PWA scalability challenges in multi-tenant applications

Multi-tenant PWAs require isolation of cache, storage, and state per tenant.

In SaaS PWAs, multiple organizations share the same app instance. Each tenant requires isolated caching strategies, IndexedDB namespaces, and authentication contexts. Without isolation, data leaks or cache collisions can occur. Techniques include cache key prefixing, tenant-scoped service worker logic, and separate IndexedDB databases per tenant.
