HarnessLaunch 1.0 for Windows
$4.57
One-time payment. No subscription.
- Launch DeepSeek Harness with one click

- Built-in update for the DeepSeek Harness package
- Clean uninstall of HarnessLaunch and DeepSeek Harness

What is not included
Updates to HarnessLaunch itself are not included. You buy version 1.0, and version 1.0 is what you keep. If we release a later version, it will be a separate purchase.
We would rather say this plainly on the pricing page than have you find out later. What you get for $4.57 is the version described above, working, for as long as your Windows machine runs it.
Your download link does not expire
You can download version 1.0 again whenever you need it: a new computer, a lost file, a reinstall. The link stays valid.
14-day money-back guarantee
If HarnessLaunch doesn’t work on your machine, write to us within 14 days and we’ll refund you in full. No explanation needed.
Why there is no subscription
HarnessLaunch is a launcher, not a service. You install it once and it does its job. A monthly fee would only be fair if something ran for you every month. Nothing does.
How you get it
Right after payment you get an email with your personal download link. No account, no activation code, no waiting. Keep that email: the link stays valid, so you can download version 1.0 again at any time.
Questions about pricing
Is DeepSeek Harness itself included?
HarnessLaunch installs and manages DeepSeek Harness for you. DeepSeek Harness is open-source software by DeepSeek AI. Usage costs for the AI model itself are billed by your model provider, not by us.
Are updates included?
No. Your purchase covers HarnessLaunch 1.0. If we release a later version, it will be a separate purchase.
What about the Update button in the app?
That’s a different thing. The Update action inside HarnessLaunch updates the DeepSeek Harness package. That part is included and works as described. The note above is only about future versions of HarnessLaunch itself.
Do I need a licence key?
No. You get a personal download link by email. There’s nothing to activate.
Can I use it at work?
Yes. Commercial use is included. The licence covers one person on one computer.
What if it does not work on my machine?
Write to us within 14 days and we’ll refund you in full.
Is this an official DeepSeek product?
No. HarnessLaunch is an independent launcher for DeepSeek Harness. It is not affiliated with or endorsed by DeepSeek AI.
