playwright-snapshots

Overview

Playwright ships first-party visual regression assertions through expect(page).toHaveScreenshot() (and the per-locator expect(locator).toHaveScreenshot()). Snapshots are stored in the repo under per-test, per-browser, per-OS PNG files; comparison happens locally and the test fails when the diff exceeds the configured threshold (playwright-snapshots).

This is the self-hosted option - no external service, no per-snapshot billing, but also no hosted UI for review (diffs are reviewed locally or via CI artifact uploads).
