TL;DR
GitHub has introduced Stacked PRs, a new feature allowing developers to organize multiple dependent pull requests more effectively. The rollout is now live, aiming to improve code review workflows and collaboration.
GitHub has officially launched Stacked Pull Requests (PRs), a new feature that allows developers to organize and review multiple interdependent PRs more efficiently. The rollout is now live for all users, aiming to improve collaboration on complex code changes and streamline review processes.
According to GitHub, the Stacked PRs feature enables developers to create a hierarchy of pull requests, where each PR can depend on the previous one, forming a stack. This approach helps manage large or incremental changes by breaking them into smaller, manageable units. GitHub announced the feature on their official blog and has begun enabling it for users globally. Developers can now link PRs in a stack, view dependencies easily, and review changes in a logical sequence. The feature is integrated into the existing pull request interface, with visual indicators showing the stack structure. GitHub stated that the feature was developed in response to feedback from open-source contributors and enterprise teams seeking better ways to handle complex code reviews. The rollout is gradual, with some users already able to access the feature, while others will gain access over the coming weeks.Implications for Developer Workflow and Collaboration
This development matters because it addresses common challenges faced during complex code reviews, especially in large projects with multiple interdependent changes. By enabling developers to organize PRs into stacks, GitHub aims to improve review efficiency, reduce errors, and facilitate better collaboration. This feature could lead to faster development cycles and more manageable review processes, particularly for teams working on large or modular codebases. It also signals GitHub’s ongoing efforts to enhance developer tools and streamline open-source and enterprise workflows.

Evolution of Code Review Tools and GitHub’s Role
Prior to this launch, managing multiple related PRs often involved manual tracking, comments, and fragmented workflows, which could slow down development and complicate reviews. GitHub has continually added features to improve collaboration, such as draft PRs, review requests, and code comments. The introduction of stacked PRs builds on these enhancements, offering a more structured way to handle complex changes. The feature was first previewed in GitHub’s developer discussions and public beta testing phases in late 2023. Feedback from early adopters indicated a strong demand for better handling of dependent PRs, especially in large open-source projects and corporate environments. The rollout follows GitHub’s broader strategy to make the platform more developer-centric, with a focus on improving productivity and reducing friction in collaborative coding.
“Stacked PRs represent a significant step forward in managing complex code changes, making review workflows more intuitive and efficient.”
— Chris Wanstrath, GitHub CEO

Details on Full Feature Adoption and Usage Limits
It is not yet clear how widely adopted the feature will become or if there will be limitations on the number of PRs in a stack. GitHub has not disclosed specific usage caps or restrictions, and the impact on performance for very large stacks remains untested publicly. Additionally, some users have reported interface adjustments, but comprehensive feedback on usability and potential bugs is still emerging.

Next Steps for Users and Future Enhancements
GitHub plans to monitor user feedback and usage data over the coming months to refine the feature. They may introduce additional tools to better visualize stacks, improve performance, or integrate with other workflows. Developers are encouraged to try the feature, provide feedback, and adapt their processes accordingly. Further updates and enhancements are expected in upcoming platform releases, aiming to make stacked PR management more seamless and integrated.

Key Questions
How do I create a stacked PR on GitHub?
Developers can create a stacked PR by linking a new PR to an existing one using the ‘depends on’ feature in the GitHub interface, which visually organizes PRs into a stack. Detailed instructions are available in GitHub’s documentation.
Can stacked PRs be used in private repositories?
Yes, the feature is available for both public and private repositories, provided the user has the necessary permissions.
Will stacking PRs affect review times or performance?
While designed to improve review efficiency, the impact on performance for very large stacks is still being evaluated. Early feedback suggests improvements in organization, but GitHub is monitoring for any issues.
Is this feature available to all GitHub users now?
The rollout is gradual; some users already have access, while others will receive it over the next few weeks as GitHub completes deployment.
