## Overview

Use Astro when the site has interactive components, MDX, or a designer who wants Tailwind and React parts. Use Hugo when the brief is a blog or docs site that has to build 10,000 pages in under a minute and ship zero JavaScript. The split has hardened since Astro 5: Astro owns "content sites that need islands"; Hugo owns "pure content sites at scale." See [[frontend/astro]] for the Astro rule set.

## When Astro wins

Astro is the right pick when the site mixes prose with interactive components, or when the team already lives in the JavaScript ecosystem.

- Component model: import React, Vue, Svelte, or Solid components into `.astro` files and the build ships only the ones marked `client:*`. Hugo has no equivalent.
- Content Collections give typed frontmatter with Zod schemas; you catch a missing `date` field at build time, not at deploy.
- MDX is first-class. Embed a Recharts chart inside a blog post without a plugin shim.
- Tailwind, Partytown, View Transitions, and image optimization are official integrations; Hugo asks you to wire each one yourself.
- The hiring pool is the same as Next.js and React; onboarding a frontend engineer takes a day.

## When Hugo wins

Hugo is the right pick when the site is pure content, the page count is large, or the team prefers Go templating over JSX.

- Build speed: Hugo compiles 10,000 markdown pages in seconds. Astro on the same content is 5 to 20 times slower because each page runs the component pipeline.
- Output: Hugo ships HTML plus your own CSS; no framework runtime, no hydration script, no client-side router unless you add one.
- Templating: Go templates plus partials and shortcodes cover most blog and docs needs without a JavaScript dependency tree.
- Single binary deploy: `hugo` is one Go binary; no `node_modules`, no lockfile drift, no `npm ci` in CI.
- Long-lived projects: a Hugo site from 2019 still builds on a fresh machine. Astro projects from two years ago often need framework upgrades to build.

## Trade-offs at a glance

| Dimension          | Astro                              | Hugo                                  |
| ------------------ | ---------------------------------- | ------------------------------------- |
| Templating         | `.astro` files plus JSX components | Go templates and shortcodes           |
| Interactivity      | Islands via `client:*`             | None native; add JS manually          |
| Build speed (10k)  | Minutes                            | Seconds                               |
| Output size        | HTML plus optional JS              | HTML only                             |
| Content schemas    | Zod-typed Content Collections      | Untyped frontmatter                   |
| MDX                | First-class                        | Not supported                         |
| Image optimization | Built-in `<Image>`                 | `image` shortcodes; less ergonomic    |
| Plugins            | npm integrations                   | Built-in features; harder to extend   |
| Hosting            | Vercel, Cloudflare, static host    | Any static host; trivial Pages deploy |
| Hiring             | JS frontend pool                   | Smaller; Go familiarity helps         |

## Migration cost

Hugo-to-Astro is the common direction; Astro-to-Hugo is rare and painful.

- Hugo to Astro: rewrite layouts as `.astro` files, port shortcodes to components, and convert Go template ranges to `.map()` calls. Content frontmatter usually survives untouched. Plan one engineer-week per 50 templates plus a day for the content schema.
- Astro to Hugo: only worth it if the site outgrew Astro's build time. Rewrite components as Go partials, lose the type checking, and accept that interactive sections will need a separate bundler. Plan two to four engineer-weeks for a docs-sized site.
- Cheaper path for both: stay on the current tool, fix the actual bottleneck (Astro build caching, Hugo asset pipeline), and revisit only if the build crosses a real CI budget.

## Recommendation

- New marketing site or product blog under 500 pages: Astro. See [[frontend/astro]] and [[comparisons/nextjs-vs-astro]].
- Docs site for a library or company handbook with 1,000-plus pages: Hugo unless you need MDX.
- This site (Quartz, also a Markdown SSG): the same logic applies; see [[tooling/quartz]].
- Designer-driven brand site with bespoke interactions: Astro with Tailwind and shadcn islands.
- Government, archival, or compliance site that must build the same in five years: Hugo. One binary, no churn.
- Already on Cloudflare Pages: either works; see [[comparisons/vercel-vs-cloudflare]] for the host trade-off.
