How do I know if my website is hackable?

Your website is hackable if it exposes a secret key, lets anyone read its database, or leaks its source and config, and all three are visible from the outside without breaking in. Scan your live URL and you will see the same openings an attacker would, worst first, so you can close them first.

The signs your site is hackable

  • A secret key in the browser. If a service-role or live payment key is in your shipped JavaScript, anyone can extract and use it.
  • An open database. If access rules are off, the public key in your app reads every row.
  • Leaked internals. A public .env, published source maps, or disclosed versions hand attackers a map of how to get in.

How attackers find them

They do not check by hand. They run automated tools that crawl sites and scan the public JavaScript for key patterns and open endpoints, thousands at a time. A new site with an exposed key is found in hours, not months. The check is cheap for them, which is why doing it yourself first matters.

If access rules are off, the public key in your app reads every row.

How to check yourself

Use the same method they do. Plaintext reads your live URL from the outside and reports what is exposed, worst first, with a fix for each. You see your site the way an attacker sees it, before they get there. The first scan is free.

Frequently asked

How do I know if my website can be hacked?

Check whether it exposes a secret key, lets anyone read its database, or leaks its source and config. All three are visible from your public URL. A passive scan reports them the same way an attacker would find them.

How do I check if my site is vulnerable?

Scan your live URL with a passive scanner. It reads the shipped JavaScript and the endpoints and flags exposed keys, open databases, and leaked internals, worst first, so you can fix the most dangerous ones first.
