The world's most advanced open-source database
Plain outbound link — no affiliate parameters, no tracking redirects.
PostgreSQL is listed in databases because it competes on utility: the world's most advanced open-source database. It's stewarded by a non-profit or foundation, which structurally protects it from acquisition-driven enshittification. Licensed PostgreSQL License; pricing: free. Technically it's lean — it runs comfortably on modest hardware, which is exactly the proof-of-work efficiency we rank for. This entry is provisional — the scores are seeded estimates pending our full manual rubric pass, and the verification date will appear here once complete.
