Ask HN: What services do you use alongside GitHub to get “Atlassian” features?

Atlassian has a pretty convenient offering. With a single service you can get:

- Version Control (Bitbucket)

- Issue Tracking (Jira)

- Team Chat (HipChat)

- Wiki (Confluence)

- CI/CD (Bitbucket Pipeline)

- and soon Project Management (Trello).

To construct a similar set of services but centered around GitHub, what would/do you use? Any services for features not listed above?
