Every figure was read off the named company's own page on or since 2026-09-18; the URLs and the dates are at the foot of this page, and a job re-fetches each one on a schedule and fails when a figure is no longer on the page it came from.
| CRITERION | LAUNCHGUARD | SUPABASE SECURITY ADVISOR |
|---|---|---|
| What it costs | Free · Pro $29/month“Free $0 forever … Pro $29 / month”. The free tier is not a findings paywall: “It is not a paywall on findings.” | Not publishedThe advisors documentation states no price; they are part of the dashboard. |
| What it needs from you | A URL; sign-up to see full key details“Signing up (still free, no card) reveals the full leaked key and the fix prompt.” | Access to your Supabase project, through Studio, MCP, the CLI or the Management APIThe documentation was rewritten after this row was read on 4 September 2026. It now says "You or an agent can pull the same checks from: Studio: Security Advisor and Performance Advisor. MCP: get_advisors with type set to security or performance. CLI: supabase db advisors. Management API: security advisors and performance advisors." The dashboard is one of four routes rather than the only one. |
| Tests as a signed-in user | Yes“Logged-in tests included: we sign in as a real user, not just a stranger”. | Not publishedThe advisors inspect the project's own configuration; the documentation describes no test of a running app as a signed-in user. |
| Tests one user reading another's rows | Yes, as a saved guardThe free tier saves “up to 2 guards … for a cross-user leak, a payment bypass, or any rule you name”. | Not published |
| Re-checks after you ship | Every deploy, on Pro“It re-checks on every deploy, automatically, the moment you ship”. | Automatically"The advisors run automatically in Studio. After an authorized fix, rerun the relevant advisor and confirm that the finding no longer appears." |
| What you get | Findings, the request receipt, and a fix“Every finding, and the receipt: the exact request we sent and what your app sent back”. | A numbered list of lint findingsThe published check list includes “0002 auth users exposed” and “0003 auth rls initplan”. |
Every figure below was read off that company's own page; each source URL and the date it was read are listed at the foot of this page. BreachProbe is the publisher of this table and is not one of the 2 compared — it scores these rather than competing with them.
“Not published” means that company does not state the figure on the page cited at the foot of this page. It is not a claim that no such figure exists. A company that publishes no limit most likely has none — but “most likely” is not a fact, and this table prints what was read rather than what was inferred.
| TESTS AS A SIGNED-IN USER | whether the tool authenticates and probes as a real account, rather than only reading what an anonymous stranger can reach |
|---|---|
| TESTS ONE USER READING ANOTHER'S ROWS | the two-account test. It is the only check that can tell a working row-level security policy from one that is merely present |

When should I pick LaunchGuard, and when Supabase Security Advisor?
LaunchGuard — You ship every week and want the check to run itself. LaunchGuard is the only tool in this table that re-checks on every deploy automatically and keeps a history — “Memory: we remember every result and every call you made” — and at $29/month that is cheaper than buying a one-off report every month. It also covers Firebase, which BreachProbe does not. Supabase Security Advisor — You have not run anything yet. It is already inside the dashboard you are logged into, it runs on its own, and it sees things no external scanner can — an unindexed foreign key, a table with RLS disabled, a function with a mutable search path. Run it first, whatever else you do. It reads your project's configuration rather than your shipped app, which is why it is a different check and not a lesser one.
BreachProbe does not sell any of these and has nothing to gain from which one you choose — it scores them. Each case below is the one that option genuinely wins.

Prices and limits move, and a page quoting a stale one is worth less than a page quoting none. Every source is printed here so a reader can check it against the day they are reading this, and a job re-fetches each of these URLs on a schedule and fails when a figure above no longer appears on the page it came from.
