Stacked Diffs Workflow

Purpose

Stacked diffs (also known as stacked PRs or stacked branches) is a code review workflow pioneered at Meta (Facebook) that enables:

• Breaking large changes into small, reviewable chunks
• Parallel code review of dependent changes
• Faster iteration without waiting for reviews
• Cleaner git history with logical commits
• Reduced context switching for reviewers

Meta engineers use stacked diffs extensively with their internal tools, and this practice has spread to companies like Uber, Airbnb, and many others.
