Loadster Synthetic Monitoring runs recurring scripted checks for websites, web applications, and APIs. It supports Protocol Bots for HTTP/API monitoring, headless Chrome Browser Bots for browser flows, and Playwright Test scripts. Teams can monitor from eight locations or use self-hosted monitoring engines, with response-time and cycle-duration thresholds for ongoing checks. It is suited to engineering and operations teams that need synthetic coverage across API and browser journeys rather than basic uptime checks alone.

Pricing starts at $29 per month for Monitoring plans, which include thousands of fuel-free monitoring cycles each month plus SMS and phone notifications. Paid fuel tiers range from 1K Fuel at $77 per month to 20K Fuel at $797 per month, with unused fuel rolling over while subscribed. Pay-as-you-go options range from $97 per 1,000 units to $697 per 10,000 units, and that fuel does not expire. This structure can suit teams with predictable monitoring demand or occasional capacity needs, but the lack of a free plan and multiple fuel options make budgeting less straightforward.

The monitoring workflow goes beyond pass-or-fail checks. Loadster records uptime history and performance metrics, captures screenshots and request/response details, and provides diagnostic traces. Failed checks can create incidents and support automatic resolution, while notification policies connect with email, SMS, phone calls, Slack, PagerDuty, Opsgenie, VictorOps, and webhooks. Choose Loadster when scripted API and browser coverage, location flexibility, and incident workflows matter. Teams seeking a free starting tier or simpler flat usage pricing should consider an alternative.
