How this works: every two weeks we ask ChatGPT, Gemini and Claude each question below through their official APIs, without web search, and record which products each answer names and in what order. The share is how many of the latest answers name a product. This is a record of what AI says, not our recommendation. Makers can ask to be left out at hello@citemark.io.

Here are alternatives to UptimeRobot, grouped by type and with notes on what each is best for. If you tell me your budget, scale, or must-have features (API, SMS/pager alerts, status pages, RUM, checks from specific regions), I can narrow this to the best few options.
General website/HTTP uptime monitors
Pingdom (SolarWinds) — well-known, synthetic checks, RUM, good reporting and alerts; paid tiers but feature-rich for SMBs and enterprises.
StatusCake — inexpensive, many check types, global locations, free tier with limitations.
Uptime.com — enterprise-focused synthetic monitoring, detailed incident management, status pages and API.
Site24x7 (Zoho) — broad monitoring (servers, apps, networks) with synthetic, RUM and APM features.
Checkly — JS-based browser and API checks, Playwright support, CI-friendly, good for testing complex flows.
Cronitor — uptime, cron/job monitoring, real-time alerts, good for background jobs and scheduled tasks.
Healthchecks.io — great for heartbeat/cron monitoring; simple and inexpensive.
HetrixTools — API checks, blacklist and domain tools, affordable.
Incident management / escalation-centric
Better Uptime — combines uptime checks + incident management + phone/SMS/pager escalation + status pages; modern UI and on-call features.
PagerDuty / VictorOps (Splunk On-Call) — not pure uptime monitors but excellent for advanced incident routing/escalation; pair with synthetic checks from other services.
All-in-one observability suites (larger budgets)
Datadog — synthetic monitoring, RUM, APM, logs; strong for teams that want full observability.
New Relic — Synthetics, APM, RUM, good integrations and dashboards.
Grafana Cloud — synthetic/heartbeat checks plus logs/metrics/traces if you want an integrated stack.
Simple/cheap/free options
Freshping (Freshworks) — free tier with multiple monitors, basic alerts, good for small sites.
Montastic — very simple, free/cheap site checks.
Upptime (GitHub Actions + status page) — open-source; uses GitHub Actions for checks and GitHub Pages for a status page — very inexpensive if you can self-manage.
Other useful tools/features to consider
Status pages: Better Uptime, Statuspage (Atlassian), Cachet (self-hosted), Upptime.
If you want a drop-in UptimeRobot replacement with more on-call features: Better Uptime.
If you need enterprise observability with synthetic + RUM + APM: Datadog or New Relic.
If you want low-cost developer/API-focused checks: Updown.io, Checkly, or Cronitor.
If you want free/simple monitoring and a status page you control: Upptime (open-source) or Freshping.
