Getting Started

Getting Started with HarnessLaunch

HarnessLaunch takes you from a fresh Windows machine to a running DeepSeek Harness in a few minutes, and you never have to touch the command line. This guide covers what you need before you install, how your first launch works, and where to go next.

Before you begin

  • Windows 10 or 11, 64-bit
  • Roughly 500 MB of free disk space
  • An internet connection for the first setup
  • A purchased copy of HarnessLaunch. There’s no account and no activation.

Your first launch

  1. Buy HarnessLaunch on the Pricing page. It costs $4.57, one-time. You get the download link by email.
  2. Unzip HarnessLaunch_Setup_v1.0.zip, then run HarnessLaunch_Setup_v1.0.exe and follow the prompts on screen.
  3. Open HarnessLaunch and press Run DeepSeek Harness.
  4. HarnessLaunch starts the local server and opens DeepSeek Harness in your browser once it’s ready.
  5. In DeepSeek Harness, open the project folder you want to work in, then describe the task.

That first run takes a bit longer, because HarnessLaunch has to prepare the DeepSeek Harness package. After that, launches are quicker.

Next steps

Once you’ve done a first run, continue with Using HarnessLaunch for everyday use, or read DeepSeek Harness to see how the agent works with your codebase.
