UptimeRobot
Pros
- + Best free tier in the category for non-commercial use: 50 monitors at 5-minute intervals, no credit card
- + Broad monitor coverage: HTTP, ping, port, keyword, API, UDP, DNS, SSL/domain expiry with confirmation re-checks
- + Four probe regions (NA/EU/Asia/Australia) with per-region thresholds and multi-region status tracking on paid plans
- + Published monitoring IP allow-list (IPv4 + IPv6) with a live API endpoint — firewall onboarding made simple
- + Status pages at every tier; white-label, own-domain, translated pages on Team and above
Cons
- - Free plan restricted to personal, non-commercial use since October 2024 — off the table for revenue sites
- - Slack/webhooks/PagerDuty integrations wait until Team ($39/mo annual); Solo users pay triple for a Slack alert
- - Pricing churn: 2025 restructuring plus monitor-count sliders, $15/mo extra seats and SMS credits make totals hard to predict
- - Interval speed is tier-bound (5 min / 60s / 30s / 15s) and there is no public SLA outside Enterprise
- - No built-in incident management (escalation, on-call); ownership marked acquired by third-party records without a published buyer
Checkly
Pros
- + True monitoring as code: TypeScript + Playwright checks versioned in your repo and deployed via CLI
- + Useful free Hobby tier and clear published plan pricing
- + 22 global check locations plus private locations for internal services on Team+
- + Full check types (HTTP, TCP, DNS, ICMP, SSL/TLS, gRPC, traceroute, heartbeat) with rich alerting and status pages
- + Local test mode in CI catches broken checks before deploy; SOC 2 since 2022
Cons
- - Usage-based billing scales with frequency x locations x checks — overage at $4 per 1,000 runs adds up
- - Developer-only tool: no point-and-click path for non-technical teams
- - Synthetic monitoring only — not a replacement for APM, logs, or metrics platforms
- - No public uptime SLA for the platform itself; best features (1-second checks, parallel scheduling) gated to Enterprise
