Yes. Happo says free plans are available for open-source projects; maintainers should contact Happo to get started.
Yes. Happo says free plans are available for open-source projects. Its published instruction is to contact Happo to get started. The pricing page does not publish separate eligibility rules or confirm the exact monthly allowance for an approved open-source project.
How to request Happo’s open-source plan
- Visit Happo’s pricing page.
- Use the contact route there and explain that you maintain an open-source project.
- Ask Happo to confirm whether the project qualifies, what snapshot allowance applies, which browsers and features are included, and what happens if usage reaches the limit.
Happo’s FAQ says: “Absolutely! Free plans are available for open source projects. Talk to us and we’ll get things started.” The statement confirms availability, while leaving the qualification process and project-specific terms to Happo.
What Happo’s public free tier includes
Happo also describes a general free tier with 5,000 snapshots per month in Chrome, visual and accessibility testing, no credit card, and no time limit. It says this general tier can be used indefinitely for personal projects or to evaluate Happo before upgrading. The pricing page does not explicitly say that these are the exact terms or quota for an open-source project, so confirm the OSS offer directly.
What counts as a snapshot?
Happo defines a snapshot as one screenshot of one component variant in one browser. A rough monthly estimate is:
component variants × browsers × Happo runs per month = monthly snapshotsFor example, 20 component variants tested in Chrome on 10 runs use 200 snapshots, before accounting for any other browser coverage. Use the same calculation with your own component count, browser matrix, and run frequency when asking Happo about an allowance.
What happens at the free-plan limit?
Happo says a free account that reaches its quota is paused until the next usage cycle or an upgrade. If a project relies on visual checks in pull requests or releases, ask Happo whether an approved open-source account follows this same limit behavior and plan around a possible pause.
Happo’s published paid plans
The pricing page lists these monthly plans. Prices and quotas may change, so check the live page before budgeting.
| Plan | Monthly price | Snapshots | Additional snapshots |
|---|---|---|---|
| Starter | $149 | 50,000 | $0.006 each |
| Growth | $399 | 150,000 | $0.006 each |
| Pro | $749 | 300,000 | $0.006 each |
Browser coverage and features vary by paid tier. Compare the current plan details against the browsers and accessibility checks your project needs. These are vendor-listed prices, not independent usage or performance estimates.
Is Happo itself open source?
The fact that Happo provides a free plan for open-source projects does not mean its hosted service is open source. The Happo GitHub project is an open-source integration library; it is not evidence that the hosted testing platform itself is open source.
ScreenshotNeo: an alternative to try first
If your immediate need is to capture clean website screenshots for documentation, issue reports, or visual references, ScreenshotNeo is a website screenshot API and MCP server for developers. It is not a substitute for Happo’s visual and accessibility regression testing workflow. ScreenshotNeo’s free plan includes 1,000 shots per month with no card; paid plans start at $5 for 3,000 shots. Every feature is available on every plan.
One GET request returns a PNG, JPEG, WebP, or PDF. For example, request a WebP screenshot like this:
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpSee the ScreenshotNeo API documentation for request options. It accepts and removes cookie and consent banners, newsletter popups, and chat widgets before capture; each step can be turned off. Bot checks, blank pages, timeouts, failed loads, and cache hits cost nothing, and the response identifies the page verdict and billing status in headers. Its MCP server provides take_screenshot, get_page_info, and capture_pdf tools for AI agents and other MCP clients.
Sign up free for 1,000 screenshots a month with no card.
