When managing multi-tenant systems, one common anxiety is that a coding error can unintentionally expose user data. Incorrectly routing a user’s data to the wrong tenant, or even distributing it to another user within the same tenant, is a very real fear. Additional precautions are necessary to safeguard against human errors. Supabase is an open-source platform that offers a viable alternative to Firebase. Similar to Firebase, it provides a frictionless user authentication process. Due to its integration with Postgres, it supports sophisticated access controls at a row level, aptly referred to as Row-Level Security (RLS). In this article, we’ll explore a concrete example of leveraging this feature and provide step-by-step implementation guidelines.
