Stacking.dev is an educational and conceptual platform centered around the “stacked pull request” (or stacked diffs) workflow in software development. It introduces and explains a modern Git-based development approach where large changes are broken into smaller, dependent pull requests that are reviewed and merged in sequence.

The core idea behind stacking is to improve developer productivity by removing the traditional bottleneck of sequential code review. Instead of waiting for a single large pull request to be approved before continuing work, developers can create multiple layered changes that build on each other. This allows teams to work in parallel, reduce review complexity, and ship features faster.

Stacking.dev explains both the benefits and challenges of this approach, including improved review speed, better code organization, and more maintainable change sets, while also addressing the added complexity of managing dependent branches and rebasing stacks.

The site also acts as a guide to tooling in this ecosystem, highlighting tools like Graphite and other Git-based utilities that help automate stack management, synchronize changes, and reduce the manual overhead of maintaining dependent pull requests.

Overall, stacking.dev serves as an entry point for developers and teams looking to adopt a more scalable and efficient Git workflow inspired by practices used in high-performance engineering organizations.

Key features include:

• Explanation of stacked pull request workflows
• Guides on improving Git and code review processes
• Insights into reducing code review bottlenecks
• Overview of tools that support stacking (e.g., Graphite, ghstack)
• Educational diagrams and workflow comparisons

Common use cases include:

• Learning modern Git workflows
• Improving engineering team productivity
• Optimizing code review cycles
• Reducing pull request size and complexity
• Adopting stacked development practices in software teams

Stacking.dev is an independent educational resource focused on developer workflow optimization and Git best practices.
