• Plugs into an existing suite with a few lines rather than requiring new tests.
• Server-side rendering removes machine-to-machine screenshot inconsistency.
• Good PR-based approval workflow that developers actually use.

• Clean, fast PR review experience.
• Genuinely affordable, with a workable free tier.
• Open source, so self-hosting is a real fallback.

• Screenshot-based billing escalates faster than teams expect.
• Dynamic content requires careful masking or you drown in false diffs.
• Responsive widths are rendered, not truly executed in each browser, which occasionally hides real issues.

• Fewer integrations than Percy or Applitools.
• Small team behind it.
• Limited cross-browser rendering options.

Teams with an existing E2E or Storybook suite who want visual coverage without new tests.
