Yes. Happo says free plans are available for open-source projects, and its published next step is to contact the company to get started. The public pricing page does not specify OSS eligibility rules or the exact allowance an approved project receives.
How to request Happo’s open-source plan
Happo’s pricing page says: “Absolutely! Free plans are available for open source projects. Talk to us and we’ll get things started.” Use the contact route provided on Happo’s pricing page to ask about an open-source project.
The page does not publish qualification criteria, a review timeline, or a distinct snapshot quota for OSS projects. Ask Happo to confirm whether your project qualifies and what plan limits and browser coverage would apply before relying on a particular allowance.
What Happo’s general free plan includes
Happo’s pricing page, accessed October 3, 2026, describes a general free plan with 5,000 snapshots per month in Chrome, visual and accessibility testing, no credit card, and no time limit. Happo says this tier can be used indefinitely for personal projects or to evaluate the service. That description is separate from its OSS FAQ, so it should not be treated as confirmation that an approved open-source project receives exactly those same terms. Source: Happo pricing.
How a snapshot is counted
Happo defines a snapshot as one screenshot of one component variant in one browser. Its estimate for monthly usage is component variants × browsers × Happo runs per month. For example, if a project captures 12 variants in one browser on 20 runs during a month, that is 240 snapshots under this estimate.
What happens at the free quota
Happo says a free account pauses after reaching its quota until the next usage cycle or an upgrade. If uninterrupted runs matter, ask how the quota would work for the OSS offer and plan expected variant, browser, and run volume accordingly. Source: Happo pricing.

Paid tiers if the free allowance is not enough
Happo lists the following monthly prices and snapshot quotas on its pricing page, accessed October 3, 2026. These are vendor-published figures and may change; check the live page before choosing a plan. Browser coverage and features vary by paid tier.
| Plan | Monthly price | Snapshots per month | Additional snapshots |
|---|---|---|---|
| Starter | $149 | 50,000 | $0.006 each |
| Growth | $399 | 150,000 | $0.006 each |
| Pro | $749 | 300,000 | $0.006 each |
These listed paid-plan prices do not establish the terms of Happo’s separate OSS offer. Confirm your project’s actual terms with Happo.
Is Happo itself open source?
A free plan for open-source projects does not mean the hosted Happo service is open source. Happo’s GitHub project, happo/happo, is an open-source integration library; it is not evidence that the hosted testing service itself is open source.

If you need website screenshots rather than Happo’s component-based visual and accessibility regression testing, ScreenshotNeo is a separate screenshot API and MCP server for developers. One GET request can return a PNG, JPEG, WebP, or PDF. Its focus is clean website captures: it accepts cookie or consent banners and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture, with each step configurable.
ScreenshotNeo is not a substitute for Happo’s visual regression and accessibility-testing workflow. It is an option when the task is capturing website pages or PDFs through an API or AI-agent MCP tools.
One-call example
For a website screenshot, send a GET request with your API key and the target URL. See the ScreenshotNeo API documentation for request options.
