CMS for a Microsite: Lightweight Content Without the Overhead

A microsite is a small, focused site — a campaign page, a product launch, an event, a standalone landing experience — usually with a short lifespan or a single job. The content need is real but small: a few pages, some copy a marketer can edit, maybe a blog or updates section. That awkward middle is where CMS choice gets tricky. WordPress is overkill and a maintenance liability for something small. Hand-coding means a developer for every copy tweak. A headless CMS hits the sweet spot: a real editor for the marketer, a lightweight footprint for the developer. This post covers how to run a microsite on a CMS without the overhead.

The microsite CMS problem

Microsites have an unusual shape:

• Small content — a handful of pages, not hundreds.
• Short or uncertain lifespan — a campaign might run for weeks; a launch site might become permanent.
• Non-technical editors — marketing needs to change copy and images without a developer.
• Fast to spin up, cheap to run — you don't want to provision heavy infrastructure for something small.
• Often many at once — agencies and marketing teams run several microsites in parallel.

WordPress carries too much weight and maintenance for this. Hand-coding blocks the marketer. The fit is something light with a real editor.

Why headless fits microsites

A headless CMS separates content from presentation, which suits microsites perfectly. Build the microsite front end however you like — a single-page app, a static site, a few Astro or Next.js pages — and pull the editable content from the CMS. The marketer edits in the admin; the developer builds a lean front end that fetches JSON.

UnfoldCMS is one option. It's a self-hosted CMS on Laravel with a REST API at /api/v1/*. For microsites, a few traits matter:

• Light and fast to run — deploy on a $5 VPS or shared hosting; no heavy stack.
• Real editor — marketers change copy and images in a modern admin without touching code.
• One-time cost — no per-site subscription, which matters when you run several microsites.
• REST + fetch — the front end pulls content with plain fetch; no SDK.

One CMS, many microsites

Here's a pattern that fits agencies and marketing teams: run one CMS instance and use it to feed multiple microsites. Categories or content types separate each microsite's content, and each front end fetches only what it needs. One admin, one server, one bill — many small sites. It's far cheaper than a WordPress install (or a SaaS subscription) per microsite.

For a static microsite, prerender the pages from CMS content and trigger a rebuild on publish via the CMS's outgoing HMAC-signed webhooks — so a marketer's copy change goes live automatically.

Static microsites: publish and rebuild

Most microsites are perfect candidates for static hosting — small, fast, cheap, secure. The flow:

Marketer edits copy in the CMS
  → CMS fires signed webhook on publish
  → Cloudflare Pages / Netlify rebuilds the microsite
  → Updated static site live in ~1 min

The microsite is static HTML (fast, no server to attack), but the marketer still edits through a real CMS. Best of both.

Honest limitations

• You build the front end. Headless means the CMS provides content; you render it. For a microsite that's usually a small, quick build — but it's not a drag-and-drop page builder. If the marketer wants to build pages visually with no developer, a page-builder tool fits better.
• REST only, no GraphQL.
• No revision history. UnfoldCMS doesn't store past versions.
• You run the server. One lightweight server can host the CMS for many microsites, but it's still yours to run.

When a page builder beats a CMS

Be honest: if the entire point is "marketing builds and edits pages visually with zero developer involvement," a hosted page builder (or a landing-page tool) may fit better than a headless CMS. A headless CMS shines when a developer builds a custom, fast, on-brand front end and the marketer edits the content within it. Match the tool to who's doing the building.

FAQ

What's the best CMS for a microsite? A lightweight headless CMS fits best — it gives marketers a real editor while letting developers build a lean, fast front end. WordPress is usually overkill for a small microsite, and hand-coding blocks non-technical edits.

Can I run multiple microsites from one CMS? Yes. Run a single CMS instance and separate each microsite's content by category or content type, with each front end fetching what it needs. One admin and one server for many small sites — cheaper than a CMS per site.

Should a microsite be static? Often yes — microsites are small, so static hosting is fast, cheap, and secure. Use a webhook to rebuild the static site when a marketer publishes a change.

When should I use a page builder instead? When the goal is for marketers to build and edit pages visually with no developer. A headless CMS is better when a developer builds a custom front end and marketers edit the content inside it.

Bottom line

Microsites live in an awkward middle — too small for WordPress's weight, too content-driven to hand-code. A lightweight headless CMS fits: a real editor for marketers, a lean front end for developers, and one server that can power many microsites at a one-time cost. Go static with webhook rebuilds for speed and security. Just match the tool to the builder — if marketing wants to build pages visually alone, a page builder fits better.
