Gollum vs. Blume

The Gollum repository is made up of text or markup files that users can modify with ease. You have the ability to arrange your pages in directories based on your individual needs and preferences. Beyond plain text, you can also add various content types, such as images, PDFs, and even custom headers or footers for your pages. By default, Gollum employs the kramdown gem for rendering Markdown, but you can select from any Markdown renderer that supports github-markup, including CommonMark through the commonmarker gem. The first renderer you install from the available options will take priority, meaning that if both redcarpet and github/markdown are installed, only the first will be in use. To switch to a different renderer, you simply need to run a gem install command for your chosen option, which allows you to tailor your Markdown rendering experience. Consequently, Gollum serves as a highly adaptable platform for the efficient management of documentation and various types of content, catering to a wide range of user requirements. Additionally, this flexibility makes it an ideal choice for collaborative projects where documentation needs may evolve over time.

Blume is an open-source framework centered around Markdown, aimed at facilitating the creation of production-ready documentation sites with minimal setup. Each project resides in a dedicated folder filled with Markdown files, which enables the automatic generation of navigation, and features such as search, theming, and Open Graph images are readily available, alongside advanced customization options for those who desire more control. The framework includes more than 30 components and Markdown extensions that are aware of themes, allowing users to add various elements like callouts, cards, steps, tabs, file trees, package-install tabs, code groups, Mermaid diagrams, and KaTeX math without the hassle of managing imports or JSX. Furthermore, Blume provides functionality to produce interactive references for OpenAPI and AsyncAPI, showcasing endpoints, schemas, and a live “Try it” playground, while also integrating a built-in changelog that can be sourced from Markdown content or GitHub Releases. Content can be gathered from local Markdown files, remote repositories, CMS platforms, Notion, or tailored backends, which allows for a smooth integration of diverse content into one cohesive website. It is also designed to meet the needs of both human users and AI, as every page can be accessed in its raw Markdown form, indexed through llms.txt, and queried via an integrated AI assistant to enhance user interaction. In summary, Blume not only simplifies the documentation process but also enhances accessibility and efficiency, making it a valuable tool for a wide range of users. As an added benefit, the ability to easily customize and extend functionality ensures that users can tailor their documentation sites to meet specific requirements.
