TL;DR
GitHub has rolled out the long-anticipated stacked pull requests feature, enabling developers to organize related PRs into a stack. This new capability aims to improve workflow management and collaboration for open-source and enterprise projects.
GitHub has officially launched the stacked pull requests feature, enabling developers to organize related pull requests into a hierarchical stack. This new functionality, now live for all users, aims to streamline complex code reviews and improve collaboration workflows.
The stacked PRs feature allows users to create a series of dependent pull requests that are visually grouped and linked, making it easier to review large or multi-part changes. GitHub announced the feature in early October 2023, and it is now accessible via the web interface and API.
According to GitHub’s official documentation, the feature is designed to help teams manage complex developments, such as large refactors or features that require multiple incremental PRs. Developers can now create a parent PR with multiple child PRs, each representing a distinct step in the development process.
GitHub representatives confirmed that the rollout is complete and that the feature is available to all users, including open-source contributors and enterprise accounts. The company stated that the feature aims to reduce the clutter of multiple open PRs and improve review efficiency.
Implications for Developer Workflow and Collaboration
The introduction of stacked PRs is significant because it addresses a longstanding challenge in software development: managing complex, multi-part changes. By visually linking related PRs, teams can better understand dependencies, reduce review confusion, and accelerate integration cycles.
This feature could lead to more structured development processes, especially in large projects with many contributors. It also aligns with GitHub’s broader goal of enhancing collaboration and code review efficiency, which are critical in open-source and enterprise environments.

Previous Efforts to Improve PR Management
Prior to this launch, developers relied on workarounds such as referencing related PRs in descriptions or using external tools to track dependencies. GitHub had hinted at this feature in various developer forums and during its annual product updates, but it was not officially available until October 2023.
The concept of linked or dependent PRs has been a common request among users, especially those working on large-scale projects. Some third-party tools attempted to fill this gap, but a native, integrated solution was widely considered necessary for better workflow management.
“Stacked PRs will fundamentally change how teams collaborate on complex code changes, making reviews more manageable and transparent.”

Remaining Questions About Stacked PRs Functionality
It is not yet clear how the feature will perform at scale in very large projects or how it will integrate with existing third-party tools. Details about user customization options and potential limitations are still emerging, and some users have expressed concerns about workflow changes.
Additionally, the long-term impact on review times and project management efficiency remains to be studied through broader adoption.

Next Steps for Adoption and Feedback
GitHub is expected to monitor user feedback closely and may introduce improvements or additional features based on early usage. Developers are encouraged to adopt the feature and share their experiences, which could influence future updates.
In the coming months, GitHub might also expand the functionality, such as adding more visualization options or integrating with other project management tools.

Key Questions
How do I create a stacked PR on GitHub?
You can create a stacked PR by starting with a parent PR and then linking subsequent dependent PRs through the GitHub interface or API, following the instructions in the official documentation.
Is the feature available for all GitHub users?
Yes, the stacked PRs feature has been rolled out to all users, including open-source contributors and enterprise accounts, as of October 2023.
Will this replace existing methods of managing multiple PRs?
It aims to complement existing workflows by providing a native, visual way to organize related PRs. Users can still reference PRs manually or use external tools, but stacked PRs offer a more integrated solution.
Are there any known limitations or bugs?
As with any new feature, some limitations or bugs may be reported as users begin to adopt it at scale. GitHub has stated that ongoing improvements are planned based on user feedback.
What is the expected impact on code review times?
While early feedback suggests the feature may streamline reviews for complex changes, definitive data on review times will be available after broader adoption.
