I found it very interesting how you highlighted Jenkins' flexibility and its ability to customize through pipelines in Groovy. The comparison with other tools such as CircleCI and TeamCity was clear and well-structured, helping to understand in which cases Jenkins may be the best option.
Something that stood out to me was how you highlighted Jenkins' extensive plugin library, a point I also discussed in my article on TeamCity, but with a different approach, as TeamCity leans more towards an integrated, pre-configured experience.
