New Website


After more than five years, the coli-conc website at got a fresh layout and internal refactoring. All URLs should still be working! (If not, please let us know.) The sources are managed in a public GitHub repository like all of our software. Selected pages are available in both English and German.

Instead of being served through PHP, the website is now built from Markdown files via a static site generator called Eleventy. This made it possible to better separate logic from content. Dynamic elements can be added client side with our favorite JavaScript framework Vue.

This post is also part of our new blog! We converted existing reports to blog posts, so there are already some posts available. We will share updates about the project and our services here from now on. You can subscribe to our blog via RSS and follow us on Twitter.
