Tenant isolation ensures that one tenant's data and actions do not affect others. It protects privacy, security, and prevents data leaks between tenants sharing the same app instance.

What is a common pattern to identify tenants in Remix routes?

A common pattern is to use dynamic route parameters like "/app/:tenantId" to capture the tenant's identity from the URL. This lets loaders and actions fetch and handle data specific to that tenant.
