Multi-tenant SaaS applications need careful architecture from day one. This post covers the patterns used to build a robust authentication layer for a multi-tenant platform.
The Challenge
When multiple organizations share the same application, you need clear boundaries between their data while keeping the developer experience simple.
The Approach
Better Auth was chosen for its framework-agnostic design and built-in organization support. Combined with Xano's no-code backend, this gave the team rapid iteration without sacrificing security.
Key Takeaways
- —Always validate tenant context at the middleware level
- —Use row-level security as a safety net, not the primary control
- —Test with multiple organizations from day one
