About AlertKite
AlertKite is built and run by Ali Ammar, an independent developer in Pakistan. There is no large team behind it: the person who builds the checks also answers the email.
What it does
AlertKite watches websites, APIs, SSL certificates, domains and scheduled jobs, and tells you on Telegram, Slack, Teams, Discord or email when something is wrong. A failure is confirmed twice before any alert goes out, so an alert arriving means something is genuinely wrong.
Where others are the better choice
AlertKite is a young product that checks from one region, with a second check confirming a failure. Tools like UptimeRobot have been running since 2010 and check from several regions. The comparison pages say where each one wins.
