Code review is where the magic happens. It’s where bugs get caught, ideas get better, and teams grow stronger. Tools like GitLab make this process smooth and organized. But GitLab is not the only option out there. There are many great tools that help you review, manage, and collaborate on code like a pro.
TLDR: GitLab is great for code review, but it’s not your only choice. Tools like GitHub, Bitbucket, Azure DevOps, Phabricator, Review Board, and Crucible offer strong features for reviewing and managing code. Each tool has unique strengths. Choosing the right one depends on your team size, workflow, and budget.
Let’s explore six powerful code review tools like GitLab. We’ll keep it simple. And maybe even a little fun.
1. GitHub
GitHub is one of the most popular platforms for developers. It’s simple. Clean. And packed with features.
At its core, GitHub offers:
- Pull Requests for code review
- Inline comments on specific lines
- Status checks and CI integration
- Branch protection rules
- Project management boards
Pull requests are the heart of GitHub’s review system. Developers submit changes. Teammates review them. Discussions happen directly in the code. You can suggest changes. Approve them. Or request edits.
Why teams love GitHub:
- Huge community support
- Easy integrations with third-party tools
- Great documentation
- Strong automation with GitHub Actions
GitHub feels polished. It’s ideal for open-source projects and private teams alike.
2. Bitbucket
Bitbucket is Atlassian’s answer to GitHub and GitLab. It plays very nicely with tools like Jira and Trello.
If your team already uses Atlassian products, Bitbucket makes life easier.
Main features include:
- Pull request reviews
- Inline commenting
- Built-in CI CD with Bitbucket Pipelines
- Integration with Jira issues
- Branch permissions
One standout feature is how closely it connects commits to Jira tickets. You can see which task a code change relates to. That makes tracking progress simple.
Bitbucket supports both Git and Mercurial repositories. That flexibility helps teams with older systems.
It’s great for:
- Enterprise teams
- Agile workflows
- Companies already deep into Atlassian tools
3. Azure DevOps
Azure DevOps is Microsoft’s powerful development suite. It’s more than just a code review tool. It’s a full DevOps platform.
It offers:
- Azure Repos for source control
- Pull request workflows
- Automated testing pipelines
- Boards for project tracking
- Advanced security features
Its pull request system works much like GitLab’s. You can:
- Add required reviewers
- Leave inline feedback
- Enforce approval policies
- Run automated checks before merging
Azure DevOps shines in enterprise environments. Especially those already using Microsoft tools like Visual Studio and Azure Cloud.
It can feel a bit heavy for small teams. But for larger organizations, it’s incredibly powerful.
4. Phabricator
Phabricator is an open-source tool built with code review at its core. It’s flexible. Highly customizable. And developer-focused.
Its code review tool is called Differential.
Key features include:
- Detailed inline comments
- File and line-level review
- Reviewer assignment
- Audit trails
- Integration with Git, Mercurial, and SVN
One thing that makes Phabricator special is its strong focus on pre-commit reviews. Developers can submit patches before merging anything.
That reduces broken builds. And messy main branches.
Phabricator also includes:
- Task management
- Wiki documentation
- Bug tracking
It gives you lots of control. But it may require more setup and maintenance than cloud-based tools.
5. Review Board
Review Board is built specifically for code review. It’s simple. Focused. And effective.
If you want something lightweight without extra project management layers, this might be your tool.
Main features:
- Side by side diffs
- Inline commenting
- Email notifications
- Multi repository support
- Workflow customization
Review Board supports many version control systems. That flexibility makes it useful for teams with mixed setups.
What makes it appealing:
- Clean interface
- Focused on reviewing only
- Flexible review workflows
But remember. It doesn’t offer the full DevOps pipeline like GitLab or Azure DevOps. It sticks to what it does best.
6. Crucible
Crucible is another Atlassian product. It’s designed purely for code review.
Unlike Bitbucket, Crucible can review:
- Git repositories
- SVN repositories
- Perforce repositories
Core features:
- Peer code reviews
- Inline comments
- Review statistics
- Audit logs
- Workflow tracking
One standout feature is its review metrics. Managers can see review time, defect rates, and participation levels.
It helps improve not just the code. But the team’s habits.
Crucible works best for teams that need structured, formal review processes.
Quick Comparison Chart
| Tool | Best For | Built In CI CD | Project Management | Open Source Option |
|---|---|---|---|---|
| GitHub | General use, open source projects | Yes | Basic boards | Partial |
| Bitbucket | Atlassian ecosystem teams | Yes | Strong with Jira | No |
| Azure DevOps | Enterprise Microsoft environments | Yes | Advanced boards | No |
| Phabricator | Custom setups, developer heavy teams | No | Yes | Yes |
| Review Board | Focused code reviews | No | Limited | Yes |
| Crucible | Formal structured reviews | No | No | No |
How To Choose The Right Tool
Not every tool fits every team. Ask yourself a few simple questions:
- Do we need full DevOps features?
- Are we already using a specific ecosystem?
- Is budget a concern?
- Do we prefer cloud or self hosted?
- How formal is our review process?
If you want everything in one place, tools like GitHub, GitLab, and Azure DevOps are solid choices.
If you only care about reviews, Review Board or Crucible might be enough.
If customization and open source matter most, Phabricator stands out.
Why Code Review Tools Matter So Much
Let’s zoom out for a second.
Code review is not just about catching bugs. It’s about:
- Learning from each other
- Keeping coding standards consistent
- Preventing security issues
- Building team trust
A good tool makes this process smooth. It reduces friction. It keeps conversations inside the code. And it creates a clear history of decisions.
Without the right tool, reviews can feel chaotic. With the right one, they feel natural and even enjoyable.
Final Thoughts
GitLab is fantastic. But it’s not alone.
From GitHub’s massive ecosystem to Azure DevOps’ enterprise strength, from the simplicity of Review Board to the structure of Crucible, there’s something for every team.
The key is simple.
Pick the tool that fits your workflow. Not the one that’s just popular.
Good code deserves good review. And the right platform can make all the difference.
