Cecil

Cecil is a command-line PHP application for building static websites from Markdown pages, media, and Twig templates. Content stays in Markdown files with front matter, while Twig themes give creators options for shaping a site's design. Cecil generates common site elements such as pagination, sitemaps, redirects, robots.txt, taxonomies, and RSS feeds. It can also create responsive WebP and AVIF images and compress them. Multilingual content and translated templates are supported, and a local preview server is available. SEO helpers generate Open Graph tags, Twitter cards, and structured data. The output is static HTML, which Cecil says visitors can access without a database or server-side script execution. Installation is documented for Linux, macOS, and Windows, and PHP 8.2 or later is required. Deployment recipes include Netlify, Vercel, GitHub Pages, and GitLab Pages. Cecil is free software under the EUPL-1.2 license.

Cecil combines static site generation with image optimization, localization, and built-in site metadata generation. Its PHP requirement and the stated platform limitation are worth checking against your deployment plans.

Cecil suits creators who want to build a website from Markdown and prioritize performance while retaining design flexibility. Its localization, themes, and starter kits may also fit publishers and documentation authors.

Cecil suits creators and developers who want to build a customizable site from files and prioritize performance. It produces static websites from Markdown and Twig, but its command-line workflow and PHP requirement make it a poor fit for anyone seeking a hosted visual editor.

Overview

Cecil combines Markdown pages with front matter, media, and Twig templates to build static sites. Content stays in flat files rather than a database, and themes provide room to shape the design. The trade-off is a file-based build process: Cecil is for people willing to work with a command line, not those who want to edit and publish entirely through a hosted interface.

Generated pages have no database or server-side script execution during visits. That removes server-side components from the published site and avoids vulnerabilities tied to dynamic PHP there, though PHP is still required to build with Cecil. Incremental builds and a local preview server support an iterative workflow.

Key features

Cecil generates pagination, sitemaps, redirects, robots.txt, taxonomies, and RSS, covering common publishing needs without requiring users to create each output by hand. Its SEO helpers can produce Open Graph tags, Twitter cards, and structured data. For image-heavy sites, responsive WebP and AVIF generation and compression can reduce image load, a useful advantage for creators making performance a priority.

Multilingual content and template translation make Cecil a plausible choice for localized sites. Starter kits for a publishing blog, a Linktree alternative, a self-hosted photo stream, and documentation sites offer starting points, while Twig and theme support leave room to customize presentation. These capabilities suit a range of site types, but they remain part of a generator workflow rather than a managed publishing service.

Pricing

Cecil is free software under the EUPL-1.2 license. Its Free software plan costs nothing. The plan has no stated usage limits; there is no free trial because the software is free. This makes it accessible for both personal projects and broader use, with no paid tier described to unlock additional capacity.

Platforms

Cecil supports Linux, macOS, and Windows installations, with PHP 8.2 or later required. The maker documents installation through Homebrew on macOS, Scoop on Windows, and a PHAR download, as well as other installation methods. Deployment recipes cover Netlify, Vercel, statichost, GitHub Pages, GitLab CI, and Surge. Cloudflare Pages and Render no longer support PHP, so users targeting either platform should choose another deployment path or a different generator.

Who it's for

Cecil is best for creators who are comfortable with files and command-line builds and want control over site design alongside a performance-focused static output. Its image processing and built-in publishing outputs are particularly relevant to image-rich or multilingual sites. It is not the right choice for users who need a point-and-click hosted editor or whose deployment plan depends on Cloudflare Pages or Render.

Pros and cons

• Pros: Static output avoids a database and server-side execution for visitors, reducing the components involved in hosting.
• Pros: Responsive WebP and AVIF generation, compression, and SEO metadata helpers cover useful performance and publishing tasks.
• Pros: Twig, themes, localization, and starter kits offer flexibility across several site types.
• Cons: Building requires PHP 8.2 or later and a command-line workflow, which rules out users seeking a hosted visual editor.
• Cons: Cloudflare Pages and Render are not supported deployment targets because they no longer support PHP.

Alternatives

Explore the Static site generators category if you want to compare more tools. Choose Gatsby if its API, self-hosted, and web platform options suit your project; its open-source framework and Free plan are both priced as free, though the latter has a 300-credit monthly limit. Eleventy is another free, self-hosted static-site generator, with Linux, macOS, and Windows support and an MIT license.

Nanoc is a free passion project for readers considering another Linux, macOS, or Windows option. Pick Bridgetown if its API, self-hosted, Linux, or Windows platform support is a better fit. Zola is free, runs on Linux, macOS, and Windows, and comes as a single executable, which may appeal to those who prefer that packaging.

Hugo is an open-source alternative that is free to use across Windows, macOS, and Linux. Lume is a Deno static-site generator for readers looking at a web or self-hosted option. Metalsmith is free, MIT/(L)GPL-licensed software with API, Linux, macOS, and Windows platform support.

Verdict

Choose Cecil if you want a free, flexible static-site generator that combines Markdown and Twig with image optimization, localization, and publishing outputs. Its strongest case is performance-minded creators who can work with a command line and meet the PHP 8.2 requirement. Look elsewhere if you need hosted visual editing or must deploy to Cloudflare Pages or Render.
