Supabase anonymous keys are public by design, not a security risk

By PulseAugur Editorial · [1 sources] ·

Developers building applications with Supabase, Lovable, Bolt, or Cursor have raised concerns about the visibility of their anonymous keys in the browser. However, these keys are intentionally public and grant access only to what is permitted by the user's grants and Row Level Security (RLS). The primary risks to security involve the inclusion of service_role keys in bundles, the exposure of open tables, or the implementation of write policies that allow unrestricted access. AI
