Loadster Synthetic Monitoring
Phoenix, Arizona, USA
What it is
Loadster Synthetic Monitoring runs scheduled scripted checks against websites, web apps, and APIs from outside a user's infrastructure. Monitors can check one page or endpoint or follow a multi-step journey such as logging in, navigating pages, and submitting a form. Scripts can use Browser Bots, Protocol Bots, or Playwright Test in JavaScript or TypeScript. Checks can run as often as every minute or as infrequently as daily, using eight dedicated locations across five continents; one monitor can use multiple locations. Each cycle retains logs and detailed traces, with screenshots for browser checks and request-response details for Protocol Bot checks. Browser Bot and Playwright checks automatically collect TTFB, FCP, LCP, and CLS metrics. Alerts can go to email, SMS, phone calls, webhooks, Slack, PagerDuty, Opsgenie, or VictorOps. Hosted status pages share selected status and uptime history privately or publicly, and can use custom domains when the customer controls DNS. Monitors can also run from a self-hosted Loadster Engine. The product has a free starter account with 50 units, not a monthly refill; paid options include $77 a month for 1,000 monthly units and pay-as-you-go units.
