Pingbuddy

A site can return HTTP 200 while visitors see a blank screen. Pingbuddy opens your public URL in a real browser to catch rendering failures, JavaScript errors and on-page error messages. When an outage is confirmed, it alerts you by Telegram or email. A screenshot shows what visitors saw, an AI explanation suggests a likely cause, and a fix prompt gives you a starting point in Lovable, Bolt, Cursor or v0. Pingbuddy also tells you when the site recovers. The free plan covers up to 20 sites, with uptime checks every five minutes and browser checks every 30 minutes. It includes screenshots and AI explanations for up to 10 outages a month.
