What is E2B?

E2B (formerly known as e2b.dev) is a cloud platform for running AI-generated code in secure, isolated sandboxes. The platform provides infrastructure for executing untrusted code safely, enabling AI agents and applications to run code without security risks. E2B offers pre-configured environments for Python, JavaScript, and other languages, with instant startup times and scalable infrastructure. The platform is particularly valuable for AI coding assistants, data analysis applications, and any system requiring safe code execution. E2B provides both cloud-hosted and self-hosted deployment options, with pay-per-use pricing that scales with usage.
