Static Site Generators: Why We Build with Hugo

A static site generator (SSG) takes your content, applies templates, and produces finished HTML files at build time. No server-side rendering at request time. No database queries when a visitor arrives. Just pre-built pages served from a CDN.

There are dozens of static site generators available in 2026. We have evaluated most of them. We build with Hugo. This article explains why – not as a blanket recommendation, but as a transparent account of the technical reasoning behind a deliberate architectural choice.

For the broader context on our approach, read our complete guide to headless website development in Australia and our explanation of JAMstack architecture.

What a static site generator does

Every SSG follows the same fundamental process:

1. Content is stored as files (typically Markdown with structured front matter)
2. Templates define how that content is rendered into HTML
3. The build process combines content with templates to produce finished HTML pages
4. The output is deployed to a CDN for global delivery

The critical distinction from traditional platforms: this build process happens once, at deploy time. When a visitor requests a page, they receive the already-built file. The server does not think. It delivers.

The contenders

The modern SSG landscape has four major players, each with different philosophies and trade-offs.

Hugo

• Language: Go
• Build speed: Thousands of pages in under 1 second
• JavaScript runtime: None by default
• Output: Pure static HTML, CSS, and optional JS
• Template language: Go templates

Next.js

• Language: JavaScript/TypeScript (React)
• Build speed: Minutes for large sites
• JavaScript runtime: Required (React hydration)
• Output: HTML + JavaScript bundle
• Template language: JSX/React components

Gatsby

• Language: JavaScript/TypeScript (React)
• Build speed: Slow for large sites (GraphQL data layer overhead)
• JavaScript runtime: Required (React hydration)
• Output: HTML + JavaScript bundle
• Template language: JSX/React components

Astro

• Language: JavaScript/TypeScript (multi-framework)
• Build speed: Fast (but slower than Hugo)
• JavaScript runtime: Optional (“islands” architecture)
• Output: HTML with optional JS islands
• Template language: Astro components (supports React, Vue, Svelte)

Why we chose Hugo

Build speed is not a luxury

Hugo builds thousands of pages in under one second. A 500-page site rebuilds in approximately 300 milliseconds. This is not a benchmark curiosity – it has real workflow implications.

When a content editor saves a change in CloudCannon, a rebuild is triggered. With Hugo, that rebuild completes before the editor has switched browser tabs. With Next.js or Gatsby, the same rebuild can take 30 seconds to several minutes for large sites. Multiply this across dozens of daily edits and the productivity difference is significant.

Fast builds also mean fast deployments. Every push to Git triggers a build and deploy. With Hugo, your changes are live globally in under 60 seconds.

Zero JavaScript by default

This is the decisive factor for business websites.

Next.js and Gatsby are React-based. Even when they pre-render pages at build time (Static Site Generation mode), they ship React’s runtime to the browser and “hydrate” the page – re-attaching JavaScript event handlers to the already-rendered HTML. This hydration step requires downloading, parsing, and executing a JavaScript bundle before the page is fully interactive.

For a marketing site or a content-heavy business site, this JavaScript is unnecessary overhead. Your visitor does not need React to read a paragraph, view an image, or click a navigation link. Shipping a 100-200KB JavaScript framework for content that is fundamentally static violates the principle of delivering only what the user needs.

Hugo outputs pure HTML and CSS. If a page needs JavaScript – a form validation, a scroll animation, an interactive component – we add it surgically, for that specific functionality. The baseline is zero, and every addition is justified.

This directly impacts Core Web Vitals. Interaction to Next Paint (INP) measures how quickly the page responds to user interactions. JavaScript-heavy pages score poorly because the browser’s main thread is busy parsing and executing framework code. Hugo sites score well because there is nothing competing for the main thread. See our Core Web Vitals 2026 guide for the full breakdown.

No JavaScript ecosystem dependency

Hugo is written in Go and ships as a single binary. There is no node_modules folder. No dependency tree with hundreds of packages. No npm audit warnings. No breaking changes from upstream package updates.

JavaScript-based SSGs inherit the JavaScript ecosystem’s complexity. A Next.js project depends on React, webpack (or Turbopack), and dozens of supporting packages. Any of these can introduce breaking changes, security vulnerabilities, or compatibility issues. Maintaining a JavaScript-based SSG project over three to five years requires ongoing dependency management.

Hugo’s single binary means your build process today will work identically in three years without modification. For business websites that need long-term stability, this is a material advantage.

Go template language

Hugo uses Go’s built-in template language. It is less immediately familiar than JSX or HTML-like component syntax, but it is deliberately constrained. You cannot write arbitrary application logic in templates. This constraint is a feature: it keeps templates focused on presentation and prevents the template layer from becoming an application layer.

For developers accustomed to React’s flexibility, this feels restrictive. For business websites that need predictable, maintainable templates over years of production use, this constraint produces cleaner, more durable code.

When Hugo is not the right choice

We are honest about the boundaries.

Complex web applications

If you are building a SaaS dashboard, a real-time collaboration tool, or an application with heavy client-side state management, Hugo is not the right tool. These use cases genuinely require a JavaScript framework, and Next.js or Astro’s hybrid approach is better suited.

Teams with deep React expertise and no Go experience

If your in-house development team is React-native and you intend to maintain the site internally, the learning curve for Hugo’s Go templates may not be justified. Next.js would leverage your existing skills.

Highly dynamic content

If your site requires real-time content updates that cannot wait for a rebuild (live dashboards, real-time pricing, social feeds), a purely static approach requires supplementing with client-side data fetching. Hugo handles this, but frameworks with built-in server-side rendering (Next.js) may be more ergonomic for heavy dynamic requirements.

Hugo and CloudCannon: The editing experience

The historical criticism of static site generators is that they are developer tools with no editorial interface. This was valid in 2015. It is not valid in 2026.

CloudCannon provides visual, on-page editing for Hugo sites. Content editors click on a heading and type. They rearrange page sections by dragging. They add new blog posts through a familiar interface that feels comparable to WordPress’s block editor.

Behind the scenes, CloudCannon saves changes as Markdown files with YAML front matter, committed directly to your Git repository. The editor never touches code. The developer never has to process content requests. The separation of concerns is clean.

The performance evidence

Our Hugo-built sites consistently achieve:

• Lighthouse Performance scores: 95-100
• LCP (Largest Contentful Paint): Under 1.5 seconds, typically under 1 second
• CLS (Cumulative Layout Shift): 0 (zero layout shift by design)
• INP (Interaction to Next Paint): Under 100ms (minimal JavaScript on the main thread)
• Total page weight: Under 200KB for a typical content page

These are not optimised benchmarks. They are the natural output of an architecture that starts at zero and adds only what is needed. Template-based sites and JavaScript-framework sites start heavy and optimise downward. Hugo sites start light by default.

Build with the right tool for the job

Hugo is not the best static site generator for every project. It is the best static site generator for business websites, content platforms, and ecommerce storefronts where performance, security, and long-term maintainability are non-negotiable.
