What's WebSurge?

West Wind WebSurge is a Windows application that helps you to easily capture and play back URL requests, either individually for easy application, service and API testing scenarios, or under heavy load for stress testing scenarios. WebSurge makes it easy to save, share and reuse URL sessions you have created, so you can easily start up sessions again on your own or somebody else's machine.

Here's what the stress testing output looks like:

Web Stress Testing

The goal of this tool is to make it drop dead easy to capture or create HTTP request content and test and play it back easily under load. It provides simple results that are easy to understand and act on. It's so easy that you can frequently stress test Web applications for load characteristics during development, testing and in production.

  • Easy capture or manual entry of URLs
  • Interactive recording of screen sessions
  • Quickly access and run your test
  • Test and preview individual URLs
  • Immediate process feedback

Interactive URL Testing

WebSurge is great for load testing, but it's also an excellent URL test tool for developers who need to test API, SOAP or any other type of HTTP application service. You can easily capture sessions and easily recall individual URLs for testing of endpoints. The formatted output views make it easy to visualize the resulting contact with syntax highlighted markup/text as well as a preview for HTML content. We've optimized the UI flow to make request access and tests as easy as possible. If you've used tools like PostMan or Fiddler to for these tasks, check out WebSurge for creating savable and shareable sessions that you can easily test repeatably. Sessions are stored in plain files and can easily be shared in source control, the file system, or via cloud storage solutions like DropBox or OneDrive. And because it's just text it's easy to modify Sessions in raw form or generate them via code.

And here is a screen shot that demonstrates simple URL testing or reviewing of individual request output from a test run.
