Free and Pro
Understand monthly workflow usage, export branding, and the $9.99/year Pro subscription.
Before purchasing Pro
Check the pricing page for checkout availability. Pro is billed annually through Dodo Payments. There is no trial or early-adopter promotion.
What is included
Visual A/B, localization, responsive, accessibility, and UI testing are all included on Free in Chrome, within 20 completed workflows per month. Firefox 153+ has the same workflow allowance, full-quality exports, watermark rules, local library, and Pro licensing, but responsive device presets and browser locale simulation are disabled in both plans. Existing responsive/localized captures remain reviewable and exportable in Firefox. This new limited-feature target is not verified feature parity or a published Firefox listing; see browser compatibility and availability.
Free is not unlimited; Pro increases usage and adds watermark controls, not exclusive testing capabilities.

Free works without a SnapDiff website account or a license key. Pro does not move your capture library to a cloud service.
Visual A/B is not a traffic-split experiment, localization is not automatic translation, responsive presets are not physical-device or browser-engine validation, and axe checks do not certify WCAG compliance. Read each capability's scope.
How a workflow is counted
- One completed Single capture counts as one workflow.
- One completed A/B pair counts once, not twice.
- One completed Multi group of 2–5 images counts once.
- Failed attempts, annotations, retakes, downloads, and optional accessibility checks do not consume another workflow.
- Deleting saved captures does not reset monthly usage.
All capture, comparison, and annotation features supported by your browser, plus full-quality exports, are available within the Free allowance. When you reach the allowance, you can still work with saved captures and download them; wait for the monthly allowance to renew before starting more completed workflows.
Activate Pro
To activate your subscription:
- Open Get Pro in the extension.
- Complete the Dodo Payments hosted checkout.
- Copy the license key provided after purchase.
- Paste it into the extension's license dialog and activate that browser installation.
Keep your license key private. An active subscription supports up to three browser installations. To move an activation, deactivate it on a browser you no longer use before activating another. Activating Pro does not synchronize captures between browsers.
Renewal and cancellation
Pro is an automatically renewing yearly subscription, not a lifetime license or one-time purchase. The total subscription term is 10 years. Renewals stop at the end of that term unless it is extended.
Manage or cancel an active subscription through the Dodo Payments customer portal. Deactivating a license in the extension only removes it from that browser; it does not cancel subscription billing.
License status is rechecked weekly, and previously verified access can be cached during temporary outages or offline use. Status changes are not guaranteed to take effect immediately on an offline browser.
For export appearance, see watermarks and timestamps. For activation problems, see licensing troubleshooting.
