As answered by people managing HetrixTools and PingWise.
PingWise's answer:
A site is marked down only when two thirds of 15 probes agree, from at least three continents and three networks, two rounds in a row. One city's bad route never pages anyone, and every alert shows what each probe saw. Pricing is per check: 650,000 free credits a month, then prepaid packs from €5, with no seats or tiers.
PingWise's answer:
Fewer false alarms and a smaller bill. Most monitors alert when one or two locations fail; PingWise confirms across continents first, and confirmation re-checks are free. Status pages, team members, all alert channels and the API are included in every account instead of being sold as plan add-ons. Switching is easy: import from UptimeRobot, updown.io, Uptime Kuma or CSV, and optionally run both side by side for 14 days to compare their alerts with ours.
PingWise's answer:
Web agencies, hosting providers, MSPs and small dev and ops teams who watch many sites and are tired of being woken by alerts that turn out to be false. Also freelancers and side projects that fit in the free 650,000 credits a month.
PingWise's answer:
PingWise was built by Hostbox, a hosting provider in Greece. Uptime monitoring always felt overpriced: watch many sites every minute and you end up on a big plan tier, paying for seats and extras on top. So PingWise charges per check instead: 650,000 free credits a month, then prepaid packs from €5, with status pages, team members and every alert channel included. It also waits until probes on three continents agree before calling a site down. It started as the monitoring for Hostbox's customer sites and opened to everyone in October 2026.
PingWise's answer:
Python and Django for the central service, PostgreSQL for data, and a dependency-free Python agent on 15 dedicated servers at 5 providers.
