What this tool checks

Frequently asked questions

Why detect a competitor's tech?

It tells you how a site is built, what it might cost to match, and which plugins or platforms power it.

Can detection be wrong?

Sometimes — sites can hide or spoof signatures, so treat results as strong hints, not certainties.
