System requirements
All the stacks sold through this website require RapidWeaver and the Stacks plugin. They will not install or work with any other publishing platforms (like Flow, Drupal, Blocs or Wordpress).

We recommend you aim towards installing the latest version of RapidWeaver that your computer is capable of running (preferably RapidWeaver 7 or greater) and Stacks 3 or later. Both are a separate purchase if you do not own them already.

Stacks4Stacks generously provides you fully-functioning free demo versions of everything sold on this website. This enables you to fully test addons before committing to a purchase. There are no time or functionality limitations applied.

If you cannot get the free demo version to work, DO NOT proceed with purchasing the stack - because the purchased stack is unlikely to work any better for you. Please request technical assistance first.

License agreement

You may use a purchased stack an unlimited number of times in personal or commercial projects and request technical support.

We permit you to install stacks onto all computers that you own. You are permitted to make private archival backup copies (e.g. iCloud, Disk Blaze, Google Drive or Dropbox).

You may not resell, redistribute or make a stack available for download, remove copyright credits, license information, or claim the stack to be your own creation. This includes free stacks, demo stacks or paid stacks, in modified or unmodified states.

The software is provided "as is" without any implied or expressed warranty of merchantability or fitness for purpose. In no event shall the authors or copyright holders be liable for any claim, damages or other liability, whether in an action of contract, tort or otherwise arising from, out of or in connection with the software or the use or other dealings in the software.

Refund policy
By purchasing from this website, you agree that your purchase will be available immediately via digital download and that you waive your statutory right of withdrawal.

All purchases are final. Refunds cannot be provided (we physically cannot un-download or remove stacks from your computer) under any circumstances.

You are reminded to make use of the free demo versions already provided on the website, to fully evaluate stacks for compatibility and suitability before making a purchase.

If you cannot get the free demo version to work, DO NOT proceed with purchasing the stack - because the purchased stack is unlikely to work any better for you. Please request technical assistance first.

Be certain that the stack you are buying is actually the one you want, and that you don't already own it or are confusing it with another stack of similar name or functionality.

This started as a stack purely for getting age verification, for visitors coming to a microbrewery website. However one of our regular customers was in need of a stack that could get users to watch an important instructional video, before allowing them to continue onwards to a software downloads website. This stack already had the basis to do 95% of what he wanted, and with a few further additions, this stack grew into one that can confidently handle almost any sort of basic visitor verification.

VerifiyStack can be used in conjunction with other stacks like CookieManager or MiniCookie, if you need to conditionally keep restricted content entirely removed from webpages, until after the verification test has been passed. So VerifiyStack goes a long way towards compliance of age restricted content.

Nine different verification methods are supported by VerifiyStack:

  1. Soft Verification: Simply asks for the visitor to read something on screen and click on a button.
  2. Audio Listening: The visitor has to listen to a short audio file, before they can continue.
  3. Video Watching: The visitor has to watch a short video clip or advert, before they can continue.
  4. Checkbox Verification: Requires that the visitor checks on a checkbox, for confirmation.
  5. Low Security Password: A bare-basic password system (mostly just for fun) that validates via Javascript.
  6. Full Date Inputs: The visitor has to verify their birth day, month and year using number input boxes.
  7. Year Only Input: The visitor has to type their birth year within a number input box.
  8. Full Date Select Menus: Select menus are presented for the day, month and year, the visitor has to choose from.
  9. Year Only Select Menu: Provides a single select menu for the visitor to select their birth year from.

The entire VerifiyStack stack is translatable into any language. The age threshold (18 by default) can be raised or lowered to suit individual requirements for date verification types.

Within the VerifiyStack settings, the window shade, buttons, input boxes and modal popup are all fully customisable to match an existing website. This ensures that VerifiyStack looks like an expertly-coded solution for your website; rather than something that gives an impression of being crudely added as an afterthought!

We recognise that quite a lot of professional RapidWeaver users running businesses like breweries, pharmaceuticals, gaming and gambling shops are affiliated with various support, abuse and addiction help services. So we provide optional space within the VerifiyStack stack, where you can display associated buttons or links to these outside services, like,,, and etc.

Not only for age verification!

It needs to be emphasised that this stack is not just for age verification. The soft, audio, video and checkbox verification types make this stack perfect for getting users to see or agree to something, before viewing a webpage or being redirected somewhere else (like to a download link). The normal modal title text and message text can be left empty. You can instead use the Additional Content Above or Additional Content Below settings to place extra stacks within your modal window, like free UsefulStacks, to create small boxes of scrolling content.

We are mostly using the default settings for this example. VerifiyStack has lots of settings and may look complicated at first glance, but it is in-fact remarkably simple and flexible to use. The wide choice of settings are there to aid users who want to heavily customise the appearance of the popup modal.

There is also a sample RapidWeaver project file to download from the top of this page. This provides a real working example of each configuration possible. It works with both the free demo version of VerifyStack and the paid version to buy here.


Please follow these instructions for getting a VerifySack configured within your RapidWeaver project:
  1. Once installed into Stacks and RapidWeaver, open your Stacks library and drag-and-drop a copy of the VerifyStack stack into your page.
  2. In the stack settings (shown in Stacks edit mode) choose the type of verification to use. Date verification is the default setting, but other verification types exist too.
  3. Change any of the desired style and colour settings, to match your website. Font faces are already inherited from your theme, for greater design consistency.
  4. Preview your webpage to test the verification. Export or publish when done.

To include VerifyStack on every page of your website (recommended) configure it as a partial. If you are already including stacks on every page (like cookie popups or footers) then you can include VerifiyStack with these too.

Making VerifyStack work with CookieManager or MiniCookie

So the basic concept to understand is that when the verification test is 'passed', a new cookie is set on the visitors computer called passed_verification. This gives us a convenient flag to identify visitors who have gone through our verification test and those who haven't.

Working on the assumption we had some content we only want shown to verified visitors, we can place one or more CookieManager or MiniCookie stacks in the webpage. If either of these stacks is set to Conditional Display, then we have placeholders to put content. We could display content to website users who are not verified yet, and display alternative content to those website users who have passed our verification test.

The key benefit of using CookieManager or MiniCookie stacks for conditional display of content is that it's all done server side with PHP. There is never a danger that the restricted content can still download or be seen in the page background by someone. The restricted content only ever comes into the page, when the verification test has passed.
