This year we successfully ported https://git.kmx.io/ from Elixir (Erlang VM : Beam) to pure C and KC3. The webserver still has problems since we switched from libevent2 to kqueue (see other blog post) but the application runs fine. Git repositories can be managed through a web interface and SSH keys are added to the server configuration files.
The switch was made possible because most of the code was copied as-is from Elixir to KC3. Then from KC3 to C is another challenge but its entirely possible as KC3 is only a C runtime so if you inspect how it works you can devise a C implementation for any large scale Elixir program and reimplement first as a whole to KC3 and then function by function to C.
We also introduced mailing lists in an earlier blog post, please subscribe if you're interested in updates.
