What is QA.tech?
QA.tech uses an automated browser to test web applications. A customer adds an application or environment to QA.tech, defines a test goal, and sends the agent through that configured site. The agent can also identify possible test cases before it runs them.
During a test, the browser navigates pages, clicks controls, fills forms, and checks outcomes. These are real application interactions, not a background scan of every public URL on a domain. They may reach login screens, staging hosts, or other routes that the QA.tech customer has deliberately made available to the test.
QA.tech describes this traffic as authorized functional and regression testing. It does not use the bot to index the public web or bulk-scrape arbitrary sites. Although AI helps decide how a test is executed, QA.tech does not document this bot as collecting material for model training or an AI search product. Allowing it has no direct effect on search inclusion or citations in AI answers.
Current QA.tech bot documentation says browser requests append QATechBot/1.0 (+https://docs.qa.tech/bot) to a normal Chromium user agent. A standalone request, including a request for robots.txt, can use that value by itself. This page retains QA.tech as its catalog token, so log and firewall checks should account for the operator's more specific current suffix.
A user agent alone is easy to copy. QA.tech publishes its current IPv4 prefixes at https://app.qa.tech/.well-known/qatech-ips.json, and its documented egress addresses resolve to bot.qa.tech with matching forward DNS. Top-level navigations may also carry HTTP Message Signatures. Images, scripts, and stylesheets are usually unsigned, so signature checks cannot cover every request in a browser session.
QA.tech says its policy checks use the QATechBot/1.0 identity and honor normal robots rules for customer-configured URLs. Access controls still matter. If the application sits behind a WAF, CAPTCHA, or IP restriction, an approved test may fail until the QA.tech addresses or verified bot traffic are allowed through.
