Since I installed Gogs recently, I was actively looking for an answer to "is it written in Go?" first of all. I like how easy it is to just bind service to localhost:someport and add one line for reverse proxy to nginx/caddy/apache/whatever, instead of dealing with all those CGI/FastCGI/WSGI/paths/permisions/indexes/whatever. The second thing I look for is "does it require MySQL or can I just make it create its own SQLite database and stop nagging me about configuration?".
Btw, I have never wrote go besides playing around with web server tutorial recently.
If only someone can recommend me a chat service that is just as easy to configure as Gogs. Mattermost requires its own domain :(
