UptimeRobot is one of the most popular uptime monitors — reliable ping-based checks, a generous free tier, and hundreds of integrations. If a server going offline is your only concern, it's hard to beat.
For agencies and freelancers managing client sites, server downtime is rarely the top risk. The more common failure modes are an SSL cert quietly expiring, a domain lapsing on auto-renewal, or a DNS record changing unexpectedly. IT Watch monitors all four check types in one place — not just whether the server answers.
Best-in-class uptime monitoring. Excellent free tier with up to 50 ping monitors. Wide integrations, status pages, and on-call scheduling.
All four check types (SSL + domain + uptime + DNS) in one dashboard. The 30/14/7/3/1-day alert ladder gives agencies advance warning on expiry deadlines. Built for the agency/freelancer workflow, not infrastructure ops teams.
