The short version

  • Each has a real cost: Percy pixel-based diffing generates more false positives from font rendering and anti-aliasing noise than Applitools' AI-based comparison, which trains some teams to start ignoring diff alerts over time.; Puppeteer chrome and Firefox only, with no Safari or WebKit story
  • They diverge on capability: Percy covers Screenshot diffing, Puppeteer covers DevTools Protocol.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Percy

  • Pixel-based diffing generates more false positives from font rendering and anti-aliasing noise than Applitools' AI-based comparison, which trains some teams to start ignoring diff alerts over time.
  • It is billed separately from core BrowserStack device testing, and stacking Percy with other BrowserStack modules such as Accessibility Testing materially increases total contract value beyond the headline device testing price.
  • Paid tier pricing above the free tier is not transparently published as a fixed number, requiring a quote to know actual cost at scale.
  • The free tier's 5,000-screenshot cap is easy to exceed for any team running visual tests across multiple browsers and viewports on every commit, pushing many active projects into a paid tier faster than the free number suggests.
  • As part of a larger acquired portfolio, Percy's roadmap priority within BrowserStack's broader product strategy is less certain than it would be as a standalone company's sole focus.

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

Answered from the vendors’ own pages

Percy: Is Percy free?

Yes for up to 5,000 screenshots a month with unlimited users and projects; beyond that it is a paid, quote-priced module.

Puppeteer: Is Puppeteer free?

Yes, open source from the Chrome team.

Percy: Is Percy included if I already pay for BrowserStack device testing?

No, it is billed separately by screenshot volume, not bundled into core device testing plans.

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.

Percy: How does it compare to Applitools?

Percy uses pixel-based diffing, which is generally cheaper per screenshot but produces more false positives than Applitools' AI-based perceptual comparison.

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.
