MultiTerm Astro

MultiTerm is an Astro blog theme for coders that lets you theme an entire website with Shiki color schemes and renders prose with a raw-markdown aesthetic.

What is MultiTerm?

MultiTerm is an open-source Astro blog theme created by Stel Clementine, distributed under the MIT License and currently at version 2.0.0. It takes Markdown and MDX content from the src/content directory and turns it into a static site (or dynamically rendered one), with the design built around letting you pick your favorite editor color scheme. The theme notably supports up to 59 Shiki themes, either as a single theme, a light/dark pair, or a multi-theme mode where readers choose from a dialog.

Key Features

• Theme selection — Choose from all 59 Shiki themes bundled with Expressive Code, set them in the config, and switch between them interactively via CSS variables.
• Dark/Light/Auto mode — Pick two Shiki themes and let the site automatically adapt to reader preferences, with a manual toggle button in the site header.
• Multi-theme mode — Offer three or all 59 themes and let each visitor pick their favorite from a dialog opened from the header button.
• GitHub comment section — Reader comments, discussions, and reactions are powered by Giscus, which stores comments in GitHub Discussions and is themed to match your site.
• GitHub activity widget — An optional statically generated contribution calendar appears on the homepage and follows the active color scheme.
• Markdown extensions — Admonitions, auto-generated sticky table of contents, emoji shortcodes, KaTeX math, MDX support, and reading-time estimates are built in.
• RSS and sitemap — Both are generated automatically with no extra configuration.
• SEO and social cards — The theme includes SEO best practices and auto-generates OpenGraph social card images for every page using Satori.

Who is it for?

• Developers starting a personal blog who want the look of their own editor (VSCode, etc.) and prefer a markdown-first writing flow.
• Technical writers and open-source maintainers who need a blog with GitHub-native comments, a contribution calendar, and RSS feeds for changelogs or docs.
• Astro users who want a Tailwind v4-styled starter with MDX, KaTeX math, and static-first rendering without building the design system themselves.

What can you do with MultiTerm?

• Indie developers: clone the repo, add Markdown posts under src/content, and set site-wide options in src/site.config.ts to launch a personal blog.
• Open-source projects: embed the GitHub activity widget on the homepage and enable Giscus so contributors can start discussions directly on posts.
• Design-conscious writers: let your readers switch among all 59 Shiki color schemes from a header dialog, matching their own preferences.

How does MultiTerm work?

You start by cloning the repository with git clone --depth 1 https://github.com/stelcodes/multiterm-astro my-new-blog, then install dependencies with npm install. During development you run npm run dev; for production you run npm run build && npm run preview. All configuration is centralized in src/site.config.ts, and blog content is added to the src/content directory.

Pricing

MultiTerm is free and open source under the MIT License. The author accepts optional sponsorship donations through a Ko-fi page to support continued development.

Alternatives

Two themes cited as inspiration are hugo-theme-terminal for Hugo sites and astro-theme-cactus, another Astro blog theme that pairs well with a minimal setup.
