project they already pay
