Daniel Stenberg <a href="https://daniel.haxx.se/blog/2026/11/11/30-years-of-internet-transfers-with-curl/">reflects</a> on the 30th anniversary of the curl project. <p> <blockquote class="bq"> libcurl runs in an estimated thirty billion installations today. It is a rough estimate since the majority of all libcurl users never tell us they use it, but we need to find it mentioned in their credit screens, open source license windows or their manuals. A super popular app might use libcurl today and not tomorrow, or vice versa, which can make the numbers shift by several billions overnight. In reality of course, once the pulse raise has calmed down and your ego is content, these numbers do not matter. In our corner of the world, things don't change notably when we go from a thousand installs to billions. We still work with similar people, in similar ways, with similar challenges. </blockquote>
