e2b builds open-source, secure sandboxed cloud environments for AI agents and AI applications. Its product is a set of isolated Linux microVMs in which agents can execute code, run terminal commands, process data and browse the web without touching production systems. The technical work spans AI agent infrastructure, microVM virtualization, code execution and cloud security.
The company's core offerings include E2B Sandboxes, an SDK for connecting AI agents to sandboxed environments, a managed cloud service, and self-hosted or bring-your-own-cloud deployment options for organisations with their own security requirements. The scale is notable: more than 1 billion sandboxes have been launched and the SDK records over 7 million downloads a month. Customers include Microsoft, Perplexity, Hugging Face, Manus and Groq, and e2b reports adoption by 94% of Fortune 100 companies.
Engineering themes at e2b include developer tooling and SDK design, web browsing automation, and the security model behind fast-starting isolated microVMs. The codebase is open source, and the company positions its infrastructure for frontier AI and agentic workflows. Its work sits at the intersection of AI/ML, developer tools, cloud infrastructure and enterprise software.
