Looks like the number of platforms in the sidebar box ("29") and the number of platforms in the list on §libcurl (~34) don't really align, unless *BSD are counted only as one platform. A little confusing, but certainly not a major nitpick.

Do take care, as an admin knowing that you had edited the curl article might consider that a “conflict of interest” edit under the rules. It would be a good idea to disclose your connection to the project. en.wikipedia.org/wiki/Wikipedi…

Looks good. I see a reference error at the bottom of the page though: "Cite error: A list-defined reference named "Stenberg, GitHub, 2019" is not used in the content (see the help page)."
