GitLab vs TeamCity: What are the differences?
GitLab and TeamCity are both popular tools used in software development to manage version control and automate build processes. Let's explore the key differences between them.
Hosting: GitLab is a self-hosted solution that allows users to install and manage it on their own server infrastructure. On the other hand, TeamCity is a commercial software that needs to be installed on a separate server and requires licensing.
Built-in CI/CD: GitLab includes built-in continuous integration and continuous deployment functionalities. It provides a comprehensive solution for managing code, running tests, and deploying applications, all within the same platform. In contrast, TeamCity is a standalone continuous integration server that does not have built-in support for continuous deployment.
Scalability: GitLab is known for its ability to scale and handle large projects with thousands of contributors. It provides high availability, horizontal scalability, and performance optimization features. On the other hand, TeamCity may face challenges when scaling to handle a large number of projects or users.
Integration: GitLab has a wide range of integrations with other tools commonly used in software development, such as Slack, JIRA, and Docker. It also has its own marketplace for extensions and integrations. TeamCity, on the other hand, has fewer integrations available out of the box and may require additional customizations for specific integrations.
Pricing: GitLab offers both a free Community Edition for open-source projects and a paid Enterprise Edition for commercial use. The pricing for GitLab is based on the number of users. On the other hand, TeamCity is a commercial product that requires a license, and the pricing is based on the number of build agents and build configurations.
User Interface: GitLab has a more modern and visually appealing user interface compared to TeamCity. It provides an intuitive and user-friendly experience for managing repositories, branches, and pipelines. TeamCity, while functional, has a slightly outdated interface and may require additional effort for customization and configuration.
In summary, GitLab offers self-hosting, built-in CI/CD, scalability, wide integration options, and a free Community Edition. On the other hand, TeamCity requires separate hosting, lacks built-in continuous deployment, may face scalability challenges, has limited integrations, requires licensing, and has a slightly outdated user interface.
Do you review your Pull/Merge Request before assigning Reviewers?
If you work in a team opening a Pull Request (or Merge Request) looks appropriate. However, have you ever thought about opening a Pull/Merge Request when working by yourself? Here's a checklist of things you can review in your own:
- Pick the correct target branch
- Make Drafts explicit
- Name things properly
- Ask help for tools
- Remove the noise
- Fetch necessary data
- Understand Mergeability
- Pass the message
- Add screenshots
- Be found in the future
- Comment inline in your changes
Read the blog post for more detailed explanation for each item :D
What else do you review before asking for code review?
Using an inclusive language is crucial for fostering a diverse culture. Git has changed the naming conventions to be more language-inclusive, and so you should change. Our development tools, like GitHub and GitLab, already supports the change.
SourceLevel deals very nicely with repositories that changed the master branch to a more appropriate word. Besides, you can use the grep linter the look for exclusive terms contained in the source code.
As the inclusive language gap may happen in other aspects of our lives, have you already thought about them?
One of the magic tricks git performs is the ability to rewrite log history. You can do it in many ways, but git rebase -i
is the one I most use. With this command, It’s possible to switch commits order, remove a commit, squash two or more commits, or edit, for instance.
It’s particularly useful to run it before opening a pull request. It allows developers to “clean up” the mess and organize commits before submitting to review. If you follow the practice 3 and 4, then the list of commits should look very similar to a task list. It should reveal the rationale you had, telling the story of how you end up with that final code.
Out of most of the VCS solutions out there, we found Gitlab was the most feature complete with a free community edition. Their DevSecops offering is also a very robust solution. Gitlab CI/CD was quite easy to setup and the direct integration with your VCS + CI/CD is also a bonus. Out of the box integration with major cloud providers, alerting through instant messages etc. are all extremely convenient. We push our CI/CD updates to MS Teams.
Gitlab as A LOT of features that GitHub and Azure DevOps are missing. Even if both GH and Azure are backed by Microsoft, GitLab being open source has a faster upgrade rate and the hosted by gitlab.com solution seems more appealing than anything else! Quick win: the UI is way better and the Pipeline is way easier to setup on GitLab!
At DeployPlace we use self-hosted GitLab, we have chosen GitLab as most of us are familiar with it. We are happy with all features GitLab provides, I can’t imagine our life without integrated GitLab CI. Another important feature for us is integrated code review tool, we use it every day, we use merge requests, code reviews, branching. To be honest, most of us have GitHub accounts as well, we like to contribute in open source, and we want to be a part of the tech community, but lack of solutions from GitHub in the area of CI doesn’t let us chose it for our projects.
