Turso

Turso brings SQLite to production with multi-region replication. Your database lives close to your users, with read replicas at the edge and a primary for writes. Built on libSQL, an open-source fork of SQLite that adds features like native replication and HTTP access.

Embedded replicas let you sync a local SQLite copy into your app for zero-latency reads, with writes forwarded to the primary. Works well with edge runtimes and serverless functions where connection pooling is a pain. Per-tenant database architecture is a first-class pattern.
