SutramX is the uptime monitor that tells you why. It monitors websites, APIs, cron jobs and MCP servers, and every alert says what failed, where, and whether the cause looks like yours, a vendor's or the network's. Paid plans confirm an outage from more than one location before paging anyone. Alerts go to email, Slack, Teams, Discord, Telegram, WhatsApp, SMS and more. Status pages included, unlimited team seats on every plan.
