QA agent for vibecoded apps. Real browser checks, your AI fixes them. Ship to green.
Run Val, the QA agent for vibecoded apps, on every PR. Val drives a real browser against your preview URL, catches broken links, dead buttons, busted layouts, accessibility violations, and posts a report as a PR comment.
Val is a paid product. Get a license key at val.nyx-intelligence.com, store it as a repository secret (e.g. VAL_LICENSE_KEY), and pass it to the action.
