CAST AI platform is compatible with the most popular cloud providers


Soon, all senior developers will have to deploy and manage their applications in the cloud. But today, this has become ridiculously complex, expensive, and monopolized by a small group of industry players.

Cloud optimization should be easier than that. Going multi-cloud should be effortless. Finding the best combination of price and performance should happen automatically.

We are building CAST AI to free developers from the countless manual tasks for cloud setup maintenance. We want to give them negotiating power when dealing with cloud service vendors.

But to achieve that, we need your help. Join our community, share your insight, and build the future of multi-cloud with us.
