What do you like best?
They delivered. The product actually works and saves you money. What I appreciated in comparison to other tools on the market is that CAST AI is easy to start using. Sure, there are some quirks here and there, but generally the UI is easy to navigate. They also sent links to relevant sections in documentation and offered live help.
What do you dislike?
At first I was questioning the big promise on their website, but it turned out to be true. Other than that nothing negative really stood out, although my usage was rather light.
What problems are you solving with the product? What benefits have you realized?
As a young company, we don't have a cloud cost problem yet, but reading all the horror stories on the internet I decided to investigate what tools are out there. CAST AI turned out one of my favorites.
We will still have to grow a little bit before their paid offering saves us its monthly fee, but it's going to be a no-brainer once that happens. For now, I'll keep using the free observability functionalities and optimize some of the less dynamic parts in our infrastructure on my own.
