LokaDB is a Postgres wire-protocol proxy that lets multi-tenant SaaS applications store selected tenants' data in their own external Postgres databases without code changes. It uses partitioning, foreign data wrappers, and an outbound mTLS tunnel, providing a novel solution for data residency and customer-managed data. The project is technically sophisticated and targets a real enterprise need.

Target audience: backend developers, SaaS architects, DevOps engineers
