Security checklist for user-submitted directory websites

Directory websites accept user-generated content, which means spam, bad links, unsafe text, and payment abuse are real risks.

Your baseline should include server-side validation, rate limits, manual approval, protected admin routes, webhook verification, and strict database policies.

With Supabase, Row Level Security is essential. Public visitors should only read published listings, users should only edit their own drafts, and payment status should only be changed by verified backend code.
