Test Apps Built with Supabase | DidItWork

Supabase makes it easy to set up authentication and database access, but the security model depends heavily on correctly configured Row Level Security (RLS) policies. A single misconfigured policy can expose sensitive data or allow unauthorized modifications.

Real-time subscriptions and Supabase Auth flows add additional complexity. Session handling, token refresh, OAuth provider integration, and real-time event delivery all need verification with real user interactions, not just API tests.

RLS policy gaps are the most critical issue our testers find in Supabase apps. Users may be able to see other users' data, edit records they should not access, or bypass deletion restrictions. These are security vulnerabilities that demand thorough testing.

Supabase Auth issues are also common — OAuth redirects that fail, magic link emails that expire too quickly, and session tokens that do not refresh correctly. Real-time subscriptions may miss events or deliver duplicate updates during connection interruptions.

Provide your application URL and test accounts for different user roles. Our testers will verify that each role can only access appropriate data, that auth flows work end-to-end, and that real-time features update correctly.

For Supabase apps, we especially recommend the €30 or €45 test tiers to ensure thorough coverage of RLS policies and multi-user scenarios. The resulting report categorizes findings by severity, with security issues flagged as critical.
