## Key **differences**

**OnlineOrNot** focuses on uptime, API monitoring, and status pages for software teams. **Testomato** goes deeper into website monitoring with faster 15-second checks, automated form testing, meta tag tracking, and content verification — catching issues that simple uptime tools miss — and includes public status pages as well.

## Why choose **Testomato** over OnlineOrNot

- #### 15-second uptime checks

  Detect downtime 2x faster than OnlineOrNot's 30-second monitoring interval on the Pro plan.

- #### Form testing

  Automatically test that login forms, contact forms, and checkout flows work correctly — with simple no-code rules instead of Playwright scripts.

- #### Meta tags monitoring

  Track title tags, meta descriptions, and Open Graph data to protect your SEO and social sharing.

- #### Deep content verification

  Verify that pages display correct content, prices, and information — not just that they return HTTP 200.

- #### Zero-config setup

  Add your URL and Testomato auto-discovers pages and sets up checks instantly. No scripts or manual configuration needed.

- #### More monitoring locations

  Monitor from 9 worldwide locations compared to OnlineOrNot's 6 regions for broader geographic coverage.
