| Fact | E2B | microsandbox |
|---|---|---|
| Company | E2B says it began as a project in March 2023, founded by Tomas Valenta and Vasek Mlejnsky. | Microsandbox is designed and engineered by Super Rad Company, whose stated purpose is building tools for the agentic future. |
| Isolation | Each sandbox runs in its own Firecracker microVM and kernel, without sharing a filesystem or memory with another customer's sandboxes. | Each sandbox is a microVM with its own Linux kernel, filesystem, and network boundary, rather than a container sharing the host kernel. |
| License | The runtime and published infrastructure are licensed Apache-2.0. | The runtime is open source under the Apache 2.0 license. |

Pick E2B if…
E2B suits teams building AI agents that need isolated execution, code interpretation, or desktop interaction. Self-hosting and BYOC are options for teams with those deployment needs.
Pick microsandbox if…
microsandbox may suit developers and teams that need to run untrusted workloads locally or on their own infrastructure. Its language SDKs, CLI, and MCP workflows support several ways to connect to the runtime.
