Two more means to put your website on climate strike

Sebastian Greger

While my own solution is specific to Kirby CMS, two great alternatives for self-hosted “website strike” banners have been shared - both great options to join the #globalclimatestrike with privacy-friendly, technically independent solutions:

A Wordpress plugin

“Webrocker” Tom created a port of the CMS-router-based solution to Wordpress; a simple plugin that even takes into account caching and features configuration settings.

Just as with the Kirby solution, the CMS is going to return HTTP error 503 and a simple banner page for any but manually excepted page requests on 20 September.

Self-hosting the “official” banner

Meanwhile, Matthias Ott shared a pragmatic solution for avoiding to introduce third-party dependencies to his site while using the advanced banner solution from he created local copies of the JavaScript-widget and banner page - making full use of the designed experience while keeping all requests local.

To replicate this solution, incl. disabling the Google tracker:

  • Save and copy index.html, the logo and widget.js into a folder on your server, e.g. /climate-strike/.
  • Then save and copy katwijk-mono-bold-web.woff2 and greve-800-web.woff2 into subfolder /fonts/ of that folder.
  • Lastly include the following HTML near the bottom of your website template, replacing PATH with the URL of the folder with the cloned files:
    <script type="text/javascript">
          disableGoogleAnalytics: true
    <script src="https://PATH/widget.js" async></script>

My personal preference is on the server-side solution, while the banner widget is admittedly more refined (and creates awareness in the run-up to the event). Ultimately, all of these are just means to an end - if you want to join the global climate strike on the web, choose whatever works best for you!


  1. has in the meantime released their own Wordpress plugin as well, but it loads the banner remotely and by default contains a Google Analytics tracker unless manually disabled.
  2. Instructions for self-hosting have since been added to the official code repository as well, but those require experience with, and use of, Git repositories.
