Nile

Nile is a Postgres service built for software that serves many customers from one application. It gives each tenant a virtual database while the data stays in one Postgres database.

Nile handles tenant separation inside Postgres, so developers can write application code against a single database. It supports the pgvector extension, which lets multi-tenant apps store embeddings for AI search per customer. The product also includes an auth feature and templates for building B2B apps, as shown on its site.

• One Postgres database with many tenant databases
• Tenant isolation without one database per customer
• pgvector support for embeddings
• Auth feature for user login
• Templates for B2B applications

SaaS teams that build multi-tenant products, especially B2B apps where each customer's data must stay separate. Startups that want Postgres without running many databases may also find it useful.

Nile is offered as a hosted service, and its pricing page lists the plans. Check the plan limits and the documentation before you move a production app onto it. Multi-tenant designs are easier to start with than to change later, so decide early how tenants will be separated and queried.
