Examples

Runnable examples demonstrating CubeSandbox features and integrations. Follow each project's README for prerequisites and setup instructions.

Getting Started and Images

Example Description
Code Sandbox Quickstart Create a sandbox, run Python and shell commands, work with files, and try core E2B-compatible APIs.
Browser Sandbox (Playwright) Run headless Chromium in a MicroVM and control it remotely through Playwright over CDP.
Custom nginx Image Build a minimal nginx image on top of cubesandbox-base and test the custom-template-image flow end to end.

Agents and Framework Integrations

Example Description
Claude Code Redirect Claude Code Bash tool calls into isolated CubeSandbox MicroVMs.
LangChain Use CubeSandbox as a command-execution tool with both LangChain 0.x and 1.x agents.
Pi Agent Connect Pi Agent tool execution to a CubeSandbox environment.
OpenClaw Configure the OpenClaw skill so agents can execute code in isolated MicroVMs.
OpenAI Agents SDK Connect E2BSandboxClient to CubeSandbox, including Shell Agent, pause/resume, and SWE-bench flows.
OpenAI Agents + Code Interpreter Run data-analysis agents using either generic E2B execution or a stateful Jupyter kernel.
SWE-bench with mini-swe-agent Automate SWE-bench coding tasks in isolated sandboxes with multi-model support and an RL training workflow.

Networking and Ingress

Example Description
Network Policy Try air-gapped, CIDR allowlist, CIDR denylist, and runtime policy-update scenarios.
Route-Aware Egress Verify sandbox egress through host routes when cube-router is enabled.
gRPC Ingress Connect a native gRPC client through CubeProxy's plaintext ingress on port 9090.
E2B Dev Sidecar Access a remote Cube cluster from an E2B SDK development environment without wildcard DNS.

Storage, Memory, and State

Example Description
Host Mount Mount host directories read-only or read-write into a sandbox at creation time.
Snapshot, Rollback, and Clone Run standalone SDK examples for snapshots, rollback, cloning, state preservation, and concurrency.
ivshmem Enable host/guest shared memory and try a ring-buffer protocol and mmap throughput benchmark.
Tencent Cloud COS Volume Plugin Deploy and exercise the binary or RPC COS volume plugin through its complete lifecycle.
S3-Compatible Volume Plugin Connect AWS S3, Tencent Cloud COS, Cloudflare R2, MinIO, or another S3-compatible backend.

Benchmarking

Example Description
cube-bench Measure sandbox creation and deletion latency at configurable concurrency, with a TUI, percentile reports, and JSON export.

::: tip Most SDK examples use the same environment variables (E2B_API_URL, E2B_API_KEY, and CUBE_TEMPLATE_ID). See Quick Start before running them. :::
