What Cecil is
Cecil is a free command-line PHP application for building static websites from Markdown content, media, and Twig templates. Content is kept in flat files with front matter, and themes can shape the site's design. Cecil can generate pagination, sitemaps, redirects, robots.txt, taxonomies, and RSS, along with Open Graph tags, Twitter cards, and structured data. It can create responsive WebP and AVIF images and compress them. Multilingual content and translated templates are supported, as is a local preview server. The generated site is static HTML; the maker says site visits do not require a database or server-side script execution. Installation is documented for macOS, Windows, and Linux, and PHP 8.2 or later is required. Deployment recipes cover services including Netlify, Vercel, GitHub Pages, GitLab Pages, and Surge. Starter kits include a publishing blog, a Linktree alternative, a self-hosted photo stream, and a documentation site. Cecil is distributed under the EUPL-1.2 license.

Getting started
- Choose the installation route documented for your platform: Homebrew on macOS, Scoop on Windows, or a PHAR download for Linux.
- Install PHP 8.2 or later.
- Install Cecil through the documented route, which also includes PHIVE and a manual Linux command.
- Start from a provided kit for a blog, Linktree alternative, photo stream, or documentation site, if one fits.
- Build and preview the site with Cecil's local preview server.
- Use a documented deployment recipe for a supported hosting platform.
Cecil is a PHP command-line tool for turning Markdown, media and Twig templates into static websites. It is best suited to creators who want design flexibility and a performance-focused published site, and are comfortable building from files.
Overview
Cecil keeps content in Markdown files with front matter and uses Twig templates and themes to shape the site. That separation lets authors work with portable text files while developers customize presentation. It is a file-based workflow, not a hosted visual editor, so it is a poor fit for teams that want to create and publish pages entirely through a graphical interface.
Generated pages are static: Cecil says the published site needs no database or server-side script execution for visits. That reduces the operational components of the finished site and avoids vulnerabilities associated with dynamic PHP running on the server. Cecil also generates pagination, sitemaps, redirects, robots.txt, taxonomies and RSS, covering common publishing needs without requiring those outputs to be assembled one by one.
Key features
Incremental builds and a local preview server support a quicker edit-and-check cycle. Multilingual content localization and template translation make Cecil a plausible choice for sites serving more than one language. Its image processing can generate responsive WebP and AVIF versions and compress them, while SEO helpers produce Open Graph tags, Twitter cards and structured data.
Starter kits for a blog, a Linktree alternative, a self-hosted photo stream and a documentation site provide starting structures for different projects. They do not change the underlying file-based, command-line workflow. Cecil is free software under the EUPL-1.2 license.
Pricing
Cecil's Free software plan costs nothing. It includes the software under the EUPL-1.2 license, with no usage limits stated. There is no free trial because the product is free; PHP 8.2 or later is required to run it.
Platforms
Cecil documents installation on macOS with Homebrew, Windows with Scoop and Linux with a downloaded PHAR file; PHIVE and manual installation are also supported. The generated site can be deployed using documented recipes for Netlify, Vercel, statichost, GitHub Pages, GitLab CI and Surge. Cloudflare Pages and Render no longer support PHP, so they are not suitable targets for Cecil's documented deployment workflow.
Who it's for
Cecil fits creators and developers who value a performance-oriented static site, want control over themes and templates, and are happy to manage content as files and run a PHP command-line build. Its multilingual support and publishing outputs suit blogs and documentation sites as well as smaller web projects. It is less suitable for people who need a hosted editor or want to deploy to Cloudflare Pages or Render.
Pros and cons
- Pro: Markdown content and Twig themes separate writing from presentation while allowing design customization.
- Pro: Responsive WebP and AVIF generation, compression and SEO helpers automate useful publishing work.
- Pro: Static output needs no database or server-side execution for site visits.
- Con: Building requires command-line use and PHP 8.2 or later, adding setup work for people outside that environment.
- Con: Cloudflare Pages and Render are not supported targets because they no longer support PHP.
Alternatives
Consider Hugo if you want a free, open-source static-site generator that supports Windows, macOS and Linux. Gatsby is another free option, with a free plan capped at 300 credits per month. Choose Eleventy for a free, MIT-licensed, self-hosted generator, or Nanoc for a free project described as a passion project. Zola may suit you if a free single executable is a priority. Metalsmith is a free, MIT/(L)GPL-licensed option, while Lume is a free static-site generator for Deno. Bridgetown is another free alternative.
Verdict
Choose Cecil if you want a customizable, multilingual static site built from Markdown and Twig, with image optimization and common publishing outputs included at no software cost. Its main appeal is combining a flexible authoring structure with static output; look elsewhere if command-line PHP builds or its deployment-platform constraints do not fit your workflow.
Verdict
Cecil offers a file-based approach to static site generation, with localization, image processing, and generated site metadata. Check the PHP requirement and deployment platform compatibility before choosing it.
