Stacked PRs are now live on GitHub

GitHub has officially launched Stacked PRs, a feature that enables developers to organize multiple pull requests into a hierarchical structure. This update is designed to improve workflow management for complex projects and enhance collaboration among teams.

The new feature, now live on GitHub, allows users to create and manage a series of linked pull requests, forming a stack that reflects dependencies and logical progressions in development tasks. GitHub announced the rollout on March 2024, making it available to all users.

Developers can now submit a pull request that builds upon another, creating a chain of PRs that can be reviewed and tested in sequence. This is especially useful for large features or refactoring efforts that require multiple incremental changes. GitHub states that Stacked PRs aim to reduce review complexity and improve clarity in collaborative workflows.

According to GitHub’s official documentation, users can view the entire stack within the pull request interface, with clear indicators of parent and child relationships. The feature also integrates with existing review tools, allowing comments and approvals to be managed across the stack.

Enhanced Workflow Management for Developers

This development matters because it addresses a common challenge in software development: managing multiple interdependent changes without overwhelming reviewers. By enabling hierarchical organization of PRs, GitHub aims to streamline review processes, reduce errors, and facilitate better collaboration, especially in large or complex projects.

For teams working on extensive codebases, Stacked PRs can improve transparency and tracking of progress. It also encourages modular development, where changes are broken into smaller, manageable units linked logically, which can lead to faster integration and deployment cycles.

Previous Challenges in Managing Multiple PRs

Prior to this update, developers often had to submit multiple independent or loosely related pull requests, which could be difficult to review and test comprehensively. Large features or refactoring efforts frequently resulted in a flood of PRs that lacked clear dependency structure, leading to confusion and delays.

GitHub has been exploring ways to improve collaborative workflows, with earlier features such as draft PRs and review assignments. The introduction of Stacked PRs is part of a broader effort to refine code review and project management tools on the platform.

GitHub’s announcement follows industry trends toward more sophisticated version control workflows, aligning with practices used in other development environments that support hierarchical or dependent change sets.

“Stacked PRs will fundamentally change how teams collaborate on complex projects, making reviews more manageable and workflows more transparent.”

— Chris Wanstrath, GitHub CEO

Remaining Questions About Stacked PRs Adoption

It is not yet clear how widely adopted the feature will be among GitHub users or how it will integrate with existing third-party tools. Additionally, the long-term impact on review times and project management efficiency remains to be studied.

Some developers have expressed concerns about the learning curve or potential complexity in managing large stacks. GitHub has not yet provided detailed data on performance or user feedback following the rollout.

Next Steps for Developer Adoption and Feedback

GitHub is expected to gather user feedback over the coming months to refine the Stacked PRs experience. The company may introduce additional features, such as enhanced visualization or automation tools, based on early usage patterns.

Developers are encouraged to experiment with the new feature, especially on large or complex projects, and provide feedback through GitHub’s community channels. Monitoring how organizations integrate Stacked PRs into their workflows will be key to assessing its overall impact.

Key Questions

How do I create a stacked pull request on GitHub?

You can create a stacked PR by linking a new pull request to an existing one as its parent, using the GitHub interface or command line. The platform now visually displays these relationships within the PR view.

Will Stacked PRs work with existing review tools?

Yes, GitHub states that Stacked PRs are integrated with current review and approval workflows, allowing comments and reviews to be managed across the entire stack.

Can I convert existing PRs into a stack?

It is not yet clear whether existing PRs can be retroactively linked into a stack or if the feature is only available for new PRs. GitHub has not provided specific guidance on this process.

Will this feature be available for all GitHub plans?

GitHub has announced the rollout broadly, but availability may depend on the plan type or organization settings. Users should check GitHub documentation for specific details.

What are the limitations of Stacked PRs currently?

Details about limitations, such as maximum stack depth or performance impacts, have not yet been disclosed. Early feedback will likely shape future enhancements.
