GitHub Pages has long been a popular way for developers to host static websites directly from a repository. Over time, the way repositories manage and publish these sites has evolved considerably. This article examines the historical use of the gh-pages branch, how it was traditionally managed, the changes that have taken place, and the reasoning behind the shift toward current best practices.
In the early days of GitHub Pages, using a dedicated branch—commonly named gh-pages—was the standard method to host a static website. The main motivations for this approach were:
- Separation of Concerns: Developers could maintain the source code in the primary branch (e.g.,
masteror latermain) while the rendered static website resided in a separate branch. This separation made it easier to manage website content independently from application code. - Simplified Publishing: By pushing changes to the gh-pages branch, GitHub’s infrastructure would automatically recognize and serve the static files at a predetermined URL (e.g.,
https://<username>.github.io/<repository-name>/). - Dedicated Workflow: Projects that used static site generators (like Jekyll) often output their generated files to the gh-pages branch. This allowed the repository to contain both the source (e.g., Markdown or templates) and the built site, while keeping the published content distinct from the working codebase.
This method quickly became popular because it leveraged Git’s branching model to provide a clean division between development and deployment workflows. Developers appreciated that it allowed them to experiment in the primary branch without risking accidental public exposure of in-progress work.

Historically, using the gh-pages branch involved a few key steps:
- Building the Site: Developers would use a static site generator (or even manual HTML/CSS/JavaScript edits) in their main branch.
- Deploying to gh-pages: After generating the site, the built static files would be committed and pushed to the gh-pages branch. Often, this process was automated via scripts or CI/CD pipelines.
- Separate Histories: The gh-pages branch maintained a different commit history from the main branch. This meant that while the main branch might have dozens of commits with source files, the gh-pages branch only contained the output files necessary for publishing.
- Customization: Since gh-pages was solely for deployment, it was not uncommon for developers to have a minimal commit log and structure on this branch, focusing entirely on serving a clean, production-ready website.
This approach was practical and well-suited for many projects, but it also introduced an extra layer of management—maintaining two separate branches with different purposes.

As GitHub Pages matured, the platform evolved to simplify the process of deploying static websites. The changes include:
- Main Branch Publishing: GitHub updated its settings to allow publishing directly from the main branch (or master branch) without the need for a separate gh-pages branch. This means you can now designate either the root directory or a subfolder (commonly
docs/) as the source for your GitHub Pages site. - Using the docs/ Folder: The introduction of the
docs/folder option offers a simple method to separate website content from source code while staying within a single branch. This approach eliminates the need to maintain a parallel history for published content. - Streamlined CI/CD Integration: Modern CI/CD workflows benefit from having a single branch for both code and deployment. By keeping the static site source and its published version in a unified repository (using the docs/ folder), developers can reduce complexity and potential merge conflicts between deployment and development histories.
These changes were driven by feedback from the community, a desire to lower the barrier for new users, and the need for a more integrated development-deployment workflow.

- Dual-Branch Complexity: Managing two branches (main and gh-pages) could become cumbersome, especially in larger projects. Developers needed to ensure that the gh-pages branch was always in sync with the latest build of the site.
- Automated Workflows: With improved CI/CD tools, it became feasible to automate site builds and deployments directly from the main branch. This automation reduces manual errors and streamlines the development process.
- Docs/ Folder Advantage: The ability to use a subdirectory (like
docs/) allows developers to maintain a clear separation between the project’s code and its static website content while still keeping everything in one branch. This makes version control simpler and reduces the overhead associated with branching strategies. - Integrated Repository: Keeping everything within a single branch can make repository management easier, as contributors only need to work in one place without worrying about syncing multiple branches.
- Developer Feedback: Numerous discussions on GitHub Community Forums and issue trackers highlighted that many developers found the dual-branch approach unnecessarily complex. The community favored a method that minimized context switching and branch management.
- Documentation and Best Practices: GitHub’s evolving documentation began to emphasize the use of the main branch (with the docs/ folder) as a best practice. This change was influenced by both internal observations at GitHub and external feedback from the developer community.
- Streamlining Deployment: With modern development practices, continuous deployment became a central focus. A single-branch model aligns well with tools that monitor changes and trigger automated builds, leading to faster and more reliable deployments.

Today, while the gh-pages branch is still fully supported, the prevailing recommendations are:
- Publishing from the Main Branch: For many projects, it is now easier and more maintainable to publish directly from the main branch.
- Using the docs/ Folder: This option provides a convenient way to separate website content from the core project code while maintaining a single branch. It simplifies the repository’s structure and minimizes the risks of merge conflicts or deployment oversights.
- Adopting CI/CD Pipelines: Modern workflows integrate build and deployment processes within the same branch, ensuring that the published site is always up-to-date with the latest changes.
These practices are now recommended because they reduce complexity, improve developer productivity, and leverage modern continuous deployment strategies.

The gh-pages branch played a crucial role in the early days of GitHub Pages by offering a dedicated deployment mechanism that separated source code from published content. Over time, however, the need for a simpler, more integrated approach led GitHub to support direct publishing from the main branch—often using a designated subdirectory like docs/. This evolution was driven by community feedback, the rise of automated deployment workflows, and a general push toward reducing repository management complexity.
Today, while using a gh-pages branch remains an option, the consolidated approach of publishing from the main branch is considered more efficient and easier to maintain. This change reflects both the advances in tooling and the collective experience of the developer community.
