Prodseal vs Lovable Security Scan vs Supabase Security Advisor

Lovable’s scans are free (Lovable docs), and Supabase’s Security Advisor is built into the Supabase dashboard (Supabase docs). This page shows where Prodseal fits next to them. Every claim about Lovable and Supabase links to their own pages, and where their docs do not cover something, we write “not stated in its docs”.

Lovable has two scans in each project’s Security view. The Quick scan runs automatically when you publish. It checks database access rules, file storage rules, leaked-password protection, npm packages with known vulnerabilities, and MCP servers that are open without a sign-in (Lovable docs).

The Deep scan runs when you start it. It adds a review of your app’s logic and permissions for data the wrong people can see, endpoints anyone can trigger, unsafe input, leaked secrets, and payment and sign-in flaws, and it usually takes 3 to 13 minutes (Lovable docs). Both scans are free. Fixes go through the project chat, with 10 free fixes per account that each come back 24 hours after use, and credits after that (Lovable docs).

The Security Advisor sits under Database in the Supabase dashboard (Supabase docs) and runs queries on your database to find configuration problems (Supabase blog). Its checks include RLS turned off on a public table, RLS turned on with no policy, a policy that lets everyone through, sensitive columns that are exposed, a public storage bucket that allows listing, and security definer functions that anonymous users can run (Supabase docs).

You can run it in the dashboard, with the CLI command supabase db advisors (CLI reference), or through MCP (MCP docs). Each finding comes with a rationale and remediation steps (Supabase blog). Supabase also says many rules come with one-click fixes and that project owners get weekly emails about open security issues (Supabase blog). Our guide to checking RLS on every table shows how to work through its RLS findings.

Prodseal (prodseal.dev) is for apps built with Lovable, Bolt, Replit, v0 and similar tools on Supabase. It starts with a free check of your public URL, which needs no access at all. The free check looks at what any browser receives when it opens your app, such as keys in the JavaScript and the headers your app sends. You get a list of what it finds.

After you connect GitHub or Supabase, you get a free full report that checks database access rules (RLS), logins and admin checks, Stripe webhook signatures, API routes and edge functions, keys in your git history, storage buckets, and AI calls with no limit.

Use Lovable’s scans on every Lovable project. The Quick scan already runs when you publish, and the Deep scan is worth running before you share your app, because it reads your code and costs nothing.

Use Supabase’s Security Advisor on every Supabase project, whichever tool you built it with, because it runs its checks on your database directly. Clear its open findings before you share your app.

Use Prodseal when you want to see what the public sees without giving any access, when your app takes Stripe payments or calls an AI service, when an old key may still sit in your git history, or when you want tested fixes sent as a pull request or a kit instead of applying each change by hand. The three tools overlap on database rules, and that is fine.

Do I still need Lovable’s scans and Supabase’s Security Advisor once I use Prodseal? Yes. Keep running both. They are built in, they are good, and they see your project from inside the platform. Prodseal adds a check from the outside and covers a few areas their docs do not mention, such as keys in git history and AI calls with no limit.

What access does Prodseal need? The free check needs none, because it only looks at your public URL. The free full report needs GitHub, where Prodseal reads code and opens pull requests but never merges them, or Supabase, where the access is read-only. Code copies are deleted within 24 hours.

What is the difference between the $49 fixes and the $199 Done-for-you security fix? The $49 one-time fixes, per app, come first and cover the Critical and High issues Prodseal can fix automatically. Prodseal tests them on a sandbox copy and sends a pull request or a kit, and you decide what to apply. Anything it cannot fix automatically, such as rotating a leaked key, comes with manual steps.

The $199 one-time Done-for-you security fix, per app, is a separate offer that appears on your fix page and full report after your $49 fix is built, and only when it lists Manual steps. Prodseal fixes the Manual steps items from your free report, with a full refund if it can’t. It prepares the fixes as a pull request you approve and merge, using the GitHub access you already granted, and walks you through any dashboard or key steps, such as rotating a key in your own dashboard. Prodseal never asks for your secret keys, and nothing changes without your approval.
