Base44 Can Now Send AI Hackers at Your App Before Real Ones Find It

Here is the uncomfortable truth about the app you just shipped. It passed every check you ran, and you still have no idea what happens when someone actually attacks it.

Base44's built-in security scan, which I covered two weeks ago, is good at what it does: it checks your code for exposed secrets, bad data permissions, and vulnerable logic. But it is a static check. It reads your app. It never tries to break in.

On October 27, Base44 closed that gap. Connect Tenzai and you can now run an AI penetration test against your published app, from the same Security page you already use.

What Tenzai actually does

Tenzai is an AI penetration tester. You start the test, and it attacks your live app the way a real attacker would: it tries things, it looks for doors you left open, it keeps going. Crucially, it tests the pages people see after they sign in, not just your public screens.

The part I appreciate most is how the login is handled. Base44 gives Tenzai a temporary test login for your app. Your own credentials are never shared, and the test user is disposable by design. When the test finishes, you get an email, and the full report lands in your Tenzai dashboard: what it managed to do, and how to fix each thing it found.

How to set it up

1. In your workspace sidebar, click Connectors, then Add connector, then search for Tenzai.
2. Paste your Tenzai access key, or register from inside the connect window and Tenzai will set up a dedicated organization for your workspace.
3. Open your app's Security page and start the pentest.
4. Wait for the email, read the report in your Tenzai dashboard, fix what it found, and run it again after you republish.

Two things worth knowing before you start: tests are billed to your Tenzai account and do not use Base44 credits, and you need the Builder plan or higher. Once Tenzai is connected, workspace owners and admins can run pentests on any app in the workspace, so it scales across a client roster.

When to run one

Base44's own guidance is sensible, and I would follow it literally. Run a test:

1. Before you launch your app.
2. After big changes, especially adding sign-in, payments, or new user roles.
3. When a customer or an audit asks for one.

One catch: a test only covers the version of your app that is published when it runs. That means this is not a one-time checkbox before launch day. It is a tool you reach for every time the app materially changes.

Why this matters if your app takes money

If you charge for anything, your app stores emails, payment identifiers, or behavior data that would embarrass you if it leaked. The security scan keeps your code clean. The pentest tells you whether the machine holds up under a live beating. Those are different questions, and now you can answer both.

There is a commercial angle too. If you sell to businesses, procurement teams increasingly ask for security evidence before they sign. A pentest report with a date on it is a real answer to that question, and most solo builders have never had one.

My take on the economics

Traditional penetration tests cost thousands of dollars and take weeks of scheduling. That pricing made them a enterprise ritual. An AI pentest you run in an afternoon changes the math: you can test after every meaningful change instead of once a decade.

My recommended sequence: run the free security scan first, fix what it flags, use the new private-fields detection to hide emails and payment identifiers on readable records, then let Tenzai loose. Fix what it finds, republish, run it again before launch. Cheap, repeatable, and it compounds.

Scan versus pentest, in plain terms

The security scan reads your app's configuration and code and flags what should not be the way it is: entities anyone can read when they should need permission, secrets sitting in the wrong place, logic a reviewer would frown at. It is fast, free, and you should run it constantly, because it catches the mistakes you make on a random Tuesday while adding a feature.

The pentest behaves like an opponent. It starts from your public pages, tries to get further than it should, pokes the sign-in flow, and tries things on the screens behind it. It answers a question no static check can: given this app as deployed right now, what can an attacker actually do?

You need both. Scan catches the stupid mistakes cheaply. Pentest catches the clever ones.

How to read the report

A pentest report is a list of things the attacker managed to do, ranked by severity, each with a fix. The findings that matter most on small apps are usually boring ones: a screen that renders for people who never signed in, a role that can see more than its job requires, data exposed on records that did not need public read access. When the report comes back, resist the urge to skim. Fix the top severity items first, republish, and run the test again to confirm the fix held. That second run is the part most people skip, and it is the difference between hoping and knowing.

Make it a rhythm

Here is the cadence I would run if I were selling apps built on Base44:

1. Scan after every build session. It is free, so there is no reason not to.
2. Pentest before every launch that adds sign-in, payments, or new roles.
3. Pentest again after you fix what it found, to confirm the fix.
4. Offer the report to business clients as part of the handoff. It builds trust and it justifies a line on your invoice.

The whole point of this feature is that testing stops being a ceremony you schedule and becomes a habit you can afford.

Ship the app, scan it, then let AI hackers break it before real ones get the chance: https://base44.pxf.io/c/2084737/2049275/25619?trafcat=base
