Best Headless CMS for Astro in 2026: 7 Options Compared

Astro is content-first by design, and its own content collections handle Markdown well for a single developer. Once you have multiple editors, structured content types, or content that should change without a deploy, you want a headless CMS. This guide compares seven that work well with Astro.

We make Cosmic, so weigh our take on it accordingly. Competitor prices were checked against each vendor's pricing page on November 2, 2026, and platforms are listed alphabetically.

Quick comparison

What matters for Astro specifically

Static or server output. Most Astro sites build static pages and fetch content in frontmatter or getStaticPaths(). In that mode, any CMS with a JSON API works equally well, and what matters is triggering a rebuild on publish through a webhook to Vercel, Netlify, or Cloudflare. If you use an SSR adapter, you can also fetch on request and preview drafts live.

Official integration versus SDK. Storyblok, Sanity, and DatoCMS ship Astro integrations that register components or a preconfigured client. Others, Cosmic included, use a plain JavaScript SDK or fetch in frontmatter. The integration saves some setup; the SDK route adds no framework-specific dependency to upgrade.

Visual editing on Astro is limited by design. Astro renders HTML, not a reactive app, so in-place editing is more constrained than on React frameworks. Storyblok notes that its bridge refreshes the page on save rather than updating in real time, and Sanity's click-to-edit overlays need SSR.

Islands. If you render CMS rich text inside React, Vue, or Svelte islands, check that the CMS's rich text format has a renderer for that framework, or ask for HTML or Markdown output.

The options

Contentful

• Astro fit: the contentful JavaScript SDK in frontmatter; Astro's docs include a Contentful guide.
• Pricing: Free is for non-commercial use only (10 users, 100,000 API calls a month). Lite is $300/month. Salesforce completed its acquisition of Contentful on September 1, 2026.
• Watch for: a large jump from free to paid for a typical Astro marketing site.

Cosmic

• Astro fit: @cosmicjs/sdk in frontmatter or getStaticPaths(), with webhooks to trigger rebuilds. Astro's official docs include a Cosmic guide, and there is a ready-made Simple Astro Blog template. Cosmic is a REST API, so it behaves the same in static, server, and hybrid output.
• Beyond content: AI agents that draft and publish content, an MCP server for Cursor and Claude Code, and imgix-powered image URLs that work well with Astro's image handling.
• Pricing (verified November 2026): Free is $0 with 1 Bucket, 2 team members, and 1,000 Objects. Builder is $99/month, Team $299/month, Business $499/month. Each plan includes a set number of team members, and additional members are $29 each per month.
• Watch for: there is no @cosmicjs/astro integration and no drag-and-drop page builder; you map content to your own components.

DatoCMS

• Astro fit: @datocms/astro provides components and utilities, including responsive images and structured text.
• Pricing: Free covers 1 collaborator and 300 records. Professional is €149/month billed annually (€199 monthly).
• Watch for: the Free plan's 300-record limit.

Payload

• Astro fit: Payload's admin panel runs as a Next.js app, so an Astro site consumes its REST or GraphQL API from a separate deployment. Astro's docs include a Payload guide.
• Pricing: MIT-licensed and free to self-host. Payload Cloud has paused new project deployments since Figma acquired Payload in June 2025.
• Watch for: you run two apps (Astro and the Payload admin) plus a database.

Sanity

• Astro fit: @sanity/astro exposes a preconfigured client through the sanity:client module and can embed Sanity Studio on a route. Visual editing needs SSR and @astrojs/react.
• Pricing: Free includes 20 seats, 2 public datasets, and 10,000 documents. Growth is $15 per seat per month.
• Watch for: the Studio is configured in code, and GROQ is one more query language for the team to learn.

Storyblok

• Astro fit: @storyblok/astro is an official integration that maps CMS components to Astro components. Storyblok markets itself as an official CMS partner for Astro.
• Pricing: Starter is free for 1 seat. Growth is $99/month with 5 seats; Growth Plus $349/month with 15 seats.
• Watch for: on Astro the Visual Editor refreshes on save rather than updating live.

Strapi

• Astro fit: REST and GraphQL APIs; Astro's docs include a Strapi guide.
• Pricing: the open source edition is free to self-host. Strapi Cloud starts at $35 per project per month (Starter), with Pro at $90 and Business at $450.
• Watch for: Strapi Cloud no longer has a free plan, and self-hosting means running the Node server and database.

How to choose

• Editors build pages visually: Storyblok.
• You want a custom editing app and have SSR: Sanity.
• You want everything self-hosted: Strapi or Payload.
• You want GraphQL and image components: DatoCMS.
• You want a plan-based price, a REST API that works in every output mode, and AI agents built in: Cosmic.
• Astro content collections are enough if one developer edits Markdown in git. Many sites start there and add a CMS when editors join.
