Complete list of sites to @include / @match into my script?

Question

This question aims to serve as a reference list of all current Stack Exchange sites for use in scripts.

Answer 1

You don't need to support alias domains. They redirect to *.stackexchange.com domains, anyway.

This will match all current Stack Exchange sites. It uses @match for smarter domain and path wildcards. @match also works better for Chrome:

// @match *://*.askubuntu.com/* // @match *://*.mathoverflow.net/* // @match *://*.serverfault.com/* // @match *://*.stackapps.com/* // @match *://*.stackexchange.com/* // @match *://*.stackoverflow.com/* // @match *://*.superuser.com/*

Although, for slightly better speed and to help avoid unexpected results, you should also exclude some sites (Namely: The API, the main blogs¹, SEDE, and the "all sites" pages) unless you are specifically coding for them. Their structure and purpose is markedly different.

So use:

// @match *://*.askubuntu.com/* // @match *://*.mathoverflow.net/* // @match *://*.serverfault.com/* // @match *://*.stackapps.com/* // @match *://*.stackexchange.com/* // @match *://*.stackoverflow.com/* // @match *://*.superuser.com/* // @exclude *://api.stackexchange.com/* // @exclude *://blog.*.com/* // @exclude *://chat.*.com/* // @exclude *://data.stackexchange.com/* // @exclude *://elections.stackexchange.com/* // @exclude *://openid.stackexchange.com/* // @exclude *://stackexchange.com/* 

As a practical start for most scripts.

Note that onstartups no longer needs to be supported.

¹ The "not so main" blogs are all/mostly on a separate domain: blogoverflow.com.
