Best alternatives to E2B in 2026
When an AI assistant writes code and then needs to actually run it — to check it works, plot a chart, or process a file — that code has to execute somewhere. Running untrusted, AI-generated code directly on your own computer or servers is risky: a bug or a bad instruction could delete files or make unwanted network calls. E2B is a disposable, locked-down computer in the cloud that spins up in a fraction of a second, runs that code safely away from anything important, and then disappears. E2B provides secure, ephemeral cloud sandboxes built on Firecracker microVMs — the same lightweight virtualization technology AWS Lambda uses — with sandbox startup times under 200 milliseconds. It ships Python and TypeScript SDKs, supports session durations up to 24 hours on paid tiers, and gives sandboxes real internet access and a terminal, which is what lets an AI agent actually browse, install packages, and interact with tools instead of running in total isolation. The core SDK is open source, and E2B also offers bring-your-own-cloud, on-premises and self-hosted deployment options for teams with stricter compliance needs. Pricing starts free with $100 in usage credits, moves to a Pro plan at $150/month plus usage, and scales to custom Enterprise pricing.
