E2B review

E2B ranks first because it is built around the exact job on this list: one isolated machine per agent session. Its site describes a Firecracker microVM per session with no shared kernel, an Apache-2.0 runtime and SOC 2 Type II, and lists HIPAA on the pricing page. Agents can run code, use a CLI and browser, or drive a full Linux desktop through E2B Desktop, which exposes screenshots, clicks and keyboard input for computer-use models. Templates let you bake tools such as Claude Code or Docker into a starting image. The Hobby tier is free with a one-time $100 credit, 20 concurrent sandboxes and 1-hour sessions. Pro costs $150 a month plus usage and raises sessions to 24 hours and concurrency to 100, expandable to 1,100 with add-ons. A default 2 vCPU sandbox bills $0.000028 per second for CPU. The fixed Pro fee is the main drawback for small teams, and BYOC sits on the Enterprise tier.
