CAX SSG — Static Site Generator in C — C for Speed. Built by AXCORA.

As documented on ca.axcora.com / cax.axcora.com and github.com/mesinkasir/cax.

High-performance, zero-dependency static site generator written in pure C. Inspired by Eleventy and Jekyll DX, but engineered for raw C speed. No Node.js, Ruby, Python. Single binary.

Why CAX as stated on cax.axcora.com:

The web became a factory fire — 300MB node_modules to render a paragraph. CAX returns to first principles: single binary, sub-second builds, output so clean you can read it like a blueprint. Forged for writers, engineers, ateliers who value longevity over trends. Markdown in, timeless HTML out. No runtime. No tracking.

Tech Core from GitHub:

• Pure C99: No Node.js, Ruby, Python. Single binary 200KB-1.2MB
• Zero Dependencies: GCC + Make only, <500KB binary
• Blazing Fast: Build 100 pages <50ms, <5MB RAM — 1000 pages 420ms on M1 as stated on site, incremental <30ms
• Markdown + Frontmatter: YAML frontmatter support
• Zero JS Runtime: Pure HTML/CSS, optional progressive islands

Features — Eleventy-style but C speed:

• Pagination Controllers: Any content/*.md with collection: + pagination: becomes list page
• Dynamic Collections: Every folder in content/ is a collection
• Multi Layout Support: posts-list.cax, services-list.cax, portfolio-grid.cax fully dynamic
• Advanced Template Engine: {{ variables }}, {% for %}, {% if %}, {% include %}
• Pagination Object: pagination.items, pagination.prev_url, pagination.next_url, pagination.current_page, pagination.total_pages, pagination.total_items

SEO & Production Ready — auto-generated in site/ on every build:

• Tags & Taxonomies — automatic /tags/{tag}/ pages
• Sitemap — full sitemap.xml including pagination
• Feeds — feed.xml, rss.xml, feed.json JSON Feed 1.1
• Robots — auto robots.txt with sitemap reference
• Built-in Server — cax start serves site/ at http://localhost:8080

Project structure from repo:

• content/index.md → /index.html
• content/posts.md controller — collection: posts + pagination: 6 → /posts/, /posts/page/2/
• templates/layouts/default.cax, home.cax, posts-list.cax
• _data/metadata.json — site.title, site.url
• public/ — css, img copied
• site/ — generated output
