The short version
- Each has a real cost: Puppeteer chrome and Firefox only, with no Safari or WebKit story; WebdriverIO its lead maintainer's day job and the project's most visible sponsorship both sit with Sauce Labs, a closer single-vendor tie than some other OpenJS projects, worth weighing for teams that specifically want vendor-neutral tooling.
- They diverge on capability: Puppeteer covers DevTools Protocol, WebdriverIO covers WebDriver and BiDi protocol support.

What people use each for
The jobs each tool is most often brought in to do.
Puppeteer
- Generating PDFs or screenshots of rendered pages on a servernot WebdriverIO
- Scraping sites that require JavaScript executionnot WebdriverIO
- Automating browser tasks where a full test framework is unnecessarynot WebdriverIO
WebdriverIO
- A JavaScript or TypeScript team wanting a batteries-included test runner covering both web and mobile automationnot Puppeteer
- A team already using Sauce Labs or BrowserStack that wants first-class service plugin support for those platformsnot Puppeteer
- An organisation automating both browser and Appium-based mobile tests from one framework rather than two separate toolsnot Puppeteer
- A team wanting WebDriver BiDi protocol support for newer, more reliable browser automation than classic WebDriver alone providesnot Puppeteer
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
WebdriverIO
- Its lead maintainer's day job and the project's most visible sponsorship both sit with Sauce Labs, a closer single-vendor tie than some other OpenJS projects, worth weighing for teams that specifically want vendor-neutral tooling.
- Playwright has captured much of the newer end-to-end JavaScript testing mindshare, so WebdriverIO's plugin ecosystem and community size, while real, are smaller than Playwright's.
- The dual protocol support for both classic WebDriver and WebDriver BiDi adds real configuration complexity for teams that just want one straightforward automation path.
- Documentation and community answers assume a working knowledge of WebDriver concepts, so teams new to browser automation face a steeper ramp than a more opinionated, simpler framework.
- As with other OpenJS-governed projects, there is no vendor SLA or paid support tier for the framework itself, only for the commercial device clouds it integrates with.

Answered from the vendors’ own pages
Puppeteer: Is Puppeteer free?
Yes, open source from the Chrome team.
WebdriverIO: Is WebdriverIO owned by Sauce Labs?
No, it is governed by the OpenJS Foundation, though its lead maintainer works at Sauce Labs and Sauce Labs is a premium project sponsor.
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.
WebdriverIO: Is it free?
Yes, entirely open source with no licence fee.
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.
WebdriverIO: How does it compare to Playwright?
Both are capable, free JavaScript end-to-end testing frameworks; Playwright has a larger and faster-growing community currently, while WebdriverIO has a longer history and broader classic WebDriver protocol support.
