Personally I run gitbucket, which is a small and self-contained java-based "github alternative". There are a bunch of these small project/git-hosts, and while they're easy to manage they're less featureful than the gitlab offering. Gitlab does have some great features, such as the whole integrated CI system, built upon runners & docker. The downside is complexity, and resource-usage. I know gitlab is free, and I could install it, but the added resources and potential security issues make it a non-starter.
