Hugo's build process is roughly divided into three steps: 1. Process content (walk file system and insert source nodes into content tree) 2. Assemble content (assemble pages and resources according to sites matrix) 3. Render content In #13679 we consolidated the page creation logic into one place (the assemble step). This made it much simpler to reason about, but it lost us some performance esp. in big content trees. This commit re-introduces parallelization in the first step in the assemble step by handling each top level section in its own goroutine. This gives significant performance improvements for content trees with many sections.

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:
- Image processing – Convert, resize, crop, rotate, adjust colors, apply filters, overlay text and images, and extract EXIF data
- JavaScript bundling – Transpile TypeScript and JSX to JavaScript, bundle, tree shake, minify, create source maps, and perform SRI hashing.
- Sass processing – Transpile Sass to CSS, bundle, tree shake, minify, create source maps, perform SRI hashing, and integrate with PostCSS
- Tailwind CSS processing – Compile Tailwind CSS utility classes into standard CSS, bundle, tree shake, optimize, minify, perform SRI hashing, and integrate with PostCSS
And with Hugo Modules, you can share content, assets, data, translations, themes, templates, and configuration with other projects via public or private Git repositories.
See the features section of the documentation for a comprehensive summary of Hugo's capabilities.

Editions
Hugo is available in three editions: standard, extended, and extended/deploy. While the standard edition provides core functionality, the extended and extended/deploy editions offer advanced features.
| Feature | extended edition | extended/deploy edition |
|---|---|---|
| Encode to the WebP format when processing images. You can decode WebP images with any edition. | ✔️ | ✔️ |
| Transpile Sass to CSS using the embedded LibSass transpiler. You can use the Dart Sass transpiler with any edition. | ✔️ | ✔️ |
| Deploy your site directly to a Google Cloud Storage bucket, an AWS S3 bucket, or an Azure Storage container. See details. | ❌ | ✔️ |
Unless your specific deployment needs require the extended/deploy edition, we recommend the extended edition.
