Load test your site to find its breaking point
Simulate thousands of users,
find performance bottlenecks.
Test from 15 cloud regions
or your own machines.
Your site has a breaking point.
It will crash under excessive load. When it crashes or bogs down, you'll lose business, drive away customers, and damage your brand.
The fact that crashes like these typically happen during high traffic events only makes them worse, because there are that many more people to disappoint and that much more business to lose out on.
So what if we could be a bit proactive, and mitigate the risk of downtime due to high traffic events? What if you could ensure your site will scale to handle any reasonable amount of traffic the world can throw at it?
Load testing your site will tell you its breaking point. By knowing the breaking point ahead of time, you can predict how it will scale to meet demand. Properly load and stress testing can reduce the risk of traffic-related site failure by 80-95%, and even a quick volley of load tests can reduce your risk by 30-50%.
Load Testing For Static Websites
If you've got a static site (or one powered by Wordpress or another CMS), Loadster gives you the tools you need to hit it with a lot of traffic. Install the Loadster Recorder browser extension and record your most common user journeys as Loadster scripts. Then, play them back with thousands of concurrent users from any of 15 cloud regions across the globe.
Loadster's cloud testing platform will save you time and money by spinning up fully managed instances across multiple regions, coordinating your load test across all of them, and spinning them down just as soon as the test is finished. You'll get meaningful, actionable results to tell you how well your site performs under heavy load. When the test finishes, optimize your site and run again!
Customers like you have used Loadster's on-demand cloud testing platform to successfully prepare for their site for major high traffic events such as Black Friday and the Super Bowl.
Load Testing For Dynamic Web Apps
Admittedly, testing dynamic web apps can be a little more complicated than static websites, but it's no less important. It's not enough to just slam your web app with a bunch of identical requests! You have to deal with stateful interactions, user sessions, form submissions, and so on. Properly load testing dynamic applications means simulating hundreds or thousands of different user sessions – each submitting their own request data and handling the server's response – in parallel.
With Loadster, you can bind dynamic datasets to your scripts, so that each virtual user supplies its own data and context. Binding to a dataset full of usernames and passwords will make each virtual user log in to your application with a different account, to fully exercise your app's data layer and data store. You'll avoid the pitfall of false optimism: thinking your web app performs fine, when you're really only leveraging a tiny slice of it.
All but the most trivial web applications will return a different response to certain requests, depending on who the user is and how they've interacted with the system previously. Use Loadster's validators and capturers to make sure the response coming back is what you expect, and extract values that you can use later in your script, to send additional requests.
Load Testing For Modern APIs
APIs are critical to the modern enterprise, as well as software teams of every size. It's also where you'll find the most exciting opportunities for load testing. We now use APIs to power anything from a small Single Page Application (SPA) to a large distributed system of microservices, and in either case, performance is critical.
Loadster's datasets, validators, and capturers work just as powerfully for API load testing as they do for dynamic web apps. And APIs can actually be a lot easier to work with, since their requests and responses tend to be clean JSON or XML or another format, instead of big messy web pages.
By working at the HTTP protocol level, you'll be able to hit any kind of HTTP API (REST, GraphQL, JSON-RPC, XML-RPC, etc) with as much load as you need to find the bottleneck.
If your API is documented in OpenAPI/Swagger, so much the better! Loadster's scripting interface can pull in the API specification so you can create your test scripts in record time.

Load testing from anywhere
Loadster is a cloud-hybrid load testing solution, with a browser-based dashboard to control everything. Generate load from 15 cloud regions or your own self-hosted engines. It's the best of both worlds and allows you to test both public and private sites.
Zero to 60,000 in 2-3 minutes (virtual users, that is)
Need to run a massive load test? No problem. Loadster can launch hundreds of fully managed cloud engines in minutes. Say goodbye to spinning up your own infrastructure for load testing, and the extra bills that came with it.
Peace of mind pricing
With Loadster, you'll pay a set monthly price, no matter how many tests you need to run. Our price includes cloud costs and everything, so it's easy to budget for performance with no unexpected surprises. Just tell us the upper limit of virtual users you want to simulate and we'll take care of the rest.
Get up to speed quickly
Your time is valuable, and Loadster helps you do more with it. Record your test scripts using the Chrome extension or Loadster's own recording proxy. Edit them with the intuitive graphical scripting interface, so you'll be getting valuable test results in record time.
