Edge-distributed SQLite — built on libSQL (a SQLite fork) and lets you replicate read replicas to hundreds of locations close to users.
Founded in 2023 by the ChiselStrike team. libSQL adds what stock SQLite doesn't want: a native HTTP protocol, WAL streaming for replication, attached encryption, embedded vector search. "Database branching" similar to Neon but at SQLite scale.
Sweet spot: latency-critical global apps where reads dominate and the schema is simple. Writes go to a primary in one region; reads happen locally at the edge. Competitor: Cloudflare D1 (also SQLite at the edge), Neon, PlanetScale.
