Feature Comparison

Feature	Supabase	Turso
Database Engine	PostgreSQL with full SQL capabilities, extensions, and advanced features like JSON operations, full-text search, and complex queries	SQLite (libSQL) providing simpler SQL features with SQLite compatibility, ideal for lightweight operations but with some limitations on advanced database features
Global Distribution & Latency	Centralized database deployment with regional options, optimized for consistency over edge performance	Native edge deployment with embedded replicas across multiple regions, optimized for extremely low-latency reads at the edge
Built-in Services	Comprehensive backend services including authentication, file storage with CDN, Edge Functions, real-time subscriptions, and auto-generated REST/GraphQL APIs	Focused on database functionality with branching and schema migrations, requiring integration with separate services for auth, storage, and other backend needs
Real-time Capabilities	Built-in real-time subscriptions for live data synchronization across clients using PostgreSQL's replication features	No native real-time subscription features; would require additional tooling or custom implementation for live data updates
Self-hosting & Vendor Lock-in	Fully open-source with self-hosting option available, providing complete control and avoiding vendor lock-in	Relatively new managed service with limited self-hosting options, though SQLite compatibility makes data migration straightforward
Developer Experience	Comprehensive dashboard, extensive documentation, multiple client libraries, and automatic API generation from database schema	Simple integration with native framework support and SQLite compatibility making adoption easy for developers familiar with SQLite

Pricing Comparison

Both Supabase and Turso offer generous free tiers suitable for small projects and prototyping. Supabase provides more bundled services in its pricing while Turso focuses on database-specific metrics like storage and row counts, potentially offering better value for simple, globally-distributed data access needs.
