help Loader.io FAQ

Is Loader.io a JavaScript library or a web load-testing service?

Loader.io is a cloud-based load-testing service for websites and APIs, not primarily a JavaScript library for deferring tracking scripts. It can simulate thousands of concurrent connections and display results during a test.

How do I verify a website before testing it with Loader.io?

You first add the target hostname in Loader.io and complete the verification step using the method provided by the service. Each hostname, such as a separate subdomain, must be registered as its own target host.

What kinds of load tests can Loader.io run?

Loader.io supports tests based on total clients, clients per second, and maintaining a client load. Those modes let you model a burst of traffic, a steady arrival rate, or a sustained number of connections.

Can Loader.io test an API as well as a normal website?

Yes, Loader.io is designed to test web applications and APIs by sending requests to a target host. The service also provides an API for creating and managing tests programmatically.
