Multi-tenant Architecture
Build SaaS applications with true data isolation from day one. Each organization gets their own isolated environment, all running from a single Baasix deployment. No complex infrastructure, no data leakage risks.
SaaS-Ready from Day One
Multi-tenancy is typically an afterthought that requires significant architecture changes. Baasix makes it a first-class feature.
In Baasix, tenants (organizations) are a core concept. When a user creates an organization, they get a completely isolated data environment. Users can belong to multiple organizations with different roles in each. Queries are automatically scoped to the current tenant — there's no way for data to leak between organizations. You get all of this without managing separate databases or complex middleware.
- Automatic data isolation per tenant — queries scoped by default
- Users can belong to multiple organizations
- Different roles and permissions per organization
- Tenant switching without re-authentication
- Shared tables for global data (e.g., plans, features)
- Per-tenant configuration and customization options
- Single deployment serves unlimited tenants
Skip the Multi-tenant Headaches
Building multi-tenant from scratch is notoriously complex.
✓ With Baasix
- Tenant isolation built into every query automatically
- User-organization relationships handled by the framework
- Tenant context managed via tokens and middleware
- Single database with row-level tenant filtering
- Built-in admin UI for tenant management
✗ Traditional Approach
- Build custom middleware to filter every query
- Design and implement organization membership system
- Manage tenant context through request lifecycle
- Choose between database-per-tenant or complex filtering
- Build admin tools for tenant management
Multi-tenant Capabilities
Data Isolation
Every database query is automatically filtered by tenant. There's no code path where data can leak between organizations.
User Membership
Users can be members of multiple organizations with different roles in each. Invite flows and membership management built in.
Per-Tenant Roles
A user might be admin in one org and viewer in another. Permissions are evaluated in the context of the current tenant.
Tenant Customization
Store per-tenant settings, feature flags, and configuration. Each organization can have a unique setup.
Shared Global Data
Some tables can be global (pricing plans, feature definitions). Mix tenant-scoped and shared data as needed.
Tenant Switching
Users switch between organizations without logging out. The SDK and Admin UI handle context switching seamlessly.
Perfect for SaaS Applications
Any application serving multiple organizations benefits from built-in multi-tenancy.
B2B SaaS Platforms
Serve multiple business customers from one deployment. Each company gets isolated data, custom settings, and their own user management.
Agency Tools
Marketing agencies managing multiple clients. Each client is a tenant with separate campaigns, contacts, and analytics.
White-Label Products
Build one product, sell to many. Each customer can have custom branding and configuration while sharing the core platform.
Educational Platforms
Schools, districts, or companies as tenants. Students and teachers belong to their institution with appropriate access.
Multi-tenant FAQ
Can I disable multi-tenancy if I don't need it?
Yes. If you're building a single-tenant application, you can disable multi-tenancy and work with a simpler data model. It's optional but ready when you need it.
How is tenant isolation enforced?
Every query passes through middleware that adds a tenant filter. This happens at the framework level — you can't accidentally query cross-tenant data. It's enforced, not just suggested.
Can tenants have different schemas?
All tenants share the same schema. For tenant-specific customization, use JSON fields or a flexible key-value pattern. This keeps the system maintainable while allowing customization.
How do I handle tenant billing?
Baasix provides the multi-tenant foundation. Integrate with Stripe or your billing provider, storing subscription status per tenant. Use workflows to handle billing events.
