I've hopelessly lost track of the "vm for agents, typically with a handy CLI for people also" space. Fly.io sprites. Modal. Blaxel. Morph. Daytona. Runloop. Ascii Box... I'm surely only scratching the surface. Then there's also the incumbent mega clouds for vms like Digital Ocean, and AWS/GCP/Azure compute instances etc. Also Blaxel is a YC company too?

I need an explainer. Each of these products is carving out a particular niche, or competing directly for someone else's niche with better X or Y, and I'd love to see some analysis of the landscape.
