About Regression Testing providers
QA teams re-testing existing features after changes to catch new defects.
Software testing and QA companies find defects before your users do, through manual testing, automation and specialist performance or security testing. Independent QA brings fresh eyes and dedicated tooling.
In the United States, Regression Testing Companies are concentrated around New York, San Francisco, Los Angeles, Austin, Chicago and Miami. Local rates sit at the upper end of the global ranges, so many buyers in the United States pair a local lead with nearshore or offshore delivery to manage cost.

How this list is compiled
Worldwide view: Clutch-verified specialists (registered businesses independently verified on Clutch with a working website, ordered by their number of verified client reviews) followed by established industry leaders. Country view: the main list is strictly local. It shows only Clutch-verified firms with an office in the selected country and established firms based in that country that the iCreativez research team selected for their scale and track record. Large international firms and remote teams that serve the country appear in a separate, labelled section and are never counted as local. Where we have not yet verified enough local firms, the page says so instead of padding the list. Minimum project size, hourly rates and team size are as published by each company in November 2026. Inclusion is free and not paid for. Providers can request a review via our contact page.
