AuditYourApp vs SupaGuard

AuditYourApp vs SupaGuard: Which Supabase Security Scanner Is Right for You?

Both AuditYourApp and SupaGuard aim to solve a critical problem: ensuring your Supabase application's Row-Level Security (RLS) policies are correctly configured and your database is not leaking sensitive data. However, they take meaningfully different approaches.

Scope of Coverage

AuditYourApp is designed as a multi-platform BaaS security scanner. While Supabase scanning is its core strength, it also covers Firebase projects and mobile applications (APK and IPA reverse engineering). This makes it a strong choice if your stack spans multiple backend-as-a-service platforms or if you ship native mobile apps that embed Supabase credentials.

SupaGuard, by contrast, focuses exclusively on the Supabase ecosystem. This narrower scope can be an advantage if you only use Supabase and want a tool that is deeply specialized in that one area. Specialized tools sometimes catch edge cases that broader tools miss, simply because the development effort is concentrated on a single target.

RLS Policy Analysis

AuditYourApp performs automated RLS policy fuzzing, which means it actively tests your policies by attempting various data access patterns against your tables. This goes beyond static analysis by simulating real attack scenarios. The scanner processes tables in concurrent batches and uses AI to interpret the results, generating human-readable reports that explain not just what is vulnerable but why it matters and how to fix it.

SupaGuard typically offers static analysis of RLS policies, checking for common misconfigurations and missing policies. This approach is faster and less intrusive but may miss vulnerabilities that only surface during dynamic testing.

Reporting and Remediation

AuditYourApp generates AI-powered vulnerability reports that include severity ratings, detailed explanations, and remediation guidance. Reports can be shared via Slack notifications and accessed through a web dashboard. The schema visualization feature helps teams understand their database structure and identify where security boundaries should exist.

SupaGuard provides its own reporting format, generally focused on listing policy issues with basic remediation suggestions. The output tends to be more technical and developer-oriented.

Pricing and Flexibility

AuditYourApp uses a credit-based system, which means you pay per scan rather than committing to a monthly subscription. This is advantageous for teams that scan periodically, such as before major releases, rather than continuously. SupaGuard typically uses a subscription model, which may be more cost-effective for teams running daily scans.

When to Choose Each

Choose AuditYourApp if:

• You use both Supabase and Firebase
• You need mobile app security analysis
• You want AI-powered, human-readable reports
• You prefer pay-per-scan pricing
• You need active RLS fuzzing rather than static analysis

Choose SupaGuard if:

• You exclusively use Supabase and want a deeply specialized tool
• You prefer a subscription model for predictable costs
• You want a simpler, more focused tool
• You need self-hosted deployment options

Conclusion

Both tools address a genuine gap in Supabase security tooling. AuditYourApp offers broader platform coverage and more advanced testing techniques, while SupaGuard provides focused Supabase-specific analysis. For teams building exclusively on Supabase with straightforward security needs, either tool can be effective. For teams with multi-platform stacks or complex RLS configurations, AuditYourApp's broader feature set and dynamic fuzzing capabilities make it the stronger choice.
