Featured Reviews

Tanvir Siddique - PeerSpot reviewer
Technical Officer at ADN Telecom
Easily accesses open solutions with seamless compatibility for testing and development
The most valuable feature is the seamlessness. When I install a Linux operating system, I can use Windows applications through Oracle VM VirtualBox seamlessly. There are many applications that work only on Windows. For desktop testing purposes, I used Oracle VM VirtualBox, and it works fine. The guest OS compatibility was tremendous because I used Oracle VM VirtualBox on Linux and ran Windows applications on top of that, working seamlessly.

Dev Ops Engineer at a construction company with 11-50 employees
Intelligent autoscaling has cut compute costs and now manages ephemeral workloads efficiently
I think overall Spot is quite good. The UI is powerful, but it can feel a bit dense for some new users. More guided onboarding would help teams adopt advanced features faster, and deeper insights into Kubernetes resource usage would be beneficial. Overall, it is a really good platform that is quite mature and stable. I chose a rating of nine because it may sometimes be a bit overwhelming for newcomers, and there are also a few areas in which the EKS Kubernetes level granularity is a little missing. Overall, I think Spot is a really good and stable tool.
