Comparison
Developer-focused synthetic monitoring vs simple uptime monitoring. Here's how they compare.
Checkly treats monitoring as code. You write JavaScript/TypeScript checks, store them in git, and deploy via CLI. It's built for developers who want Playwright-based E2E checks running in production.
UptimeRobot is point-and-click. Add a URL, set an interval, get alerts. No code required. It's simpler but less powerful for complex scenarios.
Checkly is great for teams that need E2E browser testing and monitoring-as-code in their CI/CD pipeline. But at $30+/month, it's overkill if you just need uptime checks.
UptimeRobot is simpler and cheaper, but caps you at 50 monitors on the free tier and limits paid plans to per-monitor pricing.
For straightforward uptime monitoring without monitor caps, UptimeSignal gives you unlimited monitors for $15/month — with a modern interface, status pages, and no commercial-use restrictions on the free tier.
UptimeSignal: 25 monitors free, unlimited for $15/month.
No per-monitor pricing. No code required. Status pages included.
