Competitor details as of September 2026, taken from each vendor's own pricing page.

Nanokoi combines uptime monitoring, SSL certificate checks, DNS monitoring and Google Lighthouse performance tracking with Core Web Vitals. The free plan monitors up to 5 URLs every 5 minutes, with no credit card required. Starter ($10/month) adds 1-minute checks for 10 URLs; Professional ($29/month) adds 30-second checks, AI-powered performance insights and public SLA status pages for 50 URLs; Enterprise ($99/month) covers 200 URLs with custom check intervals, custom integrations and white-label options.
If you mainly need basic availability checks for lots of URLs, UptimeRobot's free plan has a bigger monitor allowance. Its paid tiers unlock faster checks and additional monitor types.
Pingdom pairs synthetic checks with real user monitoring and sits within the SolarWinds observability suite, which suits teams already using SolarWinds tools.
Better Stack bundles uptime monitoring with incident management and log management, a good match for engineering teams that want incident workflows in the same tool.
It depends on what you need to monitor. If you want uptime, SSL, DNS and Lighthouse performance data in one place, Nanokoi covers all of them, starting with a free plan for up to 5 URLs and paid plans from $10/month. If you only need basic uptime checks for many URLs, a free tier with a larger monitor allowance may suit you better.
UptimeRobot's free plan allows more monitors (50 at 5-minute intervals, as of September 2026). Nanokoi's free plan covers up to 5 URLs at 5-minute intervals and adds Lighthouse performance monitoring, Core Web Vitals tracking, DNS monitoring and SSL certificate monitoring to the same dashboard.
As of September 2026, Nanokoi, UptimeRobot, StatusCake and Better Stack offer free plans. Pingdom offers a 30-day free trial, and Uptime.com offers a 30-day money-back guarantee instead of a free tier.
Free plans typically check every 5 minutes. Nanokoi Starter checks every minute, Professional every 30 seconds and Enterprise supports custom intervals. Competitors offer similar steps on their paid tiers; see the comparison table for details.
Every service here will tell you when your site goes down. The differences are in free-plan limits, check intervals and what else gets monitored. If you want availability, SSL, DNS and Lighthouse performance data in a single website monitoring dashboard, Nanokoi is built for that.
