It's an MIT-licensed auditor that probes anonymously to confirm three classes of leak in Appwrite projects:

• "any" role grants left on collections after prototyping
• Public Storage buckets with broad read permissions
• Unprotected execute-functions exposed to anonymous

Outputs an HTML report with copy-paste fix snippets. Hosted run on Apify (no install): apify.com/renzomacar/appwrite-security-auditor.

Thanks for the review! Fixed both points: moved the entry to the Tools section (where it belongs as a tool, not an article/learning resource) and shortened the description to match the existing style. Latest commit reflects both changes.
