Jamstack Explained: A WordPress User's Guide

You've heard buzzwords like "Jamstack," "headless," "static sites," and "serverless." Everyone seems excited about them, but what do they actually mean?

This guide explains Jamstack in terms WordPress users will understand.

---

What Is Jamstack?

Jamstack stands for:

• JavaScript

• APIs

• Markup

But the acronym is less important than the concept:

Jamstack is an architecture where your website is pre-built as static HTML files and served directly from a CDN.

Compare this to WordPress:

WordPress

Jamstack

Every visit runs PHP code

Pages pre-built at deploy time

Database queried per request

No database at runtime

Server does work for each visitor

CDN serves static files

Dynamic by default

Static by default, dynamic when needed

---

How WordPress Works (Traditional)

When someone visits your WordPress site:

1. User requests page
2. Server receives request
3. WordPress (PHP) boots up
4. Plugins load
5. Theme loads
6. Database queries run (50-200+ per page)
7. HTML assembled from pieces
8. Response sent to user

This happens on every single page view (without caching).

---

How Jamstack Works

When someone visits a Jamstack site:

1. User requests page
2. CDN serves pre-built HTML file
3. Done

The HTML was already built before anyone visited. It just... already exists.

When Does Building Happen?

When you:

• Deploy your site

• Update content through a CMS

• Trigger a rebuild via webhook

Modern platforms rebuild in seconds to minutes, then deploy to CDN globally.

WordPress Concepts → Jamstack Equivalents

Let's translate:

Posts and Pages

WordPress: Stored in database, assembled on request

Jamstack: Written as Markdown/MDX files, built into HTML

---
title: "My Blog Post"
date: "2026-02-05"
author: "John Doe"


My Blog Post

Content goes here in Markdown format.

Theme

WordPress: PHP templates that generate HTML

Jamstack: Components (React, Vue, Svelte) or static templates

// React component
function BlogPost({ title, content, date }) {
  return (
    

      
{title}

      {date}
      
{content}

    

  );
}

Plugins

WordPress: PHP extensions that add features

Jamstack:

• npm packages (for build-time features)

• API services (for runtime features)

• Serverless functions (for custom logic)

WordPress Plugin

Jamstack Alternative

Yoast SEO

Built into code + next-seo

Contact Form 7

Formspree, Netlify Forms

Google Analytics

Analytics script + Plausible

WooCommerce

Shopify API, Snipcart

Comments

Giscus, Disqus

Database

WordPress: MySQL stores everything

Jamstack:

• Content: Files (Markdown) or Headless CMS

• User data: Modern databases (Supabase, PlanetScale)

• No database for basic content sites

Media Library

WordPress: Uploads stored on server

Jamstack:

• Images in project folder

• Or CDN services (Cloudinary, Imgix)

• Optimized at build time

Admin Dashboard

WordPress: wp-admin for everything

Jamstack:

• Content: Headless CMS (Sanity, Contentful, Decap)

• Code: GitHub + deploy preview

• Analytics: Separate service

---

The "Static" Confusion

"Static" doesn't mean "frozen" or "unchanging."

Static means: HTML is pre-built before visitors arrive

Not static:

• Content can change (rebuild to update)

• Pages can have interactivity (JavaScript)

• You can have user login, comments, payments

• Dynamic data can load client-side

Think of static as "pre-prepared" not "permanent."

---

Adding Dynamic Features

"But I need dynamic features!"

Jamstack handles this through:

1. Client-Side JavaScript

Interactive elements run in the browser:

• Sliders and carousels

• Form validation

• Custom calculators

• Real-time updates

2. APIs and Services

External services handle specific functions:

• Stripe for payments

• Algolia for search

• Auth0 for authentication

• Mailchimp for newsletters

3. Serverless Functions

For custom backend logic:

// api/contact.js - runs on demand
export default function handler(req, res) {
  // Process form submission
  // Send email
  // Return response
}

4. Incremental Static Regeneration (ISR)

Pages can regenerate on-demand:

• First request builds fresh page

• Subsequent requests get cached version

• Background rebuilds keep content fresh

---

Why Is It Faster?

WordPress Speed Bottlenecks

1. PHP processing - Code runs per request

2. Database queries - 50-200+ queries per page

3. Plugin overhead - Each plugin adds latency

4. Distance to server - Far visitors = slow

Jamstack Speed Advantages

1. No processing - HTML already exists

2. No database - Nothing to query

3. No plugins - All built at deploy time

4. Global CDN - Files served from nearest location

Result: 3-10x faster page loads

---

Why Is It More Secure?

WordPress Security Issues

• Attack surface: PHP, database, admin, plugins

• 97% of attacks target plugin vulnerabilities

• 30,000 sites hacked daily

• Constant updates required

Jamstack Security

• No database to breach

• No PHP to exploit

• No plugins with vulnerabilities

• No admin panel to brute force

• HTML files can't be "hacked"

Result: Virtually unhackable for typical attacks

2. Commit to Git

3. Automatic deploy starts

4. Live on CDN in 30-60 seconds

Option B: Headless CMS (content-friendly)

---

Is Jamstack Right for You?

✅ Great for:
