There are some breaking changes in this commit, see #11455. Closes #11455 Closes #11549 This fixes a set of bugs (see issue list) and it is also paying some technical debt accumulated over the years. We now build with Staticcheck enabled in the CI build. The performance should be about the same as before for regular sized Hugo sites, but it should perform and scale much better to larger data sets, as objects that uses lots of memory (e.g. rendered Markdown, big JSON files read into maps with transform.Unmarshal etc.) will now get automatically garbage collected if needed. Performance on partial rebuilds when running the server in fast render mode should be the same, but the change detection should be much more accurate. A list of the notable new features: * A new dependency tracker that covers (almost) all of Hugo's API and is used to do fine grained partial rebuilds when running the server. * A new and simpler tree document store which allows fast lookups and prefix-walking in all dimensions (e.g. language) concurrently. * You can now configure an upper memory limit allowing for much larger data sets and/or running on lower specced PCs. We have lifted the "no resources in sub folders" restriction for branch bundles (e.g. sections). Memory Limit * Hugos will, by default, set aside a quarter of the total system memory, but you can set this via the OS environment variable HUGO_MEMORYLIMIT (in gigabytes). This is backed by a partitioned LRU cache used throughout Hugo. A cache that gets dynamically resized in low memory situations, allowing Go's Garbage Collector to free the memory. New Dependency Tracker: Hugo has had a rule based coarse grained approach to server rebuilds that has worked mostly pretty well, but there have been some surprises (e.g. stale content). This is now revamped with a new dependency tracker that can quickly calculate the delta given a changed resource (e.g. a content file, template, JS file etc.). This handles transitive relations, e.g. $page -> js.Build -> JS import, or $page1.Content -> render hook -> site.GetPage -> $page2.Title, or $page1.Content -> shortcode -> partial -> site.RegularPages -> $page2.Content -> shortcode ..., and should also handle changes to aggregated values (e.g. site.Lastmod) effectively. This covers all of Hugo's API with 2 known exceptions (a list that may not be fully exhaustive): Changes to files loaded with template func os.ReadFile may not be handled correctly. We recommend loading resources with resources.Get Changes to Hugo objects (e.g. Page) passed in the template context to lang.Translate may not be detected correctly. We recommend having simple i18n templates without too much data context passed in other than simple types such as strings and numbers. Note that the cachebuster configuration (when A changes then rebuild B) works well with the above, but we recommend that you revise that configuration, as it in most situations should not be needed. One example where it is still needed is with TailwindCSS and using changes to hugo_stats.json to trigger new CSS rebuilds. Document Store: Previously, a little simplified, we split the document store (where we store pages and resources) in a tree per language. This worked pretty well, but the structure made some operations harder than they needed to be. We have now restructured it into one Radix tree for all languages. Internally the language is considered to be a dimension of that tree, and the tree can be viewed in all dimensions concurrently. This makes some operations re. language simpler (e.g. finding translations is just a slice range), but the idea is that it should also be relatively inexpensive to add more dimensions if needed (e.g. role).

A fast and flexible static site generator built with love by bep, spf13, and friends in Go.
Website | Installation | Documentation | Support | Contributing | Mastodon
Overview
Hugo is a static site generator written in Go, optimized for speed and designed for flexibility. With its advanced templating system and fast asset pipelines, Hugo renders a complete site in seconds, often less.
Due to its flexible framework, multilingual support, and powerful taxonomy system, Hugo is widely used to create:
- Corporate, government, nonprofit, education, news, event, and project sites
- Documentation sites
- Image portfolios
- Landing pages
- Business, professional, and personal blogs
- Resumes and CVs
Use Hugo's embedded web server during development to instantly see changes to content, structure, behavior, and presentation. Then deploy the site to your host, or push changes to your Git provider for automated builds and deployment.
Hugo's fast asset pipelines include:
- CSS bundling – transpilation (Sass), tree shaking, minification, source maps, SRI hashing, and PostCSS integration
- JavaScript bundling – transpilation (TypeScript, JSX), tree shaking, minification, source maps, and SRI hashing
- Image processing – convert, resize, crop, rotate, adjust colors, apply filters, overlay text and images, and extract EXIF data
And with Hugo Modules, you can share content, assets, data, translations, themes, templates, and configuration with other projects via public or private Git repositories.

Installation
Install Hugo from a prebuilt binary, package manager, or package repository. Please see the installation instructions for your operating system:
Build from source
Hugo is available in two editions: standard and extended. With the extended edition you can:
- Encode to the WebP format when processing images. You can decode WebP images with either edition.
- Transpile Sass to CSS using the embedded LibSass transpiler. The extended edition is not required to use the Dart Sass transpiler.
Prerequisites to build Hugo from source:
- Standard edition: Go 1.20 or later
- Extended edition: Go 1.20 or later, and GCC
Build the standard edition:
go install github.com/gohugoio/hugo@latest
Build the extended edition:
CGO_ENABLED=1 go install -tags extended github.com/gohugoio/hugo@latest
Documentation
Hugo's documentation includes installation instructions, a quick start guide, conceptual explanations, reference information, and examples.
Please submit documentation issues and pull requests to the documentation repository.
Support
Please do not use the issue queue for questions or troubleshooting. Unless you are certain that your issue is a software defect, use the forum.
Hugo’s forum is an active community of users and developers who answer questions, share knowledge, and provide examples. A quick search of over 20,000 topics will often answer your question. Please be sure to read about requesting help before asking your first question.
Contributing
You can contribute to the Hugo project by:
- Answering questions on the forum
- Improving the documentation
- Monitoring the issue queue
- Creating or improving themes
- Squashing bugs
Please submit documentation issues and pull requests to the documentation repository.
If you have an idea for an enhancement or new feature, create a new topic on the forum in the "Feature" category. This will help you to:
- Determine if the capability already exists
- Measure interest
- Refine the concept
If there is sufficient interest, create a proposal. Do not submit a pull request until the project lead accepts the proposal.
