In their own words
LoadFocus
LoadFocus is a cloud platform for load testing, website page-speed testing, API monitoring and front-end UI testing. Load tests can use JMeter.jmx files or k6 JavaScript scripts; users can also describe a test in plain English and have the service generate a script in either format. The maker says a test can scale to more than 20,000 virtual concurrent users. Charts report response time, latency, hits and throughput per second, standard deviation, and the 50th, 90th and 99th percentiles. A Chrome extension and Jenkins CI plugin support creating or scheduling tests and checking results, while direct reporting integrations are listed for Datadog and Azure Application Insights. Customers can choose EU or US data storage regions. LoadFocus has free plans for API monitoring and load testing, and a 7-day trial is listed. Paid plans start at $19/mo. Plan test-run limits apply: users who reach an allowance must upgrade to unlock more runs. The maker presents it for engineering teams, including developers, web agencies, product owners and DevOps engineers.
Loadster Synthetic Monitoring
Loadster Synthetic Monitoring runs scheduled scripted checks against websites, web apps, and APIs from outside a user’s infrastructure. A monitor 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. Check schedules range from every minute to every day.
The product page lists eight dedicated monitoring locations across five continents, and one monitor can use several locations. Browser Bot and Playwright checks automatically collect TTFB, FCP, LCP, and CLS timing metrics. Monitoring cycles retain logs and detailed traces; browser checks include screenshots, while Protocol Bot checks capture request and response details. Alerts can go through email, SMS, phone calls, webhooks, Slack, PagerDuty, Opsgenie, and VictorOps. By default, one failed cycle opens an incident and one passing cycle resolves it, though the failure threshold can be raised. Hosted status pages can share selected status and uptime history privately or publicly, with custom domains when the customer controls DNS. Monitors can also run from a self-hosted Loadster Engine.
