Spur is an agentic QA platform for websites and mobile apps. Autonomous AI browser agents navigate your site the way real customers do, executing full end-to-end journeys across checkout, account creation, product browsing, promo redemption, and more. They see, decide, and interact like a human would, catching functional and content bugs across desktop web, mobile web, and native apps before your customers do.

Tests are written entirely in natural language, no code, no selectors, no brittle scripts. When your site changes, tests adapt. That means no maintenance backlog, no broken suites after every deploy, and no QA bottleneck slowing down releases. Alo Yoga cut QA cycles from five days to two hours. Vuori hit 50% automation in a single day, surpassing six months of Playwright coverage. HelloFresh caught 30+ critical bugs in month one, retaining $1.5M in revenue. Also trusted by Abercrombie & Fitch, DocuSign, Nextdoor and more.
