Gitea[0] is a pleasant, easy-to-set-up 'GitHub lite', if you are looking for something more turnkey and less custom:

  - users/organizations
  - issues
  - PRs
  - milestones
  - releases
  - wikis
  - activity/contrib graphs

I have it running on a $5/mo Linode instance for some of my personal projects.
