Velprove tells you whether your web app actually works, not just whether the server returned a 200. It opens a real browser, signs in like a user, and catches the outages pings miss: broken logins, failed checkouts, empty 200s. Run browser login, API, multi-step, and HTTP monitors from 5 global regions, with alerts to Slack, PagerDuty, and more. Free plan, no credit card required.
