A really top of the notch customer support. I lost my GitHub account so the login into my vast ai account. I contacted the support and they where able to refund me my money.

The customer service is great! Bach is fantastically technically competent, to the point that they took a problem that I thought was super complicated and dissolved the whole thing by trying it straightforwardly. They have excellent problem solving and debugging skills, and were a tremendous help. I'm going to spend a bunch of money on vast.ai because of them! It's been fun setting stuff up with them. You won't have root access to the containers, but their Docker containers and their marketplace have been sufficient to get me good remote desktop into a GPU-heavy CAD application at the cheapest price anywhere!

Vast.ai is one of the most useful vendors I've used. Both in corporate and small business. They are responsive, knowledgeable, and helpful. As the market shifts to decentralized clouds and consumer hardware, Vast.ai will far exceed its competitors. Great support team!

Response from Vast.aiMar 23, 2026
Thanks for the honest feedback — we're glad you're giving us a shot, and we want to help make the experience less hair-pulling. You're touching on something real: as a marketplace, host machine quality does vary. The cheapest listings aren't always the best value if they cost you time troubleshooting. A few tips that can save you a lot of frustration: • Filter by machine reliability score — this helps you avoid the problem hosts quickly. • Look at verified or data center machines with higher ratings from other renters. • On-demand instances tend to be more stable than interruptible ones for getting up and running fast. The learning curve on picking good instances is real, but once you know what to filter for, the experience gets much smoother. If you run into issues again, don't hesitate to reach out to [email protected] — we're happy to help point you in the right direction. Hope your next run goes better!

I encountered a connection issue with a machine. The customer service replied to me in a few minutes. It turned out that the connection issue is due to my network side. I am well-satisfied with the conclusion in short.
