BlazeMeter от 58WIN

The BlazeMeter Firefox 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 Firefox 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 Firefox browser.
By using JMeter locally, you can debug and enhance the JMX file created by the Firefox Extension to ensure your script is ready to go.
