Template Details
koibumi-blog is a static blog template built with Astro and paired with the koibumi design system. The repository is released under the MIT license, and you can create your own blog repository directly via GitHub's Use this template button.
For content, the template supports writing in Markdown and MDX, includes a built-in tag system for categorizing posts, and integrates KaTeX math formulas and Expressive Code syntax highlighting. Site configuration is centralized in content/site.json, where you can set the title, description, favicon, intro, and copyright attribution; the site URL is configured in astro.config.mjs.
The interface uses a card-based layout and comic-style fonts (Comic Neue for English, Klee One for Japanese), provides dark mode and theme switching, and includes a mobile-first responsive grid. The template comes with an automatically generated sitemap and RSS feed, uses Svelte sparingly for interactive components, organizes styles modularly with SCSS, and uses TypeScript throughout.
Usage limitations: the package manager requires pnpm; third-party assets such as demo images, fonts, and icons must be checked separately under their respective licenses, and the code's MIT license does not cover these assets; external services such as domains and hosting may incur costs. Metrics such as Lighthouse scores and bundle sizes mentioned in the README are the author's own claims and have not been independently verified in this material.

Our heuristic uses license records (up to 30), a demo link (12), a preview (10), stars (15), recorded maintenance (15), description completeness (8), feature records (5) and classification data (5). It is not a code, security or performance test, or a Google score. A link does not establish tested functionality.
