AI platforms currently categorize Supabase as the go-to for rapid application development, while PlanetScale is consistently surfaced for high-concurrency, mission-critical infrastructure.", "tldr": "Supabase dominates AI visibility for startups and full-stack developers due to its integrated feature set (Auth, Storage, Edge Functions).
