What E2B does
E2B (legal entity: FoundryLabs, Inc., doing business as E2B) builds a cloud “sandbox runtime” for AI agents and AI-powered apps—giving each workload an isolated execution environment so agents can safely run generated code, perform data analysis, and (via computer-use) interact with a desktop-like environment. E2B positions itself as infrastructure for the “execution layer” of agent systems: instead of asking developers/enterprises to provision and maintain bespoke VM/container environments, E2B provides SDK-driven sandbox sessions that can be spun up quickly and run with enterprise security controls.
On the product side, E2B provides a managed cloud offering (E2B Cloud), plus deployment modes intended for enterprise control-plane requirements (e.g., “BYOC” / customer-controlled environments as described on the site). Developers integrate via SDKs (and related building blocks) to create sandbox sessions, execute code, and manage sandbox lifecycle; E2B also emphasizes open-source distribution of its runtime components (and a template system) so that agents and developer tooling can programmatically define how sandboxes are built.
Strategically, E2B appears to be scaling from early developer adoption toward enterprise and platform integrations. The company highlights very large usage metrics (e.g., “1B+ sandboxes started” and “10M+ monthly SDK downloads”) and states that a large share of Fortune 100 companies have signed up. It has also expanded its integration surface with ecosystem partners and standards—such as support in the OpenAI Agents SDK, a partnership to integrate MCP tools via Docker’s MCP catalog, and the ability to provision sandboxes through Stripe Projects—while continuing to ship platform improvements (e.g., Build System 2.0) and operational resilience updates (a published postmortem for a Jan 13, 2026 disruption).
