Most of the curl website is also available in a public git repository, although separate from the source code repository since it generally is not interesting to the same people and we can maintain a different list of people that have push rights, etc.

The website git repository is available on GitHub at this URL: and you can clone a copy of the web code like this:

git clone

Building the web

The website is a custom-made setup that mostly builds static HTML files from a set of source files. The source files are preprocessed with what is a souped-up C preprocessor called fcpp and a set of perl scripts. The man pages get converted to HTML with roffit. Make sure fcpp, perl, roffit, make and curl are all in your $PATH.

Once you have cloned the git repository the first time, invoke sh once to get a symlink and some initial local files setup, and then you can build the website locally by invoking make in the source root tree.

Note that this does not make you a complete website mirror, as some scripts and files are only available on the real actual site, but should give you enough to let you view most HTML pages locally.

Run a local clone

The website is built in a way that makes it easy and convenient to host a local copy for browsing and testing changes before we push them to the official site in production. We then recommend you call the site curl.local and add that as an entry in your local /etc/hosts file. Then point the document root of your HTTP server to the curl-www source code root.

Website infrastructure

  • The public curl website is hosted at
  • The domain name is owned by Daniel Stenberg
  • The main origin machine is sponsored by Haxx
  • The domain is served by anycast distributed DNS servers sponsored by Kirei
  • The site is delivered to the world via a CDN run by Fastly
  • The website updates itself from GitHub every N minutes. The CDN front-ends cache content for Y minutes (different types cache content different times)
