Find the Right Plan for Your Needs

WebPageTest Pro our premium, paid subscription plan that unlocks powerful functionality and features for WebPageTest including, but not limited to: bulk testing, premium testing locations, high priority in testing queues, the WebPageTest API, experiments, dedicated support and private tests.

WebPageTest Starter is our free plan available to all users to run WebPageTest runs that provide all the performance metrics that WebPageTest has provided for years plus access to the new Opportunities report.

Both WebPageTest Starter and Pro give you access to save your Test History for 13 months.

FOR ALL PLANS, A test on WebPageTest is comprised of one or more test runs. A test run is defined as a single page load within a test. Here are a few examples:

- A test from a single browser and location, with 3 test runs, first view only, counts as three test runs. (3 runs * 1 load per run)
- A test from a single browser and location, with 5 test runs, first and repeat views for each run, counts as 10 test runs (5 runs * 2 loads per run)
- A test from a single browser and location, with 4 tests runs, first and repeat views for each run, and an additional Lighthouse run, counts as 9 test runs ( (4 runs * 2 loads per run) + 1 Lighthouse run)
- An experiment from a single browser and location, with 2 test runs, first view only for each run, counts as 4 runs (2 runs * 2 tests (one for the experiment, one for the control run).

WebPageTest Starter gives you access to 30 locations worldwide, including mainland China. With WebPageTest Pro, you get access to 10 more premium locations.

WebPageTest is always up-to-date on the current version of every browser and you can test on Chrome (stable, beta, canary), Firefox (stable, beta, ESR), Microsoft Edge (dev) and Brave.

WebPageTest Pro also supports mobile emulation testing. You can test mobile content by emulating an Android browser by passing “mobile=1” as an API option.

Opportunities and Experiments are a powerful combination that will let you quickly identify areas of improvement for your website and test the impact of any relevant optimizations without ever having to write a line of code.

Opportunities are recommendations that are broken down into three categories:
- Quickness
- Usability
- Resilience

Opportunities are a free feature of WebPageTest provided to all users.

For every opportunity, you will be presented with some combination of tips (suggestions for what to do to improve) and experiments (the ability to apply optimizations right within the WebPageTest sandbox). When you choose to run an experiment, WebPageTest applies the optimization in our sandbox environment and then runs a test (alongside a control test which uses our sandbox environment without applying the optimization), and presents you with results showing you how significant, or insignificant, the improvement was.

Experiments are a paid feature and are only available to WebPageTest Pro subscribers.

We provide 1 free experiment per test for you to check out WebPageTest Experiments. You can also run Experiments from our in-house webpage called The Metric Times where we have built in anti-patterns for easy testing.

We do not have a free trial option apart from the above 2 options, since Web PageTest Pro gives you all the metrics (except for the option to run the experiments) you see on a typical WebPageTest test result page as well as in the JSON today for any test you run on www.webpagetest.org.
