Turso is a globally distributed, edge-first database built on libSQL (an open-source SQLite fork). It bridges SQLite's lightweight schema with enterprise replication, allowing developers to query data at the edge with millisecond latency. Unlike traditional SQLite (single-file, local-only), Turso adds distributed read replicas, API access, and backup without sacrificing SQL compatibility. You interact with Turso via libSQL SDKs (Node.js, Python, Rust, Go) or HTTP APIs. Data syncs automatically across regions; you pick primary location (e.g., Frankfurt) and read replicas (e.g., Sydney, São Paulo). Applications connected to edge replicas see consistent, low-latency reads.
