Self hosting can be doable for constant small/medium size workloads You can handroll a lot with: https://github.com/nestybox/sysbox?tab=readme-ov-file https://gvisor.dev https://github.com/containers/bubblewrap?tab=readme-ov-file For hardware virtualized machines it much harder but you can do it via: https://github.com/firecracker-microvm/firecracker/ https://github.com/cloud-hypervisor/cloud-hypervisor Freestyle/other providers will likely provide better debugging experience but thats something you can probably get past for a lot of workloads. The time when you/anyone should think about Freestyle/anyone is when the load spikes/the need to create hundreds of VMs in short spikes shows up, or when you're looking for some of the more complex feature sets any given provider has built out (forks, GPUs, network boundaries, etc).

ecommend self hosting anything you do outside of your normal VPC. Sandboxes are the biggest possible attack surface and it is a feature of us that we're not in your cloud; If we mess up security your app is still fine.
In Launch HN: Freestyle – Sandboxes for Coding Agents
I'm working on an article deep diving into the differences between all of us. I think the goal of Freestyle is to be the most powerful and most EC2 like of the bunch. Daytona runs on Sysbox (https://github.com/nestybox/sysbox) which is VM-like but when you run low level things it has issues. Modal is the only provider with GPU support. I haven't played around with Blaxel personally yet. E2B/Vercel are both great hardware virtualized "sandboxes" Freestyle VMS are built based on the feedback our users gave us that things they expected to be able to do on existing sandboxes didn't work. A good example here is Freestyle is the only provider of the above (haven't tested blaxel) that gives users access to the boot disk, or the ability to reboot a VM.
