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.
Locust
Locust is an open-source performance and load testing tool for HTTP and other protocols. Test scenarios are written in Python, with regular Python libraries available for use within them. Tests can run from the command line or web interface, which displays throughput, response times, and errors in real time; results can be exported for later analysis. The interface shows progress and lets users change load during a run. Locust can distribute tests across multiple machines and says it can support hundreds of thousands of concurrent users. Other systems and protocols can be tested by adding a client, and documentation lists community extensions for protocols and reporting. Optional OpenTelemetry support exports traces, metrics, and logs to compatible backends such as OTLP, Prometheus, Jaeger, and Tempo. Automatic instrumentation currently covers the requests library. Installation is documented with pip install locust or uvx. Locust is free and MIT-licensed. Its documentation also describes hosted load testing through Azure Load Testing, with reporting, Application Insights integration, and CI/CD support for Azure DevOps and GitHub Actions.
