GitHub Launches Stacked Pull Requests in Public Preview, But Cross-Fork Stacks Not Supported

tristanbob · x · 2026-08-02

GitHub has introduced Stacked Pull Requests, now in public preview. This feature allows creating a series of interdependent PRs in the same repository, each targeting the branch of the PR below it, forming an ordered chain that lands on a single branch. It enables breaking large PRs into smaller, independently reviewable ones. However, all branches must be in the same repository; cross-fork stacks are not supported, nor is GitHub Desktop. Developer tristanbob encountered this limitation when attempting to create a cross-fork stacked PR.
