One tool, six audits

Everything a QA team checks — in a single scan.

Point StressProbe at a URL, tick what you want, and it drives a real browser through your site the way a tester would.

Security

Security scan

Checks security headers, SSL, and hunts your live code for leaked API keys, passwords and private tokens.

Accessibility

WCAG 2.1 audit

Flags the accessibility problems that get small businesses sued — missing labels, poor contrast, unlabeled images.

Data privacy

Access-control check

Confirms one customer can't read another's data — the leaks that quietly expose private records (IDOR / broken permissions).

Performance

Load test

Hits your key pages with many visitors at once and reports how fast it responds — before a rush of leads finds out.

Visual

Visual regression

Remembers how your pages look and flags when a change breaks the layout — so a bad deploy never ships silently.

AI tester

AI functional testing

An AI tester clicks through your site like a real person and writes up what broke — optional, using your own key.

From download to report

Three steps. No coding, no setup.

Open the app

Unzip the folder and double-click StressProbe. The dashboard opens in your browser — nothing to install, nothing in the cloud.

Paste a URL

Enter the website you want to check and tick the audits to run. Add a test login if you want the deeper, logged-in checks.

Get your report

Watch it scan live, see every issue graded by severity, and download a polished Word report you can hand to a client or developer.

Private by design

It runs on your computer — not someone else's cloud.

StressProbe does its work locally. The only thing it talks to is the website you're testing. No accounts to create, no data uploaded, nothing to leak.

Nothing uploaded. Your reports and logins stay on your machine.
Works offline. Except for the sites you point it at.
AI is optional & yours. Turn on the AI tester with your own key — your usage, your account.
Simple pricing

Try it free. Upgrade when it pays for itself.

One caught security hole or broken checkout is worth more than a year of StressProbe.

Questions

Good to know.

Do I need to be technical?

No. You unzip a folder, double-click one file, paste a web address, and click Run. The results are written in plain language and colored by how serious each issue is.

Is my data safe?

Yes. StressProbe runs entirely on your own computer. It doesn't create an account or upload anything — the only thing it contacts is the website you're testing.

Do I need to install anything?

No installer. You download a folder, unzip it, and double-click StressProbe.exe. Everything it needs is inside — a browser engine and the tools all come bundled.

What are the AI features and do they cost extra?

The AI tester (which clicks through your site and writes up bugs) is optional. To switch it on you add your own Anthropic API key, so any AI usage is billed to you, not us. Every other audit works without a key.

Which websites can I scan?

Any site you own or have permission to test — your own business site, your clients' sites, or a staging copy. The deeper logged-in checks just need a test login.

Does it work on Mac?

The one-click app is Windows today. If you need macOS, get in touch — it's on the roadmap.
