Website downtime costs businesses an average of $5,600 per minute according to Gartner. Whether you run a personal blog or a growing SaaS, you need to know the moment your site goes down. The good news? Several excellent monitoring tools offer generous free tiers.
We tested and compared the most popular website monitoring tools available in 2025 so you can pick the right one for your needs.
What to Look for in a Free Monitoring Tool
Before diving into the list, here's what matters most when choosing a free uptime monitor:
- Number of monitors — How many URLs can you track on the free plan?
- Check interval — How often does the tool check your site? Every minute or every five?
- Alert speed — When your site goes down, how fast does the alert arrive?
- Incident history — Can you see past outages and their duration?
- Ease of setup — Can you start monitoring in under two minutes?
