# E2B Code Interpreter Sandboxes > Secure isolated cloud VMs for executing AI-generated code. Open-source. ## Installation ```bash pip install e2b-code-interpreter npm i @e2b/code-interpreter export E2B_API_KEY=your_key_here # get at https://e2b.dev/dashboard ``` ## Python Usage ```python from e2b_code_interpreter import Sandbox # Basic execution with Sandbox() as sandbox: result = sandbox.run_code("x = 1 + 1; print(x)") print(result.logs.stdout) # ["2"] # Stateful multi-step session with Sandbox() as sandbox: sandbox.run_code("data = [1, 2, 3]") r = sandbox.run_code("print(sum(data))") print(r.logs.stdout) # ["6"] ``` ## TypeScript Usage ```typescript import { Sandbox } from "@e2b/code-interpreter" const sandbox = await Sandbox.create() const result = await sandbox.runCode("print(1 + 1)") console.log(result.logs.stdout) await sandbox.kill() ``` ## Use With Claude AI Agent ```python from anthropic import Anthropic from e2b_code_interpreter import Sandbox client = Anthropic() sandbox = Sandbox() response = client.messages.create( model="claude-sonnet-4-6", max_tokens=1024, messages=[{"role": "user", "content": "Write Python to compute fibonacci(10)"}] ) code = response.content[0].text result = sandbox.run_code(code) print(result.logs.stdout) sandbox.kill() ``` ## Key Features | Feature | Detail | |---------|--------| | Isolation | Each sandbox = fresh cloud VM | | Stateful | Variables persist within session | | Languages | Python, JavaScript/TypeScript | | Outputs | stdout, stderr, rich results (plots, tables) | | Self-hostable | GCP (prod-ready), AWS (in progress), Azure (planned) | ## Self-Hosting ```bash # GCP (production-ready) terraform apply -var-file=gcp.tfvars ``` ---
