What is stacking?

Stacked changes (or "stacked diffs") is a development workflow where you break a large feature into small, focused branches that build on top of each other. Instead of one massive Pull Request, you have a "stack" of smaller PRs.

Why use stacking?

  • Faster Reviews: Reviewers can process small, 50-line PRs much faster than a single 500-line PR
  • Parallel Work: Don't wait for a PR to merge before starting the next part of your feature
  • Incremental Shipping: Parts of a feature can be merged and deployed as they are approved
  • Cleaner History: Each PR represents a logical step in your feature's development

The Stacked Workflow

Stacks naturally form a tree structure—a single branch can have multiple children when you need to work on parallel features. Stackit manages the complexity of this workflow—automatically handling rebases, keeping track of parent-child relationships, and submitting the entire stack to GitHub with a single command.
