SDK Overview

OpenSandbox provides SDKs for multiple programming languages, enabling you to create, manage, and interact with secure sandbox environments from your preferred language.

Available SDKs

Sandbox SDKs

Low-level SDKs for direct sandbox interaction:

Python

Full async/sync support with comprehensive file and command APIs

JavaScript/TypeScript

Modern TypeScript SDK with Node.js and browser support

Kotlin/Java

Type-safe JVM SDK with builder pattern and try-with-resources

C#/.NET

IAsyncDisposable SDK supporting .NET Standard 2.0+

Code Interpreter SDK

Code Interpreter

High-level SDK for executing Python, Java, Go, TypeScript code with state persistence

Choosing the Right SDK

Use Sandbox SDKs when you need:

Direct control over sandbox lifecycle (create, pause, resume, kill)
File system operations (read, write, search, delete)
Command execution with streaming output
Network endpoint management
Custom health checks and resource monitoring
Administrative tasks (listing/managing multiple sandboxes)

Use Code Interpreter SDK when you need:

Code execution in multiple languages (Python, Java, Go, TypeScript)
State persistence across executions (variables/imports retained)
Multi-language contexts in a single sandbox
Simplified API for running code snippets
Pre-configured runtime environments

Common Capabilities

All Sandbox SDKs share these core capabilities:

Lifecycle Management

Python
JavaScript
Kotlin
C#

# Create with timeout
sandbox = await Sandbox.create(
    "ubuntu",
    connection_config=config,
    timeout=timedelta(minutes=30)
)

# Renew expiration
await sandbox.renew(timedelta(minutes=30))

# Pause/Resume
await sandbox.pause()
resumed = await Sandbox.resume(
    sandbox_id=sandbox.id,
    connection_config=config
)

// Create with timeout
const sandbox = await Sandbox.create({
  connectionConfig: config,
  image: "ubuntu",
  timeoutSeconds: 30 * 60
});

// Renew expiration
await sandbox.renew(30 * 60);

// Pause/Resume
await sandbox.pause();
const resumed = await sandbox.resume();

// Create with timeout
Sandbox sandbox = Sandbox.builder()
    .connectionConfig(config)
    .image("ubuntu")
    .timeout(Duration.ofMinutes(30))
    .build();

// Renew expiration
sandbox.renew(Duration.ofMinutes(30));

// Pause/Resume
sandbox.pause();
sandbox.resume();

// Create with timeout
var sandbox = await Sandbox.CreateAsync(new SandboxCreateOptions
{
    ConnectionConfig = config,
    Image = "ubuntu",
    TimeoutSeconds = 30 * 60
});

// Renew expiration
await sandbox.RenewAsync(30 * 60);

// Pause/Resume
await sandbox.PauseAsync();
var resumed = await sandbox.ResumeAsync();

Command Execution

Python
JavaScript
Kotlin
C#

execution = await sandbox.commands.run("echo 'Hello!'")
print(execution.logs.stdout[0].text)

const execution = await sandbox.commands.run("echo 'Hello!'");
console.log(execution.logs.stdout[0]?.text);

Execution execution = sandbox.commands().run("echo 'Hello!'");
System.out.println(execution.getLogs().getStdout().get(0).getText());

var execution = await sandbox.Commands.RunAsync("echo 'Hello!'");
Console.WriteLine(execution.Logs.Stdout.FirstOrDefault()?.Text);

File Operations

Python
JavaScript
Kotlin
C#

# Write
await sandbox.files.write_files([
    WriteEntry(path="/tmp/file.txt", data="content", mode=644)
])

# Read
content = await sandbox.files.read_file("/tmp/file.txt")

# Search
files = await sandbox.files.search(
    SearchEntry(path="/tmp", pattern="*.txt")
)

// Write
await sandbox.files.writeFiles([
  { path: "/tmp/file.txt", data: "content", mode: 644 }
]);

// Read
const content = await sandbox.files.readFile("/tmp/file.txt");

// Search
const files = await sandbox.files.search({
  path: "/tmp",
  pattern: "*.txt"
});

// Write
sandbox.files().write(List.of(
    WriteEntry.builder()
        .path("/tmp/file.txt")
        .data("content")
        .mode(644)
        .build()
));

// Read
String content = sandbox.files().readFile("/tmp/file.txt", "UTF-8", null);

// Search
List<EntryInfo> files = sandbox.files().search(
    SearchEntry.builder()
        .path("/tmp")
        .pattern("*.txt")
        .build()
);

// Write
await sandbox.Files.WriteFilesAsync(new[] {
    new WriteEntry { Path = "/tmp/file.txt", Data = "content", Mode = 644 }
});

// Read
var content = await sandbox.Files.ReadFileAsync("/tmp/file.txt");

// Search
var files = await sandbox.Files.SearchAsync(
    new SearchEntry { Path = "/tmp", Pattern = "*.txt" }
);
