Source code is the biggest asset of every development team because it encompasses valuable information about product functionality.

During a software development life cycle (SDLC), many participants have a hand in the source code, modifying the existing and adding new source code.

Because developers work on different parts of software at the same time, their activities are concurrent. Code modifications may conflict with each other and newly added code may introduce bugs. As software evolves, the risk of an error and unplanned consequences grows.

Version control protects the source code from these kinds of issues. Relying on version control systems (VCS), development teams can track all changes in the source code files made by each contributor throughout an entire SDLC.

Gitlab and GitHub are commonly used VCS, which have become an essential part of the daily practice of development teams.

Now, how are GitLab and GitHub connected to Git? As a VCS, Git is at the heart of both GitHub and GitLab.

What is Git? A simple explanation

Before exploring GitHub and GitLab, let’s clarify what Git is. During an SDLC, the source code undergoes multiple changes. New versions of it are created by the development team every day. Just like with video games, in programming, every decision you make can be consequential.

If you make a bad decision, the entire course of the game may go in the wrong direction. How to avoid that? Instead of playing the game all over again, players usually revert to a saved checkpoint and start again from there.

Git is the tool that ensures those checkpoints are in place. During the development process, developers can roll back to the previous version of source code and make changes if needed. Additionally, Git makes it possible for developers to find code added by them or other developers at any point of SDLC.

Thus, Git is a version-control system for tracking changes in the source code during an SDLC. It was initially designed by the Linux creator, Linus Torvalds, in 2005. Version control systems weren’t a new concept. But since then Git took a major leap, becoming the preferred solution for many projects, both commercial and open-source. Today, it’s an open-source, free tool.

Git can be initialized in a project to create a Git repository. After you install Git, you will see that a Git repository is a folder inside a project that contains a history of changes made to files in a project over time.

Git branch

VCS usually have branching support. Creating a Git branch means deviating from the main branch to continue working without making changes in the main branch. The main branch is called “master,” and it’s also known as a lightweight movable pointer to one of the commits.

What is GitHub?

GitHub is a collaboration platform for developers based on the Git version control system. It hosts and reviews code, manages projects, allows remote access to work on code collaboratively in a distributed environment.

GitHub was launched in 2008 by Tom Preston-Werner, Chris Wanstrath, and PJ Hyett. The company was acquired by Microsoft in October, 2018.

Today, GitHub has 26 million users. What is the reason behind its popularity? It’s all about networking. GitHub simplifies work for large software development teams. It allows to collaborate with developers from different parts of the world, plan their work, and track the progress in projects. GitHub also boasts controlled access, bug tracking, task management, and Wiki space.

GitHub was the cause for other version control systems to sink into oblivion. It happened for a reason: The creators of GitHub put a lot of effort into meeting the demands of modern technology teams.

GitHub pricing

GitHub offers pricing plans for individuals and teams based on the number of collaborators. Because the company intends to get a substantial bulk of their profit from collaborating with large companies, the pricing for smaller teams is rather loyal.

  • GitHub free: Users get a free account with unlimited private projects up to three collaborators or public repositories with an unlimited number of collaborators.
  • GitHub Pro for $7 per month: The enhanced free account with an unlimited number of collaborators and advanced tools and insights.
  • GitHub Team for $9 per user per month: Organizations get unlimited public and private repositories with team management and collaboration tools.
  • GitHub Enterprise: The cost is defined for a client company individually and depends on the team size. The plan includes security, compliance, and deployment controls for organizations.

What is GitLab?

GitLab is a web based repository, which in addition to the collaborative capabilities is focused on DevOps and CI/CD. GitLab boasts almost all features GitHub has, allows teams to collaborate on code, and provides project management tools.

GitLab was launched in 2011 by two Ukrainian developers, Dmytro Zaporozhets and Valery Sizov. In 2018, the company raised $100 million in Series D round funding, joining the unicorn club.

Even though the company is relatively young, GitLab open source platform is leveraged by well-known enterprises, including IBM, Sony, NASA, Oracle, Boeing, SpaceX.

GitLab is written in Ruby and Go and includes functions like project planning, source code management, and CI/CD. GitLab has an open source nature, which allows developers to run it on their own servers. For detailed information on how to use GitLab, take a look at GitLab Documents.

GitLab drew a lot of attention after Microsoft had acquired GitHub, as many developers started contemplating moving away from GitHub due to distrust to Microsoft. In 2018, Gitlab was listed among top DevOps tools.

GitLab pricing

  • A free version. Suitable for deployment on your own hosting or server.
  • Bronze for $4 per month per user. This plan suits smaller teams, enabling them to speed up DevOps delivery.
  • Silver for $19 per month per user. This enables organizations to scale up DevOps delivery.
  • Gold for $99 per month per user. It’s an enterprise edition, which enables IT transformation for large organizations, while helping to improve Portfolio Management, Application Security, Compliance, and Operations.

GitLab or GitHub: Which one to choose?

Some say GitLab is the clone of GitHub, but we see it as an enhanced version of it. Both platforms offer free plans, so you can try out each of them to see which one works best for you. Below, we have pulled together key similarities and differences between GitHub and GitLab.



Both systems have great reporting tools about collaborators’ work, including monitor status changes, assigning owners, and bug reporting.

GitHub and GitLab offer features like setting the issue status, assignees, milestones and allows to filter them easily.
