Modal
Editorial take
Modal is a computer you program with Python decorators. Factories use it when the sandbox is “run this image” and when someone needs a GPU. It is not Firecracker-as-a-product and not a coding agent. Idle billing is a vendor claim — read the current pricing page.
E2B
Editorial take
E2B is the default noun for “agent sandbox” in 2026. MicroVMs are the isolation story; session length is the product story. We will not quote cold-start milliseconds we did not measure. BYOC/self-host exists in docs — confirm current support before you promise air-gap.
