What it solves
The problem
Our editors cannot tell which page variant performs better.
What your site gets
The site has controlled tests with results measured against defined goals.
Questions buyers ask
- Who enters an experiment?
- Operators configure eligible audiences and consenting visitors receive an allocation.
- How are variants selected?
- Experiments use weighted allocation for page and campaign variants.
- When is a winner reported?
- Winner reports are gated by the configured evidence threshold.
Use it in your project
Set the audience, allocation and goal before running a test. Review the results against the configured evidence threshold before declaring a winner.
Picture it on your site
For a page test, write down the question, audience and goal before choosing the allocation. Review whether the evidence threshold is appropriate and avoid treating an early difference as a settled answer. The package supports a recorded comparison; the team still needs to interpret the result and decide whether the change serves visitors.

Run and measure your next campaign
- Allocate visitors to page or campaign variants.
- Report goal performance with statistical decision thresholds.
Is this right for your project?
Start with a useful campaign question
Choose the audience, action or measurement you actually need before adding another marketing workflow. A package is useful when it connects that task to the content and records your team already manages. Define what a successful result means and who checks it, rather than treating an enabled integration or a growing list of records as proof that the campaign is working.
Keep collection and interpretation separate
Verify the supported data flow with a small, recognisable example, then inspect where the result appears and how fresh it is. External services, consent choices and reporting windows can affect what you see. Your team remains responsible for those settings and for interpreting the result; the extension should make the workflow inspectable, not promise an improvement in sales or traffic.
One customer organisation; up to 5 named users. Each entitlement covers one production website or application and up to two non-production environments, with a maximum of three active installations.
12 months of protected downloads, updates and included standard support.
You may ask Capell for a full refund within 14 days of purchase. Requests are assessed case by case against the recorded order, access and support history. This applies to live paid first-party packages; third-party author sales have separate terms. Read the Refund Policy
Renewal is charged at the price current when you renew. The price is shown before you pay.
Marketplace listings can describe install impact and data access.
This installs as a Composer package. Check its removal guidance and retained-data policy before uninstalling it.
Paid checkout adds access to the purchasing account after payment. Review compatibility and site impact, then follow the installation steps for this package.
This listing has no page of its own in the demo. Open the demo to see Capell running.
Before you install
Review the impact below before running the commands in a covered Capell application, starting with a non-production environment. Required dependencies are listed above.
- Admin and public surfaces
- The package declares: administration screens, frontend integration, public routes. Review the release documentation for configuration and exposure in your application.
- Data and migrations
- Database migrations are declared. The installation flow can change your database; back up data and review the release migrations before installing. Uses package-local configuration and Capell metadata needed to enable the feature.
- Background work
- Scheduled background work is declared. Keep the host scheduler running and check the release documentation for queue workers, frequencies and pruning configuration.
- Access controls
- Package access controls are declared. Review role grants and the host authorisation configuration before allowing users into the new workflow.
- Removal and retained data
- A verified uninstall and retained-data assessment is not available here. Removing the Composer package does not establish that its data is deleted. Confirm cleanup, retention and dependencies with the publisher before removal.

Before checkout
Know who owns access and what happens next
Payment, customer account ownership, site activation, and package access are separate steps. The checkout reference lets support trace a problem without moving the licence to another account.
Who processes the payment and taxes?
Lemon Squeezy is the seller and hosts paid marketplace checkout. Any VAT due is calculated and added by Lemon Squeezy at checkout, and Lemon Squeezy issues the tax receipt. Capell does not collect card details; it activates the matching marketplace licence after payment is confirmed.
Which account owns the licence?
The signed-in customer account that completes checkout owns the Capell licence, support history, and future install access. Capell surfaces a link to the tax receipt issued by Lemon Squeezy. Use the intended organisation account before paying.
How does the site receive package access?
The install flow connects the licence to the requesting site. Paid and private packages then use authenticated Composer access from the customer account that owns the licence.
What happens if checkout is cancelled or expires?
No licence is created until Lemon Squeezy confirms payment. After a cancellation or expired quote, return to the same marketplace listing and start a fresh checkout so price and package details are recalculated.
How do I request a refund?
There is no self-service refund button. Email [email protected] within 14 days of purchase with the account email, the order or receipt reference, the package and your reason. Capell reviews the recorded purchase and, where approved, submits the refund through Lemon Squeezy. Read the Refund Policy
What should I do if access does not appear?
Keep the checkout reference from the page or receipt and contact support before trying another account. Support can trace the payment, customer account, licence, and connected site from that reference.
