GitHub vs GitLab vs BitBucket: Key Differences & Feature Comparison

In this comparison, we look at GitHub, GitLab, and BitBucket—and help you find the best tool for code reviews & collaborative coding.

GitHub, GitLab, and BitBucket are three of the leading web-based Git repository services.

At the end of the day, they all kind of offer the same thing and play an active role in most developers tech stacks and toolkits:

• Version control system
• Codebase storage
• Built-in security
• AI-based code writing co-piloting
• Active communities of other developers and open-source projects

So what’s the difference, exactly? Let’s dive in and find out.

GitHub vs. GitLab vs. BitBucket: What’s the difference?

GitHub, GitLab, and BitBucket are the three most popular Git repository services, known for their version control, security, and supportive communities.

GitHub is the most popular, with an active community of 100 million developers. It hosts over 420 million repositories, making it a favorite for open-source projects, with 28 million public repositories. It also provides robust CI/CD pipelines.

GitLab is similar, providing hosting for code repositories. It provides a broader range of DevOps tools than its competitors, including security testing and monitoring.

BitBucket is more specialized. It’s the native Git tool in Atlassian’s Open DevOps solution. It’s primarily a code repository, tailored for Jira and Confluence integrations and software projects.

Now, let’s see how they compare.

1. GitHub

GitHub lets developers host and review code, collaborate on projects, and track changes over time.

The platform has a large community and offers plenty of tools to enhance developer efficiency:

• Repository management and hosting
• Code review and code management
• Issue tracker
• Integrated CI/CD and automation tools such as Jenkins, Travis CI, CircleCI, and more

Key features include GitHub Copilot X, an AI pair programmer that keeps GitHub at the forefront of development.

Owned by Microsoft, it integrates well with Microsoft platforms like Azure, and also supports connections with AWS and other services.

The main difference: Large community and easy-to-use

GitHub's large, active community of over 100 million developers and its user-friendliness are key to its popularity.

GitHub is ideal for open-source projects, remote teams, and collaborative development with both outsourced and in-house teams.

And if you need some help using GitHub? Chances are, there’s a wiki, forum, tutorial, or solution to your problem on GitHub, or a link to an answer on Reddit.

Even if you can’t find an answer, GitHub provides support, and there are millions of other devs you can ask on the platform.

What does GitHub offer that GitLab and BitBucket don’t?

GitHub offers an extensive range of features that other platforms don’t. Such as:

• GitHub Issues: project management tools are included alongside code repositories, including issue tracking.
• Pull request review process: allows product managers and leaders to effectively monitor pull requests.
• GitHub Actions: automate your build, test, and deployment workflows using secure CI/CD features.
• Social features: engage with followers, collaborate on code, and stay connected through notifications. Participate in a vibrant dev community.
• Extensive wikis for every public and private codebase so that it’s easy to document and collaborate on projects.
• Project milestones: make collaboration easier with project milestones that align with your product roadmap.
• DevOps and DevSecOps tools for developers who need full-stack solutions.
• GitHub Copilot X, an AI pair programmer using OpenAI’s GPT-4, helps developers code faster, support pull requests, and integrate AI in development, boosting task completion by 55%.
• Advanced security: make apps and products more secure with GitHub Advanced Security, which scans your code for vulnerabilities.

GitHub Pricing

GitHub pricing starts free, with premium tiers from $4/mo per user (Team) to $21/mo per user for the Enterprise version (which includes self-hosted repos).

The free plan is great for open-source projects, offering unlimited public/private repositories accessible via the web version or command line.

2. GitLab

GitLab is a popular code repository platform with a comprehensive set of DevOps tools.

It was originally launched as a GitHub alternative.

The main difference: A comprehensive suite of DevOps tools

While the other platforms do offer DevOps tools, this is what GitLab is known for.

It excels in integrating security throughout the software development lifecycle.

What does GitLab offer that GitHub and BitBucket don’t?

• Automation: for developers that includes planning to governance and every step in between.
• GitLab Duo: an AI-powered code assistant that helps developers write code faster with fewer errors.
• Custom workflows: tailor a project management system in GitLab to fit your internal processes.
• Scalability: can handle enterprise-level dev cycles, DevSecOps, DevOps, security, and deployments.
• Container registry: manage your software containers and their code.
• Code review: get a comprehensive view of your code, ongoing work, and maintain a robust CI/CD pipeline.‍
• Customizable issue tracking and PM tools: manage projects directly in GitLab or integrate with existing PM and bug tracking tools.‍
• Security scanning: ensure your code is secure both pre- and post-deployment, protecting your products from vulnerabilities.

GitLab Pricing

GitLab pricing starts free, with premium tiers from $29/mo (Premium) to $99/mo per user (Ultimate).

For open-source projects, GitLab offers free Ultimate licenses, along with 50K compute credits/month.

This is for qualifying open-source projects, education institutions, or startups.

3. BitBucket

BitBucket integrates seamlessly with Atlassian products like Jira and Confluence.

It’s built by Atlassian, so it’s somewhat different from the other platforms in this article.

The main difference: Powerful integrations with Jira & Confluence

One of the main reasons for using BitBucket is the integrations with Jira, Confluence, Trello, and other Atlassian products.

If your team is already using Atlassian products or developing software that integrates with them, then BitBucket serves well as a code repository solution.

What does BitBucket offer that GitHub and GitLab don’t?

Other features that BitBucket has that the others don’t include:

• Integrated issue tracking and project management solutions, natively compatible with Jira.
• Native support for Mercurial, while GitHub & GitLab only support Git.
• Private code repositories (similar to the others, but Atlassian-focused).
• Code insights: provide team members with detailed visibility into code quality through performance metrics and analytics.
• Advanced branch permissions for code review and greater security.

BitBucket Pricing

BitBucket offers a very limited free option, with pricing from $15/mo for 1 user.

Pricing depends on team size, with a team of 15 paying $45/mo on the Standard plan or $60 on the Premium.

Atlassian offers free community and academic subscriptions, though they are less extensive than those of GitHub or BitBucket, so it's probably not ideal for open-source projects.

GitHub vs GitLab vs. BitBucket: Comparison Table

Which tool should you choose: GitHub vs. GitLab vs. BitBucket?

For an intuitive UI and ease of use, as well as a large community, GitHub beats the others hands down.

For DevSecOps teams, GitLab has the widest and most robust suite of tools. It has a medium-sized community but is not anywhere near as active as GitHub.

BitBucket is useful for those who either need extensive Jira or Confluence integrations or are developing software specifically for the Atlassian ecosystem.

With all three, repository hosting can either be via the platform or self-hosted.

For most use cases, whether open-source or commercial, GitHub is the clear winner.
