Feature Comparison

Feature	PlanetScale	Retool
Primary Use Case	Database hosting and management with focus on scalability and safe schema changes	Rapid development of internal tools and admin interfaces that connect to various data sources
Database Interaction	Provides the actual database infrastructure with MySQL compatibility, handling storage, scaling, and performance	Connects to external databases (including PlanetScale) to query and display data through custom-built interfaces
Development Workflow	Git-like branching for databases with deploy requests for schema changes and non-blocking migrations	Visual drag-and-drop builder with version control for application development and collaborative editing
Scaling Capabilities	Automatic horizontal scaling powered by Vitess without requiring application code changes	Scales based on number of users and applications built, but doesn't provide database scaling itself
Customization & Flexibility	Limited to MySQL protocol and Vitess constraints (no foreign keys), focused on database operations	Highly flexible with 100+ UI components plus ability to write custom JavaScript and SQL queries
Target Audience	Developers and teams needing scalable MySQL databases with safe deployment practices	Developers and teams building internal tools, admin panels, and dashboards without full frontend development

Pricing Comparison

Both offer free tiers to get started, but serve fundamentally different purposes. PlanetScale pricing scales with database usage (storage, queries), while Retool pricing increases with team size and number of applications, potentially becoming expensive for larger teams.

Verdict

Choose PlanetScale if...

Choose PlanetScale if you need a scalable, managed MySQL database with advanced features like branching workflows, non-blocking schema changes, and horizontal scaling without managing infrastructure.
