The Load Impact Session Recorder – Now Available as a Chrome Extension!

Start a load test with just a few clicks. Record all HTTP traffic and use the recordings to simulate real user traffic under realistic load.

The Load Impact Chrome extension will capture everything – every single thing being loaded into the browser as you click – including ads, images, documents, etc., so you get a far more accurate read of what’s going on.

Just press “record”, start browsing and when complete, the script will automatically upload to your Load Impact account.

Here’s how it works:


With the help of our Chrome extension, you can run up to 10 different users scenarios in each load test and simulate up to 1.2 million concurrent users.  You can also run the multiple user scenarios simultaneously from up to 10 different geographic regions in a single test (powered by Amazon and Rackspace).

Until now our session recorder required developers to go to our website and manually change the proxy settings in the browser or operating system to perform a recording. That was a bit of a hassle, and the proxy solution sometimes caused problems with SSL certificates.

The extension now automates the entire process, from recording traffic in a specific browser tab, to stopping, saving and sending the scrip to your Load Impact account for future use.

The Chrome extension is available free of charge from the Google Chrome Web Store and is easily ported to the Safari and Opera browsers.  An extension for the Firefox browser is planned for release early next year.

To use the Chrome extension, you will need to register for a Load Impact account at

    I have one issue.

    I log in into LOADIMPACT.COM using. Let say: and password.
    I logged in successfully.Now i want to record a scenario.For that i installed chrome recorder .
    Now it asks me Token id. I generate one token id from Accounts section in LOAD IMPACT.
    and entered in chrome recorder.
    I was able to generate script through recording and also i am able to perform all others operatioins.

    Now i have different login credentials. lets say and password on the same system.
    Now if i perform recording it will record but when i try to import it to load runner it loads in the previous account. ie
    As u i have entered the token id from previous account.

  3. Need Suggestions.
