Runtime authorization & controls
Apache-2.0 sandbox infrastructure that gives agents isolated cloud environments to execute model-generated code, process files and run tools, controlled from Python or JavaScript SDKs. Sandboxes bound where agent code runs, but E2B is an execution boundary rather than a policy decision point for tool authorization.

Useful conversation with: AI platform engineer, Head of engineering, Application security engineer.
Show me an agent running untrusted generated code in an E2B sandbox with filesystem and network limits, then show the same workload on a self-hosted E2B cluster.
Support labels reflect the supplied research. Documentation and vendor claims are not independent product tests. “Not established” means the researcher did not find support; it does not prove a capability is absent.
Documented by provider
E2B provides isolated sandboxes in which agents execute code, process data and run tools, started and managed through Python and JavaScript SDKs.
Limit: Documentation fetched does not detail the isolation technology or a formal security boundary assessment.
Documented by provider
E2B infrastructure can be self-hosted using Terraform on AWS, Google Cloud, Azure or a general Linux machine, and the repository is Apache-2.0 licensed.
Limit: Self-hosted feature parity with the cloud service is not stated.
Listing does not imply partnership, supplier status, a working DutyGraph integration, or a compliance certification.
