Why people look elsewhere
Where E2B fits badly, from its provider page.
- A long-running agent: the default timeout kills the sandbox after five minutes and commands do not reset it.
- Memory above 8 GiB, or any GPU workload.
- A client-facing link that must be private: public URLs have no authentication by default.
The alternatives, cheapest always-on agent first
Monthly machine cost at list prices, before any AI model. ✱ means it cannot run that workload exactly as described; the provider page says why.
