Supabase

Supabase security, configuration, and development services

Supabase is the default backend for Lovable and a popular choice for AI-built apps. Its power comes from PostgreSQL and Row-Level Security — but most AI-generated apps skip the security configuration entirely.

Common Supabase issues we find

Real problems from Supabase codebases we've reviewed.

Security

Missing Row-Level Security policies

Tables without RLS policies are accessible to anyone with the anon key. This is the #1 security issue in Lovable and Supabase-based apps.

Security

Overly permissive RLS policies

RLS policies that use 'true' as the condition, effectively making the table public while giving a false sense of security.

Security

Service role key in client code

The service_role key (which bypasses RLS) exposed in frontend code, giving attackers full database access.

Performance

Missing database indexes

Queries slow down as data grows because commonly queried columns lack indexes.

Performance

Unoptimized real-time subscriptions

Subscribing to entire tables instead of filtered rows, consuming bandwidth and processing unnecessary updates.

Deployment

No database migrations

Schema changes made directly in the dashboard without migration files, making it impossible to reproduce the database in another environment.

Security

Auth configuration gaps

Email confirmation disabled, weak password requirements, or missing redirect URL restrictions in auth settings.

Security

Storage bucket permissions

Storage buckets set to public or with overly permissive policies, allowing anyone to upload or access files.

Frequently asked questions

Is my Supabase setup secure?

If you used an AI tool to build it, almost certainly not. Broken access control is the #1 risk on the OWASP Top 10 (2021), appearing in 94% of tested applications. The most critical issue in AI-generated Supabase apps is missing or misconfigured Row-Level Security (RLS) policies. We audit your entire Supabase configuration including RLS, auth, and API exposure.

What is Row-Level Security and do I need it?

Row-Level Security (RLS) is a PostgreSQL feature that controls who can read and write each row in your database. Without it, anyone with your Supabase anon key can access all your data. According to the Supabase documentation, RLS should be enabled on every table that stores user data. You absolutely need it — it's the single most important security control for Supabase apps.

Can you set up Supabase for my app?

Yes. We configure authentication, database schema with proper RLS, storage buckets, edge functions, and real-time subscriptions.

How do I migrate my Supabase database?

We create proper migration files from your current schema, set up a migration workflow, and ensure your database is reproducible across environments.
