<!-- Generated from cloud.mdx. DO NOT EDIT. -->

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.

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.

<Info>

When is a slot in use? A license slot is occupied when a test client is connected. As soon as your device is destroyed the slot becomes available immediately.

</Info>

Avoiding Slot Conflicts

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

<AccordionGroup>

<Accordion title="Set Maximum Concurrency in Vitest">

Limit concurrent tests to match your available license slots:

    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 and set maxConcurrency to that number or lower.

</Tip>

</Accordion>

<Accordion title="Use GitHub Concurrency Keys">

Prevent multiple workflow runs from competing for the same slots by using GitHub's concurrency controls:

    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
