QA companies in this catalog, page 4
130 software testing companies, each described by the same fields and each fact carrying the source it came from. Filters combine on this page only; a single filter has its own page with an ordered table and the reasoning behind the order.
130 profiles, most recent check September 6, 2026. Sources are listed on the sources page.
QA Rating is published independently, and its publisher owns no company listed in this catalog. Position in a ranking cannot be bought. Paid options are limited to the extended profile, labelled sponsor slots and lead forms, and none of them affect tags or order. Ordered by the number of verified reviews on external platforms, highest first. Companies with an equal count are ordered by name. A ranking states its own basis on its own page and groups companies by applicability tag, which this list does not do. What each field means is on the methodology page.
