Percy vs Argos

Free tier available

From $100 per month (Pro, usage-based, 35k screenshots included)

BrowserStack no longer publishes standalone Percy prices — its own /percy/pricing page is gone and Percy now appears bundled into wider BrowserStack packages (it is one of the products in Team Ultimate at $375/month billed annually) or priced by sales. Paid plans still include a fixed screenshot allowance with overage on top, so multiply pages x widths x browsers x commits before committing — this is where budgets are misjudged.

Pro is usage-based from $100/month including 35,000 screenshots, with extras at $0.004 each ($0.0015 for Storybook). SSO is a paid add-on: $50/month for GitHub, $200/month for SAML.

5,000 screenshots a month, unlimited users and projects.

Hobby plan is free forever with up to 5,000 screenshots; free for open-source projects.

• 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.

Small and mid-sized teams wanting visual review in PRs at a sane price.
