In recent years, Backend-as-a-service providers such as Firebase and Supabase have become popular. One of their main innovation was to allow direct access to the database from the frontend. This makes the development of apps feel backend-less, as all logic to access data resides in the frontend. However, since all users using the app share the same database, the developer has to set access policies in order to determine which user can access what data. With Bazaar, the backend database is not only scoped to the app, but also to the user. This makes data access policies obsolete.
