Two autonomous QA agents launched within four days of each other.

Replay QA ("tells you what is broken before your users do") hit #4 on Product Hunt July 20 with 415 votes, four days after Manta AI shipped autonomous web app testing. Two independent launches in the same narrow slot inside a week is a category forming, not coincidence. Both target QA headcount rather than the test-authoring tool, meaning the displaced spend is salary budget, not a Cypress or BrowserStack line item. The architectural common denominator: an agent that decides what to test rather than executing a script a human wrote. Given the 86% error-handling miss rate in agent-authored PRs, I'd want to know whether these agents have the same blind spot as the agents writing the code.
