Migrating a Jekyll-based site from GitHub Pages

Last updated Apr 21, 2026 In this tutorial, you will learn how to migrate an existing GitHub Pages site using Jekyll ↗︎ to Cloudflare Pages. Jekyll is one of the most popular static site generators used with GitHub Pages, and migrating your GitHub Pages site to Cloudflare Pages will take a few short steps.

This tutorial will guide you through:

  1. Adding the necessary dependencies used by GitHub Pages to your project configuration.
  2. Creating a new Cloudflare Pages site, connected to your existing GitHub repository.
  3. Building and deploying your site on Cloudflare Pages.
  4. (Optional) Migrating your custom domain.

Including build times, this tutorial should take you less than 15 minutes to complete.

Note

If you have a Jekyll-based site not deployed on GitHub Pages, refer to the Jekyll framework guide.

Before you begin

This tutorial assumes:

  1. You have an existing GitHub Pages site using Jekyll ↗︎
  2. You have some familiarity with running Ruby's command-line tools, and have both gem and bundle installed.
  3. You know how to use a few basic Git operations, including add, commit, push, and pull.
  4. You have read the Get Started guide for Cloudflare Pages.

If you do not have Rubygems (gem) or Bundler (bundle) installed on your machine, refer to the installation guides for Rubygems ↗︎ and Bundler ↗︎.

Preparing your GitHub Pages repository

Note

If your GitHub Pages repository already has a Gemfile and Gemfile.lock present, you can skip this step entirely. The GitHub Pages environment assumes a default set of Jekyll plugins that are not explicitly specified in a Gemfile.

Your existing Jekyll-based repository must specify a Gemfile (Ruby's dependency configuration file) to allow Cloudflare Pages to fetch and install those dependencies during the build step.

Specifically, you will need to create a Gemfile and install the github-pages gem, which includes all of the dependencies that the GitHub Pages environment assumes.

Version 2 of the Pages build environment will use Ruby 3.2.2 for the default Jekyll build. Please make sure your local development environment is compatible.

Set Ruby Versionsh

brew install ruby@3.2
export PATH="/usr/local/opt/ruby@3.2/bin:$PATH"

Create a Gemfilesh

cd my-github-pages-repo
bundle init

Open the Gemfile that was created for you, and add the following line to the bottom of the file:

Specifying the github-pages versionruby

gem "github-pages", group: :jekyll_plugins

Your Gemfile should resemble the below:

# frozen_string_literal: true

source "https://rubygems.org"

git_source(:github) { |repo_name| "https://github.com/#{repo_name}" }

# gem "rails"
gem "github-pages", group: :jekyll_plugins

Run bundle update, which will install the github-pages gem for you, and create a Gemfile.lock file with the resolved dependency versions.

Running bundle updatesh

bundle update
# Bundler will show a lot of output as it fetches the dependencies

This should complete successfully. If not, verify that you have copied the github-pages line above exactly, and have not commented it out with a leading #.

You will now need to commit these files to your repository so that Cloudflare Pages can reference them in the following steps:

Commit Gemfile and Gemfile.locksh

git add Gemfile Gemfile.lock
git commit -m "deps: added Gemfiles"
git push origin main

Configuring your Pages project

With your GitHub Pages project now explicitly specifying its dependencies, you can start configuring Cloudflare Pages. The process is almost identical to deploying a Jekyll site.

Note

If you are configuring your Cloudflare Pages site for the first time, refer to the Git integration guide, which explains how to connect your existing Git repository to Cloudflare Pages.

To deploy your site to Pages:

  1. In the Cloudflare dashboard, go to the Workers & Pages page. Go to Workers & Pages ↗
  2. Select Create application > Pages > Import an existing Git repository.
  3. Select the new GitHub repository that you created and, in the Set up builds and deployments section, provide the following information:
Configuration option Value
Production branch main
Build command jekyll build
Build directory _site

After you have configured your site, you can begin your first deploy. You should see Cloudflare Pages installing jekyll, your project dependencies, and building your site, before deploying it.

Note

For the complete guide to deploying your first site to Cloudflare Pages, refer to the Get started guide.

After deploying your site, you will receive a unique subdomain for your project on *.pages.dev. Every time you commit new code to your Jekyll site, Cloudflare Pages will automatically rebuild your project and deploy it. You will also get access to preview deployments on new pull requests, so you can preview how changes look to your site before deploying them to production.

Migrating your custom domain

If you are using a custom domain with GitHub Pages ↗︎, you must update your DNS record(s) to point at your new Cloudflare Pages deployment. This will require you to update the CNAME record at the DNS provider for your domain to point to <your-pages-site>.pages.dev, replacing <your-username>.github.io.

Note that it may take some time for DNS caches to expire and for this change to be reflected, depending on the DNS TTL (time-to-live) value you set when you originally created the record.

Refer to the adding a custom domain section of the Get started guide for a list of detailed steps.
