Detect Playwright in any GitHub repo

Playwright is Microsoft's end-to-end testing framework for Chromium, Firefox and WebKit, with auto-waiting and trace viewer.

Why show Playwright on your README

E2E coverage is a quality signal; playwright.config is detected so the card shows the project is tested in real browsers.

How Playwright is detected

Stack Fingerprint reads the repo's full file tree in one GitHub API call and flags Playwright when it finds any of these:

  • Files or folders: /^playwright\.config/
  • Dependencies in package.json: @playwright/test, playwright

Playwright README badge

A static badge you can paste anywhere in Markdown:

![Playwright](https://img.shields.io/badge/Playwright-2EAD33?style=for-the-badge&logo=playwright&logoColor=white)

Or let the repo describe itself

Static badges go stale the moment you swap a dependency. A Stack Fingerprint card is generated from the repo, so Playwright (and everything around it) appears or disappears on its own:

Replace OWNER/REPO with your repository, or open the builder to pick a theme and layout.
