tl;dr: Supabase is acquiring Turso to address the massive database demand created by AI agents, which are spinning up millions of databases for prototypes and apps. Turso's Rust-based SQLite rebuild and architecture—where a single server manages millions of on-demand databases—complements Supabase's Postgres offering, providing a path from cheap SQLite prototypes to production Postgres. Both products will continue operating independently, with Turso's Glauber Costa leading the new agentic infrastructure effort.
