UptimeRobot vs Pingdom

From €9 per month (Solo, billed annually; €10 monthly)

From $18 per month (10 uptime checks, 1 advanced check, 50 SMS; $16.50 annual)

One of the best free tiers in infrastructure tooling, and paid plans are still inexpensive: Solo €9, Team €35 and Scale €65 a month on annual billing. Solo buys the 60-second interval.

Priced by a calculator rather than named tiers: 50 uptime checks run about $78/month and 100 about $149, so the per-check rate falls slowly with volume. Transaction checks and Real User Monitoring are priced separately from basic uptime checks and add up.

50 monitors at 5-minute intervals, free forever, with SSL and domain-expiry checks and one status page.

• Free tier covers what most small projects actually need.
• Five-minute setup with no configuration to learn.
• Status pages included even on lower tiers.

• Very large global probe network with a long operating history.
• Simple to set up for basic availability monitoring.
• Combines synthetic checks with real-user monitoring.

• No browser-based transaction monitoring — availability only.
• Basic alerting logic; expect some noise from transient failures.
• Limited reporting and no observability integration.

• Feature development has been slow under SolarWinds ownership.
• Transaction-check authoring is dated compared to code-first alternatives.
• Pricing is no longer competitive against newer entrants.

Side projects, small businesses and anyone who currently has no monitoring at all.
