Commercial use on every plan
UptimeRobot changed their free plan to "personal, non-commercial use only" in late 2024. If you're monitoring production systems or client sites, you need a paid plan — or you need to switch.
watch4.me allows commercial use on every plan, including free. Monitor your SaaS, your clients' sites, your agency portfolio. No restrictions, no gotchas.
All alert channels free
Most competitors restrict Slack, Discord, and webhook alerts to paid plans. We include Email, Slack, Discord, Telegram, and webhooks on every plan — because it costs us nothing to deliver a Slack message, so why charge you for it?
Plus 120+ additional services via custom Apprise URLs — Pushover, ntfy, Gotify, Matrix, and more.
6 monitor types — all free
UptimeRobot gives you HTTP, keyword, and ping. Better Stack gives you HTTP and heartbeat. We give you HTTP, SSL, DNS, TCP, Heartbeat, and Domain Expiry — on every plan.
SSL certificate monitoring alone is a paid feature elsewhere. We include it free because monitoring your cert shouldn't require a credit card.
No false positives — even on free
When a check fails, we automatically re-test from an independent probe in a different geographic location before creating an incident. Most competitors retry from the same location — or don't retry at all. Our two-probe verification means every alert you receive is a real, confirmed problem. This isn't a paid feature. Every plan gets it.
