We’ve all been there.

You open a website, start clicking around, filling out forms, checking fields, urls etc – and 30 minutes later, you’ve barely scratched the surface. You missed that phone field that happily accepts “abcdef.” The image that never loaded. The dropdown with duplicate options and much more.

Manual exploratory/smoke testing is slow, inconsistent, and honestly – kind of boring.

That’s exactly why we built Exploratory Tester.

What is it?

Exploratory Tester is a free Browser Extension by SelectorsHub that runs 21 automated checks on any webpage with a single click. No setup. No configuration. No code.

Just install it, click the icon on any site, and within seconds you get a full breakdown of what’s broken, what looks suspicious, and what’s working fine.

What does it actually test?

Here’s what it catches – stuff that often slips through the cracks during manual testing:

Form Validation Gaps – Can someone type “hello” in a phone number field? Does the email field accept “not-an-email”? Is a required field actually enforced, or can you just skip it? Exploratory Tester checks email, phone, password, number, date, and required field validations by analyzing real behavior – not just HTML attributes.

Visual & UI Issues – Images that failed to load. Buttons that are disabled or too small to tap on mobile. Loading spinners that are still visible. Error messages sitting on the page. Dropdowns with only one option or duplicate entries.

Content Quality – Spelling mistakes in visible text. Missing placeholder text on inputs. Checkboxes and radio buttons without proper labels.

And more – Text areas without character limits, forms with no submit button, input fields that are unexpectedly disabled or read-only.

What makes it different?

A few things I’m genuinely proud of:

It thinks like a tester, not a scanner. It doesn’t just check if an attribute exists – it checks if validation actually works. It fills in bad data and sees what happens. That’s the difference between “this field has a type=email attribute” and “this field actually rejects invalid emails.”

Context-aware results. A checkbox inside a data table doesn’t need a label the same way a standalone form checkbox does. Exploratory Tester understands that and adjusts accordingly, so you’re not drowning in false positives.

One-click reports. Export your results as HTML, DOC, or PDF. Every report includes a page screenshot, URL, timestamp, and categorized findings – ready to share with your team or attach to a bug ticket.

Zero setup. No accounts. No API keys. No config files. Install the extension and you’re testing in under 10 seconds.

Who is this for?

• QA engineers who want a quick sanity check before diving into deeper testing
• Developers who want to catch obvious issues before pushing to staging
• Freelancers and agencies who need to audit client websites fast
• Anyone who’s ever thought “I wonder what’s broken on this page” and didn’t want to spend an hour finding out

Install it, open any website, click the icon, and see what it finds. I’d love to hear what you think.

If you’ve been doing exploratory testing and smoke testing manually, give this a shot. It won’t replace your brain – but it’ll definitely save you time and catch the stuff you’d normally miss on the first pass.

Built with ❤️ by the SelectorsHub team.
