  • Do you know how much load your website can take concurrently?

    Check out with these tools to perform a load test on your site.

    Knowing your website capacity is essential for your online business. The fact is we put a lot of effort into designing, securing & SEO but often forget to know how many concurrent users can be served without compromising the website performance.

    The following tools will help you to find out some hits your website can take before it dies or degrades the performance.


    LoadView lets you start stress-testing your site for free, by giving away $20 in credits you can use for on-demand testing. This amount allows for a couple of tests with default parameters. If you like the service, you can keep using it on-demand, paying for each test, or signing for a monthly or annual subscription. Prices of the subscription plans range from $199 per month to $1499 per month.

    All plans include ten geographical zones, 180-day data retention, dedicated load injectors, Amazon and Google Cloud support, and load test behind the firewall. Some unique features differentiate LoadView from other stress-testing platforms; for example, testing with real browsers and providing enterprise-level testing and world-class 24/7 tech support.

    You get three load test curves into a single platform.

    • Load step
    • Goal-based
    • Dynamic

    And, with the help of EveryStep web recorder, you can build complex scripts in minutes which you can run against more than 40 desktop and mobile browsers. You can use LoadView to run a stress test on the website, complex web applications, API, or web services.

    Flood IO

    Flood IO is a cloud-based performance testing service where you can upload your JMeter, Selenium test plan, or build your test using their GUI.

    The good thing about Flood is you can generate load tests with unlimited concurrent users in a free plan with few limitations.

    Considering unlimited concurrent users, you can use Flood not just for website performance testing but many others like DNS load, API, etc.

    You get a real-time timeline of load test with concurrent users, response time, network throughput, latency, transaction metrics.



    Loader lets you run a load test for one minute with 1000 user requests in the free account. Not bad to run against 1000 users in free.

    Loader.io offers an option to configure a number of requests, error threshold for a timeout, request method like GET/POST, Protocol like HTTP/HTTPS, Headers, Body Parameters & response variables.


    Load Storm


    With a free account, Load Storm allows you to stress test against your web application with ten users for 10 minutes.

    I know ten users are very less for load test, but if you are looking to see the test in action and understand the metrics, then it’s not bad at all.




    If you love Jmeter, you must try Blazemeter. Setting upload scenario properties is very easy and allows you to test from Ireland, Virginia, California, Singapore, Oregon, Sydney, Tokyo, and Sao Pulao.

    In the free account, you can perform load for up to 50 users and end of the test; you will get test summary, load report, monitoring, logs, errors, etc.


    Load Focus

    Perform the test with 500 concurrent users with a free account from either US or Ireland location. Load Focus also has an option to perform website speed test and monitoring.



    OctoPerf is a SaaS-based performance testing tool powered by JMeter for the web, API, REST & mobile app. You can design, monitor, execute, and analyze the website perform through a web browser.

    Each test comes with an option to download the beautiful report where you get the following.

    • Test/statistics/results summary
    • Hits rate and response time
    • Request details
    • Response time breakdown
    • Average response time
    • Throughput
    • Error details


    I hope the above online services help you to perform the load test on your web applications for better capacity planning. Alternatively, if you are looking to use JMeter and need some guidance then check out this video course.
