Massively is a Jekyll blog theme that reproduces the text-heavy, article-oriented HTML5UP design around a full-width background image, and it ships with Slapform email integration and an auto-generating sitemap.
What is Jekyll Massively?
Jekyll Massively (often called simply “Massively”) is a Jekyll port of the HTML5UP template of the same name, originally designed by AJ (ajlkn) and integrated with Jekyll by JekyllUp: Jekyll Themes. It is an article-oriented, text-heavy design built around a huge background image with a parallax implementation and scroll effects powered by Scrollex. As a Jekyll theme, it takes your posts and pages as input and outputs a static, blog-ready website. Setup is done by downloading the zip archive or cloning the repository, running bundle install, and launching a local server with bundle exec jekyll serve.

Who is it for?
Jekyll Massively is aimed at writers, bloggers, and editors who want a layout that emphasizes text and long-form articles rather than a typical landing page. Journalists can publish news or opinion pieces with minimal visual clutter. Personal bloggers can build an editorial-style site with a strong hero image and clean article pages. Photographers or creatives who want a full-width showcase image with text content can also use the parallax background to present portfolios.
What can you do with Jekyll Massively?
- Bloggers: create a self-hosted blog on GitHub Pages or any Jekyll-compatible host, with a built-in contact form that forwards submissions to your email.
- Writers/Journalists: publish long-form articles and use the automated sitemap to help search engines index each page with custom priority and change frequency.
- Freelancers/Professionals: present a text-focused personal site with a full-screen background image, and easily extend the contact form with Slapform webhooks for automation.
How does Jekyll Massively work?
You start by downloading the zip archive or cloning the repository, then run bundle install to fetch Ruby dependencies. After that, running bundle exec jekyll serve launches the site locally at http://127.0.0.1:4000/. To activate the contact form, put your email in _config.yml; to control the sitemap, set the sitemap front matter fields on any page.
Pros and cons
- Pros: free for personal and commercial use; includes Slapform email integration and an auto-generating sitemap; setup is a simple three-command workflow.
- Cons: demo images are not included in the repository; installation uses the multi-folder port style rather than a gem-based theme, so you'll need to copy or clone the full source.
