Loadster Synthetic Monitoring
What Loadster Synthetic Monitoring is
Loadster Synthetic Monitoring runs scheduled checks of websites, web apps, and APIs from outside your infrastructure. You can create monitors with Browser Bots, Protocol Bots, or Playwright Test scripts in JavaScript or TypeScript. A script can check one page or endpoint, or follow a sequence such as logging in, navigating, and submitting a form. Checks can run as often as every minute or as rarely as once a day, using one or more of eight listed monitoring locations across five continents. Browser Bot and Playwright checks collect TTFB, FCP, LCP, and CLS metrics; cycles retain logs and traces, with screenshots for browser checks and request-response details for Protocol Bots. Alerts can use email, SMS, phone calls, webhooks, Slack, PagerDuty, Opsgenie, or VictorOps. Hosted status pages can share selected status and uptime history privately or publicly. For inaccessible sites or specific locations, monitors can run on a self-hosted Loadster Engine. Pricing is listed from $29/mo, with a free plan and free trial.
