What it does
Dotcom-Monitor is a hosted synthetic monitoring platform for websites, APIs, web applications, infrastructure, and browser-driven user journeys. Its checks can simulate multi-step interactions, validate API responses, and run from monitoring locations outside the service being tested. Alerts and reports provide evidence such as snapshots and waterfall data for investigation; teams still diagnose and repair the underlying issue.
Match each check to the failure you want to catch
Dotcom-Monitor supports external website and uptime checks, authenticated API monitoring, and real-browser tests for user journeys such as logins and checkouts. API checks can validate responses and use Postman collections; browser checks help identify failures that a simple availability probe may miss. Monitoring from external locations gives teams another view of how a service behaves for users.
Alerts and reporting include diagnostic details such as snapshots and waterfall data, which can help an engineer investigate a failed request or slow page. The service detects and documents symptoms rather than fixing the application. The pricing page lists a free plan with up to 25 targets, five-minute checks, two locations, and email alerts; paid pricing depends on the selected platform, target count, and frequency. The free-plan retention figures conflict: the visible card/table says 21 days, while embedded offer metadata says 7, so confirm retention before relying on it.
Strengths
- Real-browser checks can exercise multi-step journeys such as logins and checkouts, beyond simple uptime checks.
- API monitoring supports authenticated requests and response validation, including Postman collections.
- External locations and diagnostic snapshots or waterfall reports help teams investigate failures.
Watch out for
- The free plan is limited to 25 targets, five-minute checks, two locations, and email alerts.
Best for
- Checking user-visible website journeys and service availability from external locations
- Monitoring APIs and validating responses without running a full browser flow
- Teams that want synthetic-check alerts and diagnostics alongside uptime detection
