# Webalert

A website and uptime monitoring service that checks websites, APIs, SSL certificates, DNS, and cron jobs and alerts teams via email, Slack, or SMS when downtime occurs.

**Route:** surfaced by the Web Application and Frontend Hosting Platform lane's de-branded queries → dependency to vercel.com.

**Why it's on the map:** The anchor Vercel is listed among the services Webalert tracks and can alert on; Webalert monitors Vercel-hosted sites but does not compete with, substitute, or integrate with the Vercel platform itself—the anchor relies on Webalert's monitoring capability to maintain reliability of applications built on it.

**Receipts** (verbatim from its page this run):

> Monitor websites, APIs, SSL certificates, DNS, and cron jobs

> Get instant alerts via email, Slack, and SMS on paid plans when downtime happens
