Happo and Chromatic both run visual regression tests from Storybook stories; neither is a universal winner. Happo is worth a close look if you want accessibility regression checks in the same workflow and publicly listed snapshot pricing. Chromatic suits teams drawn to Storybook’s visual testing panel and its documented Storybook-and-CI workflow. Compare the browser coverage, compatibility, review process, and expected usage against your own repository before choosing.
What Happo and Chromatic do
Both services render Storybook stories, capture visual snapshots, and compare them with baselines to flag changes. Storybook describes visual tests as “the most efficient way to test your components”; that is Storybook’s characterization, not an independent comparison of these services.

Which workflow fits your team?
Consider Happo when
- You want accessibility regression checks alongside visual runs; Happo explicitly describes accessibility testing in this context.
- You also use Playwright or Cypress and want to evaluate a service whose integrations extend beyond Storybook.
- You need public snapshot tiers to make an initial budget estimate.
Consider Chromatic when
- Your team wants to work with Chromatic’s visual tests panel in Storybook and its documented CI workflow.
- You want to evaluate its documented browser coverage and configurable viewports against your product’s needs.
- Your team is comfortable verifying current pricing and allowances directly, since the cited product pages do not establish a comparable current price schedule.
Chromatic describes its workflow as running “both in Storybook and CI.” Happo also documents Storybook and CI integration. The practical distinction is how your team prefers to inspect, discuss, and approve changes—not simply whether CI is supported. Chromatic documentation · Happo Storybook screenshot testing

| Browser coverage | Starter lists Chrome and Firefox; Growth adds Safari; Pro and Enterprise list Chrome, Firefox, Safari, iOS Safari, and Microsoft Edge. | Product materials describe Chrome, Firefox, Safari, and Edge; a plan-by-plan inclusion comparison is not established by those materials. |
| Accessibility regression checks | Explicitly described alongside screenshot runs, and listed across plans on Happo’s pricing page. | Not established by the reviewed pages; do not assume an equivalent service. |
| Storybook requirement | The reviewed Storybook page does not state a minimum version; check current setup documentation. | The official addon listing states Storybook 7.6 or later; verify the current prerequisite before installing. |

Happo’s accessibility checks are not a substitute for evaluating your broader accessibility needs or a dedicated accessibility process. The reviewed Chromatic pages do not establish an equivalent offering, so ask Chromatic directly if that capability is material to your decision.

Rank #3
Chromatic’s reviewed product pages describe free access to get started, but do not establish a current price schedule or comparable quota. That is not enough evidence to call either service cheaper. Check Chromatic’s current terms and compare expected usage, overages, and included browsers directly.
Estimate usage before comparing bills
Snapshot demand depends on how many stories and variants you test, how many browsers or viewports you include, and how often checks run. Build a representative estimate from your repository rather than comparing headline plan prices alone.

- Count the stories and meaningful visual states you intend to test.
- List the browsers and viewports required for your users, then check which plan includes them.
- Estimate how often CI will run the suite, including pull requests and other workflows.
- Ask each vendor how snapshots or tests are counted, what happens at the allowance limit, and what overages or usage controls apply.
- Run a pilot on representative stories and review the diff and approval workflow before committing to a plan.
Review noise, baselines, and CI behavior in a pilot
Both products describe diff or review workflows, but the cited pages do not provide a controlled comparison of false positives, rendering accuracy, or review speed. Treat those as questions to test in your own application, not as established product rankings.
Recommended Free Tools
- Check whether reviewers can understand a change and approve or reject it in the workflow your team already uses.
- Observe how baseline updates work and who can approve them.
- Use representative stories with dynamic content, fonts, animations, and responsive layouts to see whether diffs are actionable.
- Confirm how checks report failures in your CI system and how developers rerun or investigate them.
- Verify required browsers, viewport sizes, security constraints, and Storybook compatibility with the exact versions in your repository.
ScreenshotNeo is a separate option for capturing pages
If your requirement is broader than Storybook component regression testing—such as capturing a public website as an image or PDF—ScreenshotNeo is a website screenshot API and MCP server, not a like-for-like replacement for Happo or Chromatic’s Storybook review workflows. It may be an alternative to try first for that capture use case: cookie and consent banners, newsletter popups, and chat widgets can be removed before a shot; bot checks, blank pages, and failed loads are not billed. Its MCP server offers screenshot tools for AI agents. ScreenshotNeo includes 1,000 screenshots monthly on its free plan with no card; paid plans start at $5 for 3,000.
For detailed API options and parameters, see the ScreenshotNeo documentation. Sign up for 1,000 free screenshots a month, with no card.
Frequently Asked Questions
Does Chromatic require a particular Storybook version?
Its official addon listing states Storybook 7.6 or later. Verify the current listing before installing.
Can either service’s visual tests replace accessibility testing?
Happo documents accessibility regression checks, but that alone does not establish that it replaces a broader accessibility evaluation. The reviewed Chromatic pages do not establish an equivalent service.
