Pay for what you test. Bring the whole team.

One screenshot of one component variant, story, or page, in one target. An accessibility check of it counts as one too. To see how many you’d take in a month, use the estimator.

Every account starts on the free plan: 5,000 snapshots a month in Chrome, with accessibility testing and unlimited users, and no credit card. Try Happo on a real project with it, and upgrade when you want more browsers or more snapshots.

We let you know when you get close. On a paid plan, snapshots over what it includes cost the price listed with the plan, and you can set a budget limit so a busy month never surprises you. On the free plan, Happo pauses until the next month starts or you upgrade, and never bills you.

An animated snapshot counts as three snapshots, however many frames it holds. A story that comes out as a still image counts as one.

Yes. Partial runs render only the stories or components a pull request touched and carry the rest over from your base branch; only what Happo renders counts. Fewer targets help too: start with the browsers your users have most, and add more later.

No. Every plan, the free one included, has unlimited users and unlimited concurrent runs. Invite everyone who touches the UI.

Yes, on the Pro and Enterprise plans. An annual plan’s snapshots are pooled over the 12 months, which smooths out busy months and makes the cost easy to predict.

By credit card, ACH, or wire transfer, through Stripe.

Yes. Changes are prorated within the billing cycle. Cancel a monthly plan from your account settings and you keep access to the end of the cycle, with no cancellation fee.

Chrome, Firefox, Safari, Edge, and Safari on iPhone and iPad. Each plan lists the browsers it includes; Pro and Enterprise include them all.

Storybook, Playwright, and Cypress, plus native iOS and Android apps through the Happo API and a custom integration for anything else. It runs in GitHub Actions, CircleCI, Azure DevOps, and the rest.

Yes. SAML 2.0 single sign-on with most identity providers is part of the Enterprise plan, and it can assign roles from SAML attributes. See the SSO docs.

Yes. Tell us about your project and we’ll set you up.

Of course. Ask for one here, and one of us will show you Happo and how it fits into your CI.

No seats: every plan has unlimited users. Accessibility testing is included on every plan, where many tools sell it separately, and animation testing comes with it. Happo renders in every major browser, Safari on iPhone included. And when you email support, the people who build Happo reply.

Henric Persson and Joe Lencioni, who built the first version in 2014 and have run it ever since. Happo is self-bootstrapped, with no investors, so the only people we answer to are the teams who use it. More about us.
