E2B is a cloud-based infrastructure platform designed to provide secure, isolated execution environments for code and shell commands. It functions as an ephemeral orchestrator that provisions lightweight virtual machines, allowing developers and autonomous agents to run untrusted processes within a sandbox that is completely separated from the host system.
The platform distinguishes itself through its focus on programmable, serverless workspaces that support the full lifecycle of cloud-based development. By utilizing hardware-level isolation and snapshot-based resumption, it enables the near-instant restoration of complex environments. Users can define reproducible configurations through versioned templates, ensuring that software dependencies and system settings remain consistent across every session.
The system provides a comprehensive suite of tools for managing remote resources, including real-time terminal stream multiplexing and filesystem synchronization. These capabilities allow for the automated execution of tasks, such as managing files, installing dependencies, and controlling the state of cloud instances to optimize resource usage. The platform is accessible via a command-line interface and automated APIs designed to integrate directly into development workflows.
