Happo is a strong choice when:

  • You want every plan, the free one included, to have unlimited users and unlimited concurrent runs.
  • You want accessibility testing included on every plan, alongside the screenshots.
  • You need Safari on iPhone and iPad, Vitest, or native iOS and Android apps through the Happo API.

Snapvisor tends to fit better when:

  • You want a larger free tier: 7,000 screenshots a month, against Happo's 5,000 snapshots in Chrome.
  • You want a lower paid entry point: Pro from $9/month with 15,000 included, against Happo Starter at $149/month.
  • You value an inspectable open-source engine and want to discuss self-hosting the Snapvisor fork with us.

FAQ

Yes. Happo runs a hosted MCP server with OAuth sign-in that lets an assistant list the comparisons for a commit, inspect diffs, and accept or reject them. Snapvisor's hosted MCP server is included on every plan, Free included, and lets agents create builds, upload screenshots, run diffs and approve changes without a CI pipeline.

You keep your Playwright, Cypress or Storybook setup. Replace the happo wrapper and happoScreenshot calls with Snapvisor's capture calls, and put Happo's component and variant into the screenshot name. Happo reports do not import as baselines, so your first Snapvisor build on your base branch becomes the new baseline. You can run both side by side while you switch. The Migrate from Happo guide has the full mapping.
