TenantsDB

TenantsDB is an infrastructure platform designed to provide multi-tenant database orchestration with a focus on physical isolation for each customer. It addresses the challenges of traditional multi-tenant architectures, where customer data is either pooled in a single shared database or managed through manual, separate connections for each tenant. By giving every tenant their own dedicated database, TenantsDB aims to enhance security, prevent data bleed, and simplify compliance for organizations that require strict data segregation.

The platform supports four database engines—PostgreSQL, MySQL, MongoDB, and Redis—allowing users to provision, migrate, and query isolated databases for each tenant. TenantsDB manages all these databases through a single API, streamlining operations and reducing the need for a dedicated DevOps team. Its infrastructure is always on, ensuring that every tenant database is running without cold starts or connection delays, and it eliminates the need for row-level security policies by isolating data at the database level.

Schema management is automated through a versioned blueprint system. Users can design and connect their schema, track DDL changes internally, and deploy updates across all tenant databases with a single command. This approach helps prevent schema drift and removes the need for manual migration scripts, ensuring consistency across a large fleet of databases. TenantsDB also offers zero-downtime migrations using native replication, enabling the movement of tenants to dedicated hosts with minimal disruption and without changing connection strings. Safety backups are performed before each migration.

A notable feature is OmniQL, a built-in query language that allows users to write a single query, which is then compiled into the native syntax for each supported database engine. This facilitates cross-database querying while maintaining compatibility with existing database drivers. The platform is positioned as an open source solution, with its API and CLI tools supporting integration into existing workflows. TenantsDB is intended for teams and organizations seeking scalable, secure, and manageable multi-tenant database infrastructure without the operational complexity of manual provisioning and maintenance.
