File-based, license-purchased CMS for developers that stores content as flat text files instead of a database.

Kirby is a flat-file content management system published by a German company registered in Neckargemünd, Germany. It has no database dependency — content is stored as plain text files in a folder structure — and is aimed at developers who want full template control.

Unlike SaaS CMS products, Kirby is sold as a one-time or per-project license rather than a subscription, and the team is fully self-funded with no outside investors.

Kirby is sometimes assumed to be Swiss because of its branding, but its registered legal entity and address are in Germany, confirmed via its own legal notice and the German commercial register.
