title: Process and Code Execution
description: Execute code in your sandboxes using stateless and stateful execution.
---


Process and code execution are available through the `process` module of a sandbox. Code and commands run inside the sandbox, so untrusted or generated code executes in isolation from your application.

The `process` module covers running code snippets in Python, JavaScript, and TypeScript, with stateless execution or a persistent interpreter context, executing shell commands, and sessions: independent shells whose state persists across commands and that run long-lived processes in the background. For interactive terminal sessions, see [Pseudo Terminal (PTY)](/docs/en/pty). For real-time log streaming from long-running session commands, see [Log Streaming](/docs/en/log-streaming).

## Code execution

Daytona provides methods to execute code in sandboxes. You can run code snippets in multiple languages with support for both stateless execution and stateful interpretation with persistent contexts.

- [Run code (stateless)](#run-code-stateless): run independent code snippets where each execution starts from a clean interpreter state; inherits the sandbox language that you choose at [sandbox creation](/docs/en/sandboxes#create-sandboxes). Supports Python, JavaScript, and TypeScript.
- [Run code (stateful)](#run-code-stateful): run Python code in a persistent interpreter context with variables, imports, and state to carry across executions; available in every SDK.

### Run code (stateless)

Run code snippets in sandboxes using stateless execution. Each invocation starts from a clean interpreter, making it ideal for independent code snippets.

#### Artifacts

Stateless `code_run` responses can include an `artifacts` field. When your code produces matplotlib charts, the SDK strips chart metadata from `result` and returns it in the `artifacts.charts` field.

plt.show()
'''

### Run code (stateful)

Run Python code with persistent state using the code interpreter. You can maintain variables and imports between calls, create isolated contexts with optional working directories, list active contexts, and stream stdout, stderr, and errors via callbacks.

## Command execution

Daytona provides methods to execute shell commands in sandboxes. You can run commands with working directory, timeout, and environment variable options. The default timeout is 10 seconds when not specified.

Git operations assume you are operating in the sandbox user's home directory (e.g. **`workspace`** implies **`/home/[username]/workspace`**). Use a leading **`/`** when providing absolute paths.

### Execute commands

Execute shell commands in sandboxes by providing the command string and optional parameters for working directory, timeout, and environment variables. 

You can also use the `daytona exec` CLI command for quick command execution.

### Entrypoint session
