Plain language
A commercial service that rents disposable Linux sandboxes for AI agents to run code in.
As stated in the literature
A managed sandbox-as-a-service platform providing isolated execution environments for LLM agents.
Why it matters: Hosted sandboxes let teams ship code-executing agents without each one having to build and harden their own isolation infrastructure.
For example, an agent platform spins up a fresh E2B sandbox per user request, lets the agent install packages and run code inside, and tears it down when done.
