Intro

Source Control has become a rallying point of sorts for me in the last few years. It has saved my bacon on a few occassions and source control in general (and git, specifically) is near and dear to me. I'm always on the quest for the best application development workflow, which can sometimes be difficult to achieve, depending on varying development team sizes.

I've gone through a couple rounds of preferences when it comes to self-hosted source control servers in the past couple years. I'm going to break down what I like about externally hosted solutions and then get into the benefits and trade-offs of a few of the (freely available) self-hosted solutions.

Externally Hosted

There are two major players in the (free) externally hosted realm. There are more, but the two big ones of late are GitHub and Bitbucket.

GitHub

I was going to start with a succinct description of what GitHub is, straight from their page. Oddly enough, there isn't an easy one I could find. They talk a fair amount about enterprise solutions and some sales lingo about enabling teams, so instead I'll drop in the lead paragraph from the Wikipedia page on GitHub:

"GitHub is a web-based Git repository hosting service, which offers all of the distributed revision control and source code management (SCM) functionality of Git as well as adding its own features. Unlike Git, which is strictly a command-line tool, GitHub provides a web-based graphical interface and desktop as well as mobile integration. It also provides access control and several collaboration features such as wikis, task management, and bug tracking and feature requests for every project."

So, now that we've established that GitHub is a git repository server, which provides additional features (issue tracking, wikis, forking, etc.), let's get into some of the differentiating specifics:

only hosts git repositories
any private repos / enterprise hosting costs ðµ
generally the de facto solution for the Open Source community
free static site (or generated via Jekyll) via GitHub Pages (any gh-pages branch for a GitHub repo will have a space at <user>.github.io/<repoName>), like this one (which uses a custom domain now)

I like GitHub, but it's not perfect. There are plenty of upsides due to its popularity though, like Travis CI, which gives CI testing for free to all GitHub repositories, or Gitter which gives "discussions" to GitHub teams and repositories, across Pull Requests and Issues.

Bitbucket

As with GitHub, Bitbucket (from Atlassian) offers repository hosting (for both Git and Mercurial) along with some extras. Here's their description:

"Bitbucket is a web-based hosting service for projects that use either the Mercurial (since launch) or Git (since October 2011) revision control systems."

hosts both Git and Mercurial repositories
free accounts get an unlimited number of public or private repositories
private repositories with a free account can have up to 5 collaborators
additional enterprise hosted options with different products for different aspects of code management (issue tracking with Jira, Stash for self-hosted Bitbucket server, Bamboo for CI, and more); also costing ðµ
strong articles and guides (Atlassian blog)

Atlassian is also the creator of SourceTree, a free Mercurial and Git client for Mac and Windows platforms. SourceTree bakes in the Git/Hg-Flow processes, making it easier to implement feature branching workflows (or others).

Winner?

What are you looking for? I could claim one as superior to the other, and my inclination is that Bitbucket it technically superior, but I believe we're better off for having both. They bring us a lot of goodies in an attempt to gain our business with increasingly better tools. This is a good thing.

Self-Hosting

Why self host? I could a few specific reasons, but ultimately, I've found that self-hosting is really only going to depend on imposed business requirements. Depending on the size of your "shop", this can be a rabbit hole, as you'll see from my experiences with Redmine.

Redmine

Redmine was one of the early kids on the block, is written with Ruby on Rails, and supports Git, Mercurial, SVN, CVS, and others. It works and supports quite possibly the highest number of protocols, but can be a bit cumbersome, especially compared to how easy some of the others are to operate. I set up a Redmine instance at my day job and it's been sufficient, though doesn't always sport things we've grown to expect, like a link to clone (HTTPS or SSH) at the top.

GitLab CE

In all honesty, GitLab very nearly replicates all the beauty and ease of use you would come to expect from GitHub or Bitbucket and is freely available. It's slick. If I hadn't run into trouble, I would still be using it. It's worth a look and I highly recommend extensive backups before upgrading versions. Its biggest potential downside for some is that it's Git-only.

I fell in love with GitLab's Community Edition... after I got it set up the first time, which was before the omnibus package would install correctly on my home Ubuntu box. Eventually, I switched to the omnibus package, but that eventually failed hard for me on an upgrade (via the recommended steps) and I lost my db. I had enough hassling at that point, as you can probably tell from the issue I had open for a while.

Gogs

When I went looking for alternates, I found Gogs, which says it's a "self-hosted Git service written in Go". That's Go as in GoLang, not that that really matters much. Gogs runs rather light and can run on a Raspberry Pi.

I've been using it for a while, and even submitted a PR. I thought it odd that I was directed to a different repo for the PR, but it seems to be a bit of a community effort.

Summary

All in all, if you're looking to go your own way, most of the self-hosted options focus on Git with no real regard for other protocols. If Mercurial is a must, I recommend using a free account with Bitbucket and if your needs change, roll with the punches. As for those of us who have bought into Git, I thoroughly enjoy the simplicity of Gogs, but will admit to being up for a ~~rematch~~ revisit to GitLab, after we've both had our time to see other ~~people~~ solutions.
