Retool Database provides built-in PostgreSQL database for Retool applications, enabling internal tool development without external database setup. Included in Retool pricing: Free tier (limited); Team at $10/user/month; Business at $50/user/month; Enterprise custom. The database is fully-managed PostgreSQL accessible from Retool apps, workflows, and external connections. Features include GUI table editing, CSV import, automatic backups, and standard PostgreSQL compatibility. Use cases include prototyping (build apps before setting up production database), admin tools (store configuration, audit logs), and simple CRUD applications. AI features within Retool include AI-powered app generation from descriptions. Limitations: sized for internal tools rather than production workloads, Retool-ecosystem lock-in. For comparison: similar to Supabase but tightly integrated with Retool’s app builder. Best suited for teams building internal tools who want integrated database without infrastructure management. Page should cover: database capabilities and limitations, integration with Retool apps, pricing tiers, comparison with standalone databases, and appropriate use cases.
