Convex DB

Lattice-backed SQL database with JDBC and PostgreSQL wire compatibility — full relational tooling over convergent state.

Beta Open source Apache-2.0

Convex DB is a relational database built on the Convex lattice. It speaks SQL via JDBC and the PostgreSQL wire protocol, so existing tooling — drivers, ORMs, query builders, BI tools — works out of the box. Under the hood, rows and indexes are stored as lattice-structured data that merges convergently, giving you standard relational semantics on top of a decentralised, replicated state layer.

Intended for applications that need both the ergonomics of SQL and the properties of lattice storage: multi-peer replication, content-addressed history, and deterministic merges.
