Collaboration Tool

I am looking for a project management solution that has git management built in. GitLab seems to be a lot of bloat, but maybe I am just not seeing the benefits of all of it yet. I am not sure if there is a tool that exists; I see Jira with BitBucket integration, but are there any other options? I'd prefer open source, but I'm open to ideas. Thanks. I'd prefer a simple, agile-based approach with kanban board, ticket tracking and git management.

Edit: I am self-hosting on an Unraid server.

Any help or suggestions are welcome.
