BlazeMeter | The Continuous Testing Platform

Record Selenium and HTTP traffic to create a load and functional tests in less than 10 minutes (Apache JMeter Compatible). The BlazeMeter Chrome extension enables you to - Record. Upload. Run. The Chrome extension records all HTTP/S requests and actual user interactions that your browser sends. It creates a JMeter or Selenium script, and automatically uploads it to BlazeMeter.com, where you can execute tests with a single click. No need to install JMeter nor Selenium to record or run GUI Functional, API Functional, or Performance tests, the Chrome extension will create the JMeter (JMX) and Taurus Selenium (YAML) scripts automatically. The extension will also allow you to debug and test your recorded Selenium session on your local Chrome browser. By using JMeter locally, you can debug and enhance the JMX file created by the Chrome Extension to ensure your script is ready to go.
