Daytona Java SDK

The official Java SDK for Daytona, an open-source, secure and elastic infrastructure for running AI-generated code. Daytona provides full composable computers — sandboxes — that you can manage programmatically using the Daytona SDK.

The SDK provides an interface for sandbox management, file system operations, Git operations, language server protocol support, process and code execution, and computer use. For more information, see the documentation.

Installation

Add the dependency using Gradle:

dependencies {
    implementation("io.daytona:sdk:0.1.0")
}

or using Maven:

<dependency>
  <groupId>io.daytona</groupId>
  <artifactId>sdk</artifactId>
  <version>0.1.0</version>
</dependency>

Get API key

Generate an API key from the Daytona Dashboard ↗ to authenticate SDK requests and access Daytona services. For more information, see the API keys documentation.

Configuration

Configure the SDK using environment variables or by passing a configuration object:

• DAYTONA_API_KEY: Your Daytona API key
• DAYTONA_API_URL: The Daytona API URL
• DAYTONA_TARGET: Your target region environment (e.g. us, eu)

import io.daytona.sdk.Daytona;
import io.daytona.sdk.DaytonaConfig;

// Initialize with environment variables
Daytona daytona = new Daytona();

// Initialize with configuration object
DaytonaConfig config = new DaytonaConfig.Builder()
    .apiKey("YOUR_API_KEY")
    .apiUrl("YOUR_API_URL")
    .target("us")
    .build();
Daytona daytona = new Daytona(config);

Create a sandbox

Create a sandbox to run your code securely in an isolated environment.

import io.daytona.sdk.Daytona;
import io.daytona.sdk.Sandbox;
import io.daytona.sdk.model.CreateSandboxFromSnapshotParams;
import io.daytona.sdk.model.ExecuteResponse;

try (Daytona daytona = new Daytona()) {
    CreateSandboxFromSnapshotParams params = new CreateSandboxFromSnapshotParams();
    params.setLanguage("python");
    Sandbox sandbox = daytona.create(params);

    ExecuteResponse response = sandbox.process.codeRun("print('Hello World!')");
    System.out.println(response.getResult());

    sandbox.delete();
}

Examples and guides

Daytona provides examples and guides for common sandbox operations, best practices, and a wide range of topics, from basic usage to advanced topics, showcasing various types of integrations between Daytona and other tools.

Create a sandbox with custom resources

Create a sandbox with custom resources (CPU, memory, disk).

import io.daytona.sdk.Daytona;
import io.daytona.sdk.Image;
import io.daytona.sdk.model.CreateSandboxFromImageParams;
import io.daytona.sdk.model.Resources;

try (Daytona daytona = new Daytona()) {
    CreateSandboxFromImageParams params = new CreateSandboxFromImageParams();
    params.setImage(Image.debianSlim("3.12"));
    params.setResources(new Resources(2, null, 4, 8));
    Sandbox sandbox = daytona.create(params);
}

Create a sandbox from a snapshot

Create a sandbox from a snapshot.

import io.daytona.sdk.Daytona;
import io.daytona.sdk.model.CreateSandboxFromSnapshotParams;

try (Daytona daytona = new Daytona()) {
    CreateSandboxFromSnapshotParams params = new CreateSandboxFromSnapshotParams();
    params.setSnapshot("my-snapshot-name");
    params.setLanguage("python");
    Sandbox sandbox = daytona.create(params);
}

Execute commands

Execute commands in the sandbox.

// Execute a shell command
ExecuteResponse response = sandbox.process.executeCommand("echo 'Hello, World!'");
System.out.println(response.getResult());

// Run Python code
ExecuteResponse code = sandbox.process.codeRun("print('Sum:', 10 + 20)");
System.out.println(code.getResult());

File operations

Upload, download, and search files in the sandbox.

// Upload a file
sandbox.fs.uploadFile("Hello, World!".getBytes(), "path/to/file.txt");

// Download a file
byte[] content = sandbox.fs.downloadFile("path/to/file.txt");

// Search for files
List<Match> matches = sandbox.fs.searchFiles(rootDir, "search_pattern");

Git operations

Clone, list branches, and get status in the sandbox.

// Clone a repository
sandbox.git.clone("https://github.com/example/repo", "path/to/clone");

// List branches
Map<String, Object> branches = sandbox.git.branches("path/to/repo");

// Get status
GitStatus status = sandbox.git.status("path/to/repo");

Language server protocol

Create and start a language server to get code completions, document symbols, and more.

// Create and start a language server
LspServer lsp = sandbox.createLspServer("typescript", "path/to/project");
lsp.start("typescript", "path/to/project");

// Notify the LSP for a file
lsp.didOpen("typescript", "path/to/project", "path/to/file.ts");

// Get document symbols
List<LspSymbol> symbols = lsp.documentSymbols("typescript", "path/to/project", "path/to/file.ts");

// Get completions
CompletionList completions = lsp.completions("typescript", "path/to/project", "path/to/file.ts", 10, 15);
