testdriverai 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.

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
