LokaDB is a Postgres wire-protocol proxy that lets a multi-tenant SaaS store selected tenants' rows in each customer's own Postgres, without rewriting the application — it uses partitioned tables and postgres_fdw to route statements per organization. It is technically ambitious and well-tested against unmodified frameworks, but its usefulness depends on a specific enterprise-compliance niche.

Target audience: backend devs and devops building multi-tenant SaaS with Postgres
