Nanoc

Nanoc is a Ruby-based static-site generator for developers who want direct control over content processing, templates, and deployment. It suits projects whose content lives in files and whose structure needs to vary by page type, from a personal blog to a corporate site. The trade-off is a command-line, developer-oriented workflow and a Ruby requirement that narrows its audience.

Overview

Nanoc converts source material such as Markdown or AsciiDoc into static HTML. Sites are built locally from the command line, then the generated files are deployed when ready. This separation keeps the published site free of dynamic content, which the project says avoids most common attacks, but it also means editorial work is not handled through a built-in content-management interface.

Content is normally managed on the filesystem rather than in a CMS. Nanoc can still bring in information from databases and web APIs when a project needs external data. Free-form metadata lets builders classify and process pages as articles, chapters, reviews, recipes, or other types instead of forcing every page into one fixed model.

Nanoc has been developed since 2007 by its Berlin-based maker and is released under the MIT license. The project provides a GitHub repository, issue tracker, GitHub discussions, and a Google group for support. Nanoc 4.14.8 was released on August 30, 2026.

Key features

Markup and templates

Authors can choose Markdown, AsciiDoc, or Textile for source content, then use eRuby, Haml, or Mustache to construct pages. That breadth is useful when a team has an established markup or templating preference. It also puts more architectural decisions in the developer's hands than a narrowly opinionated generator would.

Processing and data

Custom filters and helpers extend both transformation and template behavior, making Nanoc suitable for bespoke publishing rules. Database and web-API access allows generated pages to incorporate external information, although the resulting workflow remains a build process rather than live CMS editing.

Build and deployment

Incremental builds avoid regenerating unchanged material, an important advantage as a site grows. A local preview server supports iterative development, while multilingual support helps projects publishing in more than one language. Nanoc includes a nanoc deploy command and integrates with multiple deployment mechanisms, with examples covering Git, rsync, GitHub Pages, Bitbucket, GitLab Pages, and Netlify. Pre-deployment checks provide a useful gate before generated files are published.

Pricing

Nanoc has one free plan and no paid tiers, seat charges, quotas, trial period, or renewal terms to weigh. It is therefore a practical choice for individuals and teams that can provide their own development and hosting setup. The absence of a CMS or managed service is the corresponding cost: organizations wanting nontechnical publishing or vendor-operated infrastructure should look elsewhere.

Platforms

Nanoc runs on Linux, macOS, and Windows, but official support is limited to macOS and Linux. Windows has known limitations, so Windows-based teams should treat compatibility as a project risk rather than an equal-platform promise.

Installation uses RubyGems with gem install nanoc. Nanoc requires Ruby 3.1 or newer and guarantees support on the CRuby implementation, making the runtime choice part of deployment planning.

Who it's for

Nanoc is aimed at developers comfortable with Ruby, command-line tools, filesystem-managed content, and assembling their own publishing pipeline. Its metadata model and extensibility are particularly valuable for sites with several content types or custom transformations. Incremental builds, previews, multilingual output, and deployment checks also support larger or more structured projects.

It is a poor fit for teams that need a graphical CMS, collaborative in-browser editing, or officially supported Windows development. Nontechnical authors may find the file-and-build workflow burdensome even though the generated result is lightweight and static.

Pros and cons

Pros

• Flexible content model: Free-form metadata can represent many page types without a fixed CMS schema.
• Broad authoring choices: Markdown, AsciiDoc, Textile, eRuby, Haml, and Mustache accommodate varied toolchains.
• Extensible builds: Custom filters and helpers allow project-specific processing.
• Scalable generation workflow: Incremental builds and a local preview server help as sites become larger.
• Deployment coverage: The deploy command, provider examples, and pre-deployment checks reduce repetitive release work.
• No license cost: The MIT-licensed project is free to use.

Cons

• No CMS: Filesystem-based authoring leaves editorial structure and collaboration to the team.
• Ruby dependency: Ruby 3.1+ and guaranteed CRuby support add runtime requirements.
• Windows limitations: Official support does not extend to Windows, despite the platform being listed.
• Developer-first operation: Command-line development and generated-file deployment are unsuitable for users seeking a managed interface.

Alternatives

Browse Static site generators for a wider field. Choose Hugo instead if you want a free, open-source generator with Windows, macOS, and Linux support. Gatsby is the better alternative when an API, self-hosted, or web platform and a free tier with a 300-credit monthly limit fit your delivery model.

Cecil offers free software for Linux, macOS, and Windows with no stated usage limits. Pick Publii if a free, open-source desktop CMS is preferable. Eleventy is another free MIT-licensed, self-hosted option across the major desktop platforms, while Nikola suits users who prefer a Python 3.8+ open-source generator. Zola provides a free single-executable approach, and Jekyll is a free static-site generator with no stated pricing or usage limits.

Verdict

Choose Nanoc if you are a Ruby developer who wants a free, extensible build system, varied markup and templates, and precise control over content types and deployment. Its strongest reason to exist is that it lets a project define its own publishing rules without CMS constraints. Look elsewhere if you need an editor-friendly CMS, a managed workflow, or dependable official Windows support.
