Val Town is a serverless platform to run Typescript automations. You can think of it like Zapier for software developers. Because Val Town can’t launch a local browser, Kernel lets you use tools like Puppeteer or Playwright on Val Town by connecting to a remote browser session hosted on Kernel’s infrastructure.

​
Quick start with Puppeteer

  1. Create a free Kernel account and generate an API key from Settings → API Keys
  2. Remix this Kernel starter val
  3. Add it to your Val Town val’s Environment Variables (left sidebar) as KERNEL_API_KEY
  4. Click Run on puppeteer.ts
  5. View logs for output

​
Quick start with Playwright

Kernel also supports Playwright sessions. The steps are nearly identical:
  1. Remix this Kernel starter val
  2. Add your KERNEL_API_KEY to Environment Variables
  3. Set TMPDIR to /tmp to avoid Playwright file-system warnings
  4. Click Run on playwright.ts
  5. Check the logs for output
