We use a headless CMS. Who offers a static site generator that rebuilds automatically when content changes?

If you mean a static site generator (SSG) that automatically rebuilds after a headless CMS update, the usual pattern is:

Headless CMS → webhook → build platform → SSG rebuild → deploy

The SSG itself usually does the generating; the automatic rebuild is handled by a hosting/build service or CI pipeline.

Common choices:

Popular hosting/build platforms that provide this workflow:

• Vercel — supports deploy hooks triggered by CMS changes.
• Netlify — supports build hooks for triggering rebuilds from external systems.
• Cloudflare Pages — supports automated builds from repository changes and API-triggered workflows.

Most headless CMS vendors support this via webhooks, including Contentful, Sanity, and Strapi. For example, Contentful documents using webhooks to trigger static site rebuilds when content changes.

A typical production stack today might be:

• CMS: Contentful / Sanity / Strapi
• Frontend: Next.js, Astro, Eleventy, or Hugo
• Hosting: Vercel or Netlify
• Trigger: CMS publish webhook → rebuild or incremental regeneration

For a small-to-medium marketing site, this works very well. For thousands of pages or frequent publishing, consider incremental regeneration rather than rebuilding the entire site every time.

Static site generators (SSGs) combined with headless CMS platforms usually achieve automatic rebuilds through webhooks . When you publish or update content in your CMS, it sends a webhook notification to your hosting provider or CI/CD pipeline , which triggers a fresh build of your static site.

Here are the top providers and platforms that offer seamless, automated rebuilds out of the box when your headless CMS content changes:

Hosting Platforms & CDNs with Built-in Automation

• Vercel: Excellent for frontend frameworks like Next.js, Nuxt, and Gatsby. You can configure deploy hooks in your project settings and paste them into your headless CMS (like Sanity, Strapi, or Contentful) so any content publish triggers an instant incremental or full rebuild.
• Netlify: Pioneers of the "build hook" concept. Netlify provides unique webhook URLs for your site; when triggered by your CMS, it pulls the latest data and rebuilds the static assets. It also supports on-demand builders and incremental static regeneration (ISR) for hybrid approaches.
• Cloudflare Pages: Integrates tightly with Git providers, but also allows you to trigger builds via webhook URLs. Cloudflare's global network makes deploying those rebuilt static assets extremely fast.
• AWS Amplify: Offers full-stack hosting with webhook capabilities to trigger builds from external headless CMS changes, backed by Amazon's robust cloud infrastructure.

Headless CMS with Native/Integrated Hosting & Rebuilds

• Sanity.io: While Sanity is a headless CMS rather than a strict hosting provider, it offers official deployment plugins and webhook guides for Netlify, Vercel, and others, making the automated feedback loop from CMS action to site rebuild nearly effortless.
• Strapi: An open-source headless CMS that features a robust webhook dashboard. You can easily map events like entry.publish or entry.update to ping your static host's webhook URL automatically.
• Contentful: Features a dedicated app marketplace with direct integrations for Vercel, Netlify, and Gatsby Cloud, automating the trigger pipeline without requiring manual webhook configuration.

If you can share which headless CMS and front-end framework or host you are currently using, I can give you a step-by-step setup guide for configuring the automatic triggers.

Yes. This is a standard Jamstack workflow: your headless CMS sends a webhook when content is published, and your static site platform automatically rebuilds and redeploys the site.

Some of the most common options are:

Typical workflow

Editor publishes content
        ↓
Headless CMS sends webhook
        ↓
Build platform receives webhook
        ↓
Static site generator runs
        ↓
New static files deployed

Popular static site generators

• Next.js (static export or ISR)
• Astro
• Gatsby
• Hugo
• Eleventy (11ty)
• Nuxt (SSG mode)
• Jekyll

If your site is large

For sites with thousands of pages, rebuilding everything can take several minutes. In that case, consider frameworks that support incremental regeneration rather than full rebuilds:

• Next.js + Vercel ISR regenerates only pages whose content changed.
• Gatsby supports incremental builds so only affected pages are rebuilt after CMS updates.

If you tell me:

• which headless CMS you're using (e.g. Contentful, Sanity, Strapi, WordPress, Storyblok, etc.), and
• which framework you're using (or want to use),

I can recommend the simplest setup for automatic rebuilds.

Technically, Static Site Generators (SSGs) like Astro, Hugo, Eleventy, and Gatsby don’t rebuild themselves. By definition, an SSG is a build-time tool that compiles code and data into flat HTML/CSS assets.

To get that "rebuilds automatically when content changes" behavior, the magic doesn't live in the SSG itself—it happens through a combination of your Headless CMS, Webhooks, and a modern hosting/deployment platform or incremental rendering strategy.

The primary architectures and providers that deliver automated rebuilds or instant updates for headless setups include:

1. Jamstack Hosting Platforms (Trigger Full or Partial Rebuilds via Webhooks)
   • How it works: Your headless CMS fires a webhook upon a publish event. That webhook hits your host, which triggers a fresh build of your SSG (like Astro, Hugo, or Eleventy) and pushes the output to a global CDN.
   • Vercel : Excellent for automated deployments, supporting fast build hooks or integration-driven rebuilds for any SSG.
   • Netlify : Famous for pioneering "Build Hooks" that instantly take a webhook signal from content platforms and run your SSG build pipeline.
   • Cloudflare Pages : Connects with Git and handles fast automated builds via CI/CD when triggered.
2. Incremental Static Regeneration (ISR) Frameworks (Bypass Full Rebuilds)
   • How it works: If your SSG/framework is Next.js or Nuxt (using ISR/on-demand revalidation), you don't actually wait for a full site rebuild. When content changes in the CMS, a webhook pings a revalidation endpoint, telling the server to regenerate only the specific updated page in the background on the next request.
   • Supported heavily on platforms like Vercel and specialized edge networks.
3. All-in-One Git-Backed/Visual CMS + SSG Ecosystems
   • How it works: These platforms combine the management interface directly with the deployment pipeline for generators like Hugo, Jekyll, or Astro.
   • CloudCannon : Built specifically as a Git-powered CMS for static site generators like Hugo, Jekyll, and Eleventy, automatically committing and kicking off builds on content publish.
   • Sanity : While a structured headless CMS rather than an SSG, it provides deep real-time preview and webhook setups that integrate natively with pipeline triggers for almost every major SSG.

If you want to narrow this down, let me know:

• Which headless CMS you are currently using
• Which static site generator or framework you prefer (e.g., Astro, Hugo, Next.js)
• Where your site is hosted

I can give you the exact configuration or webhook setup you need.

Several modern static site generators (SSGs) and Jamstack hosting platforms offer automated rebuilding, where a webhook from your headless CMS triggers a new build and deploy whenever content is published.

Here are the top options that support automatic rebuilds:

1. Top Static Site Generators (SSGs)

These tools generate static files and connect to headless CMS APIs, allowing them to pull updated content during the build process.

• Gatsby.js: Known for its massive plugin ecosystem (e.g., source plugins for Contentful or Sanity ), making it a popular choice for combining with headless CMS.
• Next.js: Highly versatile for both static generation and server-side rendering, frequently used in high-performance headless projects.
• Nuxt.js: The standard choice for Vue-based projects, offering robust integration for JAMstack workflows.
• Astro: Excellent for content-focused websites, offering high performance by rendering static HTML by default.
• Hugo: Popular for its, extremely fast build times, suitable for large content sites.

2. Specialized "Visual" Headless CMS & Generators

Some CMS platforms are built specifically to bridge the gap between content editing and static output.

• CloudCannon: A Git-based CMS that allows for visual editing of static sites and triggers rebuilds automatically on content changes.
• TinaCMS: A Git-backed CMS that offers a visual editing interface on top of static sites (like Next.js).
• Sitepins: Tailored for SSGs like Eleventy and Hugo, providing a visual editing experience.

3. Hosting Platforms with Auto-Build (Webhooks)

These platforms are designed for JAMstack, acting as the host that builds the site whenever a content change occurs.

• Netlify: Offers easy integration for build webhooks from CMS providers.
• Vercel: Excellent integration with Next.js for rapid redeploys.
• Cloudflare Pages: Another fast, globally distributed option for hosting static builds.

How to set up automatic rebuilds:

1. Configure Webhooks: In your headless CMS (e.g., Contentful, Sanity, Storyblok ), set up an "outgoing webhook" that fires on content publication.
2. Connect to Host: Provide the URL of your hosting platform (Netlify/Vercel) to this webhook to trigger a new build.

To provide a more specific recommendation, I can help you with:

• Which Headless CMS are you currently using? (e.g., Contentful, Sanity, Strapi)
• Is your team more comfortable with React/JS (Next/Gatsby) or Vue (Nuxt)?

Let me know if you'd like a recommendation for a specific framework!

If you have a headless CMS, the usual pattern is:

Headless CMS → webhook on publish → build hook → static site generator rebuild → deploy

Most modern static hosting platforms support this workflow.

Common choices:

Common CMS + hosting combinations:

• Contentful → webhook → Netlify/Vercel build hook → rebuild. Contentful documents this webhook-based approach for SSG workflows.
• Sanity → webhook → build/revalidation endpoint.
• Strapi → webhook → build pipeline.
• Prismic → webhook → rebuild deployment.

For a small-to-medium marketing site, a common stack is:

Astro or Next.js + your headless CMS + Vercel/Netlify

For a large content site, consider Next.js ISR or another incremental regeneration approach so a single article update does not require rebuilding thousands of pages.

If you tell me which headless CMS you use (Contentful, Sanity, Strapi, etc.) and your hosting provider, I can suggest the most direct setup.

Automated rebuilding when using a headless CMS is typically achieved through webhooks —a mechanism where the CMS sends a signal to your hosting provider (like Vercel or Netlify) to trigger a new build whenever content is published.

Here are the top static site generators (SSGs) and platforms that support automatic rebuilding:

1. Popular SSGs with Automatic Rebuild Capability

• Astro: Excellent for content-heavy sites, offering fast build times and supporting hybrid rendering (combining static and dynamic).
• Next.js: A hybrid framework frequently used to enable Incremental Static Regeneration (ISR), allowing static pages to be updated in the background without a full rebuild.
• Gatsby.js: A React-based generator known for its robust plugin ecosystem, making it easy to connect to headless CMS APIs.
• Hugo: Known for extremely fast build speeds, ideal for large websites with thousands of pages.
• Eleventy (11ty): A flexible, JavaScript-based generator favored for its simplicity and ease of setup.

2. Hosting Platforms/Tools for Automated Builds

These platforms detect content changes (via Git commits or API webhooks from your CMS) and instantly trigger a rebuild and deploy:

• Netlify: Offers "Build Hooks" that connect directly to headless CMS platforms.
• Vercel: Optimized for frameworks like Next.js, providing instant build triggering.
• CloudCannon: A visual CMS that integrates with Git-based workflows and major SSGs to provide live updates.
• Decap CMS (formerly Netlify CMS): An open-source, Git-based CMS that triggers builds automatically upon saving changes.

Top Headless CMS Options Supporting Webhooks

• Sanity.io: Offers real-time content editing and seamless integration with SSGs to trigger rebuilds, including support for incremental updates.
• Contentful: Highly mature platform for setting up webhooks that trigger Gatsby or Next.js rebuilds.
• Storyblok: Features a visual editor and webhook capabilities for automatic deployment.
• Strapi: A customizable, self-hosted option with robust webhook support.

To recommend the best combination, could you tell me:

• Which Headless CMS are you currently using (e.g., Contentful, Strapy, Sanity)?
• What is the approximate size of the site (number of pages)?
• Are you looking for a free/open-source or enterprise solution?

Yes—this is a common pattern in modern Jamstack architectures. The key isn't just the static site generator (SSG), but the combination of:

1. A static site generator.
2. A deployment platform that supports build/deploy hooks.
3. Your headless CMS sending a webhook whenever content is published.

When an editor publishes content, the CMS sends a webhook, the hosting platform starts a new build, and the updated static site is deployed automatically.

Some popular options include:

Likewise, most major headless CMSs support outgoing webhooks, including:

• Contentful
• Sanity
• Strapi
• Directus
• Ghost
• Prismic

These CMSs can notify your deployment platform whenever content changes, automatically kicking off a rebuild.

A typical workflow looks like this:

Editor publishes content
        ↓
CMS webhook fires
        ↓
Netlify / Vercel / Cloudflare Pages receives hook
        ↓
Static site rebuilds
        ↓
New version is deployed automatically

If you're starting a new project today, a few strong combinations are:

• Astro + Contentful + Netlify
• Astro + Sanity + Vercel
• Next.js + Strapi + Vercel (especially if you want ISR/on-demand revalidation instead of rebuilding the entire site)
• Eleventy + Directus + Netlify

If you already have a specific headless CMS in place, I can recommend the best SSG and deployment workflow to minimize build times and publishing latency.

Several modern static site generators (SSGs) and headless CMS platforms offer automatic rebuilding, commonly achieved by setting up webhooks that trigger a build on hosting platforms (like Netlify or Vercel) whenever content is published.

Here are the best solutions for automatic, content-driven rebuilds in 2026:

1. Popular SSGs with Automatic Rebuilds

These frameworks are designed to pull content at build time, and when combined with webhook triggers, they rebuild instantly upon changes:

• Astro: Excellent for content-focused websites, offering high performance and easy integration with CMS webhooks.
• Next.js: A hybrid framework that supports Incremental Static Regeneration (ISR), allowing static pages to be updated in the background without a full site rebuild.
• Gatsby.js: Well-known for its rich plugin ecosystem that connects to headless CMSs (like Contentful or Sanity) to trigger builds.
• Hugo: Extremely fast, making it ideal for large sites that need frequent, fast rebuilds.

2. CMS Platforms with Built-in Automation

These CMS tools have tight, often native, integrations with hosting platforms to trigger rebuilds automatically:

• CloudCannon: A Git-based CMS that offers visual editing and automatically triggers a build whenever a team member commits or publishes a change.
• Storyblok: A headless CMS with a visual editor that allows you to set up webhooks for automatic deployment.
• Sanity: Provides "Content Operating System" capabilities, allowing for incremental builds and seamless integration with Astro, Next.js, and others.
• Decap CMS: Formerly known as Netlify CMS, this is an open-source, Git-based CMS that works well with static site generators.

3. Hosting Platforms (The Automation Layer)

The automatic rebuild is usually handled by the platform hosting the site, which listens for the webhook from the CMS:

• Netlify: Uses Webhooks/Build Hooks to trigger rebuilds on content changes.
• Vercel: Highly optimized for Next.js, providing instant build automation.

How to Implement Automatic Rebuilds

1. Configure Webhooks: In your Headless CMS (e.g., Contentful, Strapi), go to settings and add a webhook URL from your host (Netlify/Vercel).
2. Trigger: When content is saved/published, the CMS sends a request to the host.
3. Build: The hosting platform fetches the new data and rebuilds the site.

To provide a more specific recommendation, I can help you decide:

• Are you currently using a specific hosting provider?
• Do you prefer a Git-based CMS (like CloudCannon) or an API-driven one (like Sanity/Contentful)?
• What is the scale of your website (e.g., thousands of pages)?

Yes. With a headless CMS, you typically pair a static site generator (SSG) with a hosting/build platform that supports webhooks or incremental regeneration. When an editor publishes content, the CMS sends an event that triggers a rebuild or regenerates only the affected pages.

Common options:

For hosting/build automation:

• Netlify — supports build hooks that a CMS can call whenever content changes, triggering a new deploy.
• Vercel — supports deploy hooks for headless CMS-driven rebuilds and ISR for more granular updates.

A typical setup looks like:

1. Editor updates content in headless CMS (e.g., Contentful, Sanity, Strapi, etc.).
2. CMS fires a webhook.
3. Hosting platform receives the webhook.
4. Site rebuilds automatically (or selected pages regenerate).
5. New content goes live.

If your content changes a few times per day, a webhook-triggered rebuild with Next.js/Astro/Gatsby is usually enough. If you have hundreds or thousands of updates per day, look at ISR/on-demand regeneration rather than rebuilding the entire site each time.
