    We built a FOSS documentation CMS with a pretty GUI▲165

    Kalmia started as a small hobby project about two months ago, but it quickly evolved when we needed a better solution to manage our office's documentation.

We're excited to see how the community can take it further, contribute, and adapt it to their own needs!

What we call a ‘Pricing Service’, which now holds around 9 million live price points (!!). Then we map these prices to infrastructure code.
