Create a sandbox. Run your code.

Add sandboxes to your app with the SDK and CLI.

SDK reference CLI
create.ts
import { Sandbox } from '@tangle-network/sandbox';

const tangle = new Sandbox({
  apiKey: process.env.TANGLE_API_KEY!,
  baseUrl: 'https://sandbox.tangle.tools',
});
const box = await tangle.create({
  environment: 'universal', maxLifetimeSeconds: 900,
});
await box.waitFor('running');
npm install @tangle-network/sandbox

Give every agent an isolated workspace.

Run coding agents interactively or in the background.
