Since you just wanted to create a repo, there is no need of third party apps. You can directly send a post request to gitlab API which will create repo.
Go to account tab in your profile, you will find a private token. Copy that.
Now open terminal and run this command with private token (say foo) and your repo name (say bar).
curl -H "Content-Type:application/json" https://gitlab.com/api/v4/projects?private_token=foo -d "{ \"name\": \"bar\" }"For convenience, you can create a shell script, if you don't want to run this command every time.
#!/bin/shcurl -H "Content-Type:application/json" https://gitlab.com/api/v4/projects?private_token=foo -d "{ \"name\": \"$1\" }"Save this to a file gcr.sh and make it executable using chmod +x gcr.sh.
Now to create a repo name bar, run
$ ./gcr.sh bar
