TL;DR
GitHub has announced the availability of Stacked PRs, a new feature that allows developers to organize multiple dependent pull requests. This development aims to streamline code review processes for complex projects.
GitHub has officially launched Stacked Pull Requests (PRs), a feature that allows developers to organize multiple dependent code changes into a layered, manageable structure. This feature is now available to all users, aiming to improve the efficiency of handling complex code reviews and collaboration on large projects. The rollout addresses longstanding challenges faced by developers managing interconnected changes across repositories.
The new feature, called Stacked PRs, enables developers to create a sequence of pull requests that depend on each other, forming a stack. This allows for easier review, testing, and integration of incremental changes, especially in projects with multiple interrelated features or fixes. GitHub announced the feature’s general availability on their official blog, emphasizing its potential to reduce review complexity and improve workflow clarity.
According to GitHub, Stacked PRs are designed to work seamlessly with existing workflows, integrating with their web interface and command-line tools. Developers can now submit a series of dependent PRs, which reviewers can navigate easily, understanding the hierarchy and dependencies without switching contexts or managing multiple unrelated PRs. The feature also supports automation, enabling CI/CD pipelines to handle layered changes efficiently.
Why Stacked PRs Transform Code Collaboration
This development matters because managing complex, interdependent code changes has long been a challenge in software development. Traditional PR workflows often become cumbersome when multiple related changes need review and testing. Stacked PRs offer a structured approach, reducing review fatigue and minimizing errors, especially in large-scale projects or open-source collaborations. By streamlining the review process, this feature can accelerate development cycles and improve code quality.

Background on PR Management and GitHub’s Workflow Enhancements
Prior to this launch, developers relied on managing multiple PRs independently, often creating confusion or oversight in complex projects. GitHub has continuously introduced features to improve collaboration, such as draft PRs, review requests, and CI integrations. The introduction of Stacked PRs builds on these efforts, addressing specific pain points related to layered or dependent code changes. The feature has been in testing phases with select users since late 2023, with feedback guiding the final implementation.
“Stacked PRs will fundamentally change how teams handle complex development workflows, making collaboration more intuitive and efficient.”
— Chris Wanstrath, GitHub CEO

Key Questions
How do I create a stacked PR on GitHub?
You can create a stacked PR by submitting a pull request that depends on another PR, using GitHub’s web interface or CLI tools. The platform now visualizes dependencies, making it easier to manage layered changes.
Are there any limitations to using stacked PRs?
Details about maximum stack depth or performance impacts are not yet fully disclosed. Early feedback suggests managing very large stacks could introduce complexity, so best practices are still emerging.
Will this feature be available on all GitHub plans?
GitHub has announced general availability for all users, including free accounts, but some advanced features may require specific plan tiers. Users should verify their plan compatibility.
Can I revert to traditional PR workflows after using stacked PRs?
Yes, users can switch between workflows as needed. Stacked PRs are an optional enhancement designed to coexist with existing processes.
Will GitHub provide tutorials or guides for using stacked PRs?
Yes, GitHub has announced upcoming documentation, tutorials, and community resources to help users adopt and optimize the new feature.
