The best headless CMS for Astro

What is Astro?

Astro is a modern web framework built around a simple idea: deliver fast pages by sending minimal JavaScript to the browser.

Astro renders pages to static HTML by default, then hydrates only the interactive parts of the UI, meaning it attaches JavaScript behavior only where needed. This reduces the amount of client-side JavaScript compared to fully client-hydrated applications, and makes it ideal for content-driven sites with limited interactivity.

Why Astro is so fast

Islands architecture with selective hydration

Astro uses an islands architecture: pages are rendered as static HTML by default, and only specific components become interactive. Instead of hydrating the entire page, JavaScript is loaded only for the components that require user interaction.

For example, a marketing page may consist mostly of static content such as headings, text, images, and pricing tables. If the page includes an image carousel, only that carousel component is hydrated and receives client-side JavaScript. The rest of the page remains pure HTML.

By avoiding full-page hydration and sending JavaScript only where it is needed, Astro reduces client-side code, keeps bundles smaller, and improves performance, especially for content-heavy websites.

A strong fit for content-driven websites

Because most pages remain static HTML and only small interactive islands require JavaScript, Astro is particularly well suited for marketing websites, documentation, blogs, and SEO-driven content platforms where performance and crawlability are critical.

Getting started

Creating an Astro website, blog, or landing page project with React Bricks takes just a few minutes. Run:

# pnpm
pnpm create reactbricks-app@latest

# npm
npm create reactbricks-app@latest

# yarn
yarn create reactbricks-app

Then choose an Astro starter and you are ready to build.

How React Bricks fits with Astro

Astro focuses on performance and selective hydration. React Bricks complements it by providing a visual headless CMS built around React components and TypeScript. Developers define the allowed structure in code, editors compose pages visually, and the design system remains safe.

Component-defined content structure

With React Bricks, content structure is defined directly inside your React components. Developers specify the allowed props and constraints in TypeScript, and the CMS stores structured JSON content that matches those definitions.

The result is alignment between content, UI, and architecture. There is no disconnect between abstract schemas and real components, because the components are the schema.

For Astro projects, you can also define the interactivity strategy for each brick directly in the brick schema. For example, you can chooseload to load JavaScript immediately, idle to load it when the browser is idle, or visible to load it only when the component enters the viewport.

Visual composition with brand safeguards

Editors compose pages directly on the frontend using predefined bricks. Content is assembled visually, while layout rules and brand constraints remain enforced in code.

This ensures speed and autonomy for marketing teams without compromising the corporate image or the integrity of the design system.

AI generation within your component system

React Bricks can generate entire pages as structured content, using your bricks as the building blocks. AI does not produce raw HTML or React code; it generates structured JSON content that conforms to your component definitions.

The generated content is immediately available inside the visual editor, where content teams can review, refine, and modify it just like any other page. AI accelerates production, but editors remain in full control.

When using the MCP server, pages can also be generated programmatically and asynchronously. This enables scalable content strategies such as long-tail SEO campaigns, where large numbers of keyword-focused pages are created while remaining consistent with brand and architectural constraints.

Enterprise-ready governance

As your content operation grows, React Bricks supports collaboration, roles and permissions, approval workflows, multiple environments, SSO, ISO/IEC 27001 certified security practices, and optional self-hosting.

This makes it suitable not only for fast marketing sites built with Astro, but also for organizations that require compliance, governance, and operational control.

When to choose Astro vs Next.js

Astro and Next.js can both be excellent choices, but they usually shine in different scenarios:

Choose Astro when

• You're building a content-first site and want minimal client-side JavaScript.
• You want interactivity as islands, rather than an SPA everywhere.
• You want a simple setup and extremely fast pages.

Choose Next.js when

• You need a full-stack framework where frontend and backend logic live in the same project.
• Your application relies on API routes, authentication, or server actions tightly integrated with the UI.
• You are building a product or web application with complex routing, personalization, or dynamic user-specific content.

Why React Bricks fits Astro so well

• Developers keep control: content blocks are real components with constraints defined in code, preserving layout integrity and brand rules.
• Editors move fast: pages are assembled visually within a structured system.
• Performance stays high: Astro delivers HTML-first pages and hydrates only what requires interactivity.
• Content production scales: full-page AI generation and asynchronous MCP workflows support long-tail SEO strategies, while Approval Workflow, Collaboration, Localization, and Scheduled Publishing ensure governance and coordinated publishing across teams and markets.
