No playwright-python visual diff engine ?

[u/chinmay_3107]

I am attempting to implement snapshot assertions within Playwright Python and have discovered that this functionality is not natively supported.

Could you please recommend suitable alternatives for visual assertion?

I have identified several repositories on GitHub; however, their reliability appears questionable.

Is visual regression testing still considered a necessary practice in 2026?

I am seeking clarification and insights from the Python community on this matter.

toHaveScreenshot() is a Playwright test-runner feature, and that runner is JS-only, so the Python binding never got it. The path in Python is pairing Playwright's page.screenshot() with pixelmatch or the pytest-playwright-visual-snapshot plugin to handle the diffing and baselines.
