Puppeteer vs Vitest
The short version
- Each has a real cost: Puppeteer chrome and Firefox only, with no Safari or WebKit story; Vitest assumes Vite: projects on webpack or other bundlers lose the main advantage
- They diverge on capability: Puppeteer covers DevTools Protocol, Vitest covers Shares Vite config.

Only the attributes on which Puppeteer and Vitest actually diverge.
Identical on both: starting price (Free), pricing model (Open source, no licence fee), free tier (Yes), platforms (Linux, macOS, Windows), user rating (Not yet rated), category (Testing).

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Puppeteer
- Chrome and Firefox only, with no Safari or WebKit story
- Not a test framework: assertions, retries and reporting need Jest or similar bolted on
- Bundles a Chromium download, which makes installs large and awkward in constrained CI images
Vitest
- Assumes Vite: projects on webpack or other bundlers lose the main advantage
- Younger than Jest, so some plugins and matchers in the Jest ecosystem have no equivalent
- Jest compatibility is close but not exact, and unusual Jest configurations still need work to port

Answered from the vendors’ own pages
Puppeteer: Is Puppeteer free?
Yes, open source from the Chrome team.
Vitest: Is Vitest free?
Yes, open source under the MIT licence.
Puppeteer: Puppeteer or Playwright?
Playwright came from the same original team, adds WebKit and Firefox support, automatic waiting and a test runner. Puppeteer stays a focused Chrome automation library, which is simpler if automation rather than testing is the goal.
Vitest: Is Vitest compatible with Jest?
The API is deliberately Jest-compatible and most migrations are mechanical, though unusual configurations and some ecosystem plugins need attention.
Puppeteer: Can Puppeteer generate PDFs?
Yes, and it is one of the most common uses — rendering a page and printing it to PDF server-side.
Vitest: Do I need Vite to use Vitest?
It works without a Vite app but the main benefit — sharing one config and transform pipeline — only applies if you are already using Vite.
