FetchPing

FetchPing watches your sites, APIs, servers, and cron jobs around the clock, with checks running as often as every 30 seconds from multiple regions so a single local blip never sends you a false alarm. It supports seven monitor types, including HTTP and HTTPS endpoints, raw TCP ports, ICMP ping, DNS resolution, SSL certificates, domain expiry, and heartbeat checks for scheduled jobs. You can also stand up public status pages with incident timelines, invite your team to share monitors and alert channels under one account, and schedule maintenance windows so planned downtime never triggers an alert. The newest addition is server agents, which install directly on your own machines to report CPU, memory, disk usage, and load average. There's a free plan to start with no credit card needed, and a Pro plan once you need more monitors, faster checks, and longer history.
