Components Overview of OpenSandbox system components — server, execd, ingress, and egress.

Components

OpenSandbox is composed of several system components that work together to provide sandbox lifecycle management, in-sandbox execution, and network control.

Components

Component Description Details
Server FastAPI-based lifecycle control plane. Creates, monitors, and terminates sandboxes across Docker and Kubernetes. Python, REST API
Execd In-sandbox execution daemon. Provides HTTP APIs for shell commands, file operations, PTY sessions, and code interpreters. Go, Gin framework
Ingress HTTP/WebSocket reverse proxy for Kubernetes sandbox routing. Routes traffic to sandbox instances via header or URI mode. Go
Egress Per-sandbox FQDN-based egress control sidecar. Enforces allowlists, credential injection, and network policy. Go
