testdriver:cloud

Cloud pricing is based on device-seconds: the amount of time your tests run on our infrastructure.

• Zero Setup — Start testing immediately. No DevOps required.
• Free Tier — Get started with a limited preview at no cost.
• Pay As You Go — Only pay for the device-seconds you use.

Get Started

Cloud is the default when you follow the Quickstart guide. <Card title="Try the Quickstart" icon="play" href="/v7/quickstart"

Set your API key and start testing in minutes.

Parallel Testing Limits

Your account has a set number of license slots that determine how many devices can run simultaneously. You can view your available slots in the TestDriver Dashboard.

Avoiding Slot Conflicts

To prevent tests from failing due to exceeding your license slot limit, we recommend two key configurations:

```javascript vitest.config.mjs
import { defineConfig } from 'vitest/config';
import { TestDriver } from 'testdriverai/vitest';

export default defineConfig({
  test: {
    testTimeout: 900000,
    hookTimeout: 900000,
    maxConcurrency: 5, // Set to your license slot limit
    reporters: ['default', TestDriver()],
    setupFiles: ['testdriverai/vitest/setup'],
  },
});
```

<Tip>
  Check your slot count at [console.testdriver.ai](https://console.testdriver.ai) and set `maxConcurrency` to that number or lower.
</Tip>

```yaml .github/workflows/test.yml
name: Tests

on:
  push:
    branches: [main]
  pull_request:

# Prevent concurrent runs from competing for license slots
concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
  cancel-in-progress: true

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - name: Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: '20'

      - name: Install dependencies
        run: npm install

      - name: Run tests
        run: vitest run
        env:
          TD_API_KEY: ${{ secrets.TD_API_KEY }}
```

The `concurrency` block ensures:
- Only one workflow run per branch runs at a time
- New pushes cancel in-progress runs on the same branch
- Different branches/PRs can run in parallel (up to your slot limit)

When to Consider Self-Hosted

Cloud is perfect for getting started and for teams that want zero infrastructure management. However, you might consider Self-Hosted if you:

• Want to escape per-second billing with a flat license fee
• Require greater concurrency than offered in Cloud plans
• Need full control over your infrastructure and privacy
• Want to use your own AI API keys
• Require custom hardware configurations
• Have high test volumes that make self-hosting more economical
