What's the best CMS for an Astro website?

There isn't a universal best — there are best fits. For non-technical authors who need a visual editor, TinaCMS or Sanity. For a Git-native team that wants the CMS to write directly to the repository, Decap. For agencies managing many clients with structured content, Sanity or Storyblok. For a small business site where the owner emails changes once a month, no CMS at all is often the right answer. The decision depends on who edits the content, how often, and whether the editing pattern justifies the setup overhead.

Do I need a CMS for Astro?

Probably not, if you're a small business with one person editing the site occasionally. Astro's built-in content collections handle Markdown and MDX files directly — you can edit content in any text editor, push to Git, and the site rebuilds. For developers and tech-fluent founders, this is the simplest setup. A CMS becomes worth the setup overhead when non-technical people need to edit content regularly without involving a developer. The honest rule: if you'd rather email changes to your developer, you don't need a CMS. If you'd rather log into a browser and edit yourself daily, you do.

TinaCMS is a Git-based open-source CMS with a visual editing interface. Like Decap, it commits content changes to your Git repository as Markdown or JSON files. Unlike Decap, Tina has a more polished editing experience, real-time visual preview, and a richer block-based editor. The open-source version is free and self-hosted; Tina Cloud (the managed service) adds collaboration features, media management, and authentication from $0 to $599+/month depending on tier. For Astro sites that need a serious editorial workflow, Tina is usually the right choice.

Is Sanity good for Astro?

Yes — Sanity pairs cleanly with Astro and is the right choice when content needs to be structured, queryable, and shared across multiple sites or applications. Sanity stores content in a hosted database (the Sanity Content Lake) and exposes it via a query API. Editors use Sanity Studio, a customisable React-based editing interface. The free tier supports small projects; paid plans start at $99/month for serious use. Sanity is the heavyweight choice — more setup, more capability, the right answer when content management is a non-trivial part of the product.

Can I use WordPress as a headless CMS for Astro?

Yes, and several large Astro sites do exactly this. WordPress runs in the background as a content database with the WPGraphQL or REST API exposed; Astro fetches the content at build time or on request and renders it. The advantage is the WordPress editing experience for authors who already know it, paired with the speed and architecture benefits of Astro on the front end. The disadvantage is that you're maintaining a WordPress backend with all its update and security overhead, which partly defeats the reason most people leave WordPress in the first place. It works, but it's rarely the optimal answer.

How much does an Astro CMS cost?

Free, in most cases. Decap is open-source and self-hosts on your existing hosting (Netlify or Cloudflare Pages free tier). TinaCMS open-source is free; the managed Tina Cloud free tier covers most small business needs. Sanity's free tier supports up to 3 users and 10,000 documents — enough for most projects. The paid tiers start when you need team collaboration, role-based permissions, or higher document/asset limits — typically $20-$100/month for serious use. The cost is almost always lower than the WordPress licensing + plugin renewal stack the CMS replaces.

Best CMS for Astro: An Honest Comparison for 2026

Astro doesn’t ship with a CMS, and that’s deliberate. You pick the editing experience that fits how your content actually gets made. The four serious options for 2026 — Decap, TinaCMS, Sanity, Storyblok — pair cleanly with Astro and each suit a different audience. The fifth option is the honest one most articles skip: no CMS at all, content as files, changes by email. For a one-person small business it’s often the right answer. Here’s how to pick.

Do You Actually Need an Astro CMS?

Before picking a CMS, ask whether you need one. Astro’s built-in content collections handle Markdown and MDX files directly — you write content in plain text files, push to Git, the site rebuilds. For a developer-fluent owner or a tech-comfortable founder, this is the simplest possible setup and the one I’d argue for first.

The case for a CMS is straightforward: non-technical people need to edit the site regularly, without involving a developer or learning Markdown. If that’s not your situation, a CMS adds setup overhead and a service to maintain in exchange for capability you don’t use. The case against the CMS is simpler still: most small business sites get edited monthly at most, and the email-me-changes pattern handles that volume cheaper, faster, and with no extra moving parts.

A CMS is the right answer when content editing is a routine part of the business. It’s the wrong answer when you’re installing it because the proposal said you should.

I’ll name the trade-off honestly: my Pay Monthly £49/month service includes content updates because most of my clients want the result, not the editing interface. They email me a change, I make it in an hour, the site stays fast and consistent. For that pattern, no CMS is the right answer. If your editing pattern is different — daily content updates, a marketing team posting weekly, anywhere non-technical authors need autonomy — keep reading.

Four Serious CMS Options for Astro

Four CMS choices genuinely pair cleanly with Astro in 2026. The rest of this piece is the working underneath each one — what it is, what it does well, what it costs, and when it’s the right answer.

Decap CMS — Git-Native, Free, Self-Hosted

Decap (formerly Netlify CMS, renamed in February 2023) is the simplest pairing for an Astro site. It runs entirely in the browser as a single static page you add to your repository at /admin/. Authors log in via GitHub OAuth or Netlify Identity, edit content through a visual interface, and Decap commits the changes directly to your Git repository as Markdown files. Astro picks up the changes on the next build and the site updates within seconds.

What it does well:

Free, open-source, no vendor lock-in
Content lives in your Git repository as Markdown files — same format Astro reads directly
Works on top of any existing Astro deployment (Netlify, Cloudflare Pages, Vercel)
Zero database, zero server-side runtime, zero ongoing infrastructure cost
Familiar Markdown editor with image upload and basic field types

What it doesn’t:

The editing interface is functional but not polished — visual preview is limited
Real-time collaboration isn’t a first-class feature
The block-based editing experience modern editors expect isn’t there
Project maintenance has been slower since the Netlify rename — not abandoned, but quiet

When to choose it: small Astro sites where the author is technically comfortable, doesn’t need rich collaborative editing, and values the no-cost / no-lock-in profile. Documentation sites, personal blogs, simple business sites with one editor.

Cost: £0 forever for the CMS itself. You pay only for your existing hosting, which is typically free on Netlify or Cloudflare Pages for small business traffic levels.

TinaCMS — Git-Based with a Polished Editor

TinaCMS is the choice when you want a Git-based CMS but you also want the editing experience to feel modern. Like Decap, Tina commits content changes directly to your Git repository as Markdown or JSON. Unlike Decap, the editing interface is genuinely good — real-time visual preview, block-based editing, structured content schemas, and a smooth authoring experience that non-technical editors actually enjoy using.

What it does well:

Real-time visual preview — you see the rendered page as you edit
Block-based content authoring (much closer to Notion or Webflow than to a wiki)
Structured content schemas with TypeScript types
Git-native — content stays in your repo as files, no lock-in
Open-source core, with optional Tina Cloud for collaboration features

What it doesn’t:

More setup than Decap — schemas, field definitions, preview wiring
Tina Cloud (the managed service) is the path to collaboration features; self-hosted Tina is workable but more configuration
The editor is heavier than Decap — larger JavaScript bundle, more browser work

When to choose it: Astro sites where the content is structured (multiple page templates, repeating blocks, complex schemas), the editor is non-technical, and the editorial workflow matters. Marketing sites for SaaS products, agency sites with multiple editors, content-heavy blogs.

Cost: Open-source self-hosted is free. Tina Cloud free tier supports two editors and basic features. Paid tiers start at $29/month for teams, scaling to $599+/month for enterprise.

Sanity — Hosted, Structured, Queryable

Sanity is the heavyweight choice. Instead of storing content as files in your Git repository, Sanity stores content in a hosted database (the Content Lake) and exposes it via a query API. Astro fetches the content at build time (for static pages) or at request time (for dynamic pages), then renders it. Editors work in Sanity Studio, a fully customisable React-based editing interface that runs in the browser.

What it does well:

Structured content first — define your schemas, get strong typing and validation
Real-time collaboration with multiple editors
Powerful query language (GROQ) for fetching exactly the content you need
Same content can serve multiple sites, apps, or platforms — one source of truth
Mature, well-funded, used by serious companies (Figma, National Geographic, Nike marketing)

What it doesn’t:

More moving parts — your content lives on Sanity’s servers, not your repo
Initial setup overhead is non-trivial — schemas, studio configuration, API integration
Hosted-only — there’s no self-hosted version of the full Sanity platform
Vendor risk is real (mitigated by content export, but the dependency exists)

When to choose it: when content is a non-trivial part of the product. Multiple websites sharing content. An editorial team with multiple authors. Structured content with relationships (articles linking to authors linking to categories linking to series). Anywhere the content management problem genuinely deserves a serious tool.

Cost: Free tier supports up to three users and 10,000 documents — enough for many small projects. Growth tier $99/month adds collaboration and more capacity. Enterprise pricing scales from there.

Storyblok — Visual Editor with Component Slots

Storyblok occupies similar ground to Sanity but with a different design philosophy. Instead of code-first schemas, Storyblok leans heavily on a visual page builder where editors compose pages from pre-defined block components. The editor sees the page as it’ll render, drags blocks around, and the content lives in Storyblok’s hosted backend.

What it does well:

Visual page builder that non-technical editors find immediately intuitive
Strong real-time preview — the editor literally edits the rendered page
Component-based content model maps cleanly to Astro’s component model
Excellent for marketing teams who want to compose landing pages without involving developers

What it doesn’t:

Hosted-only; same vendor dependency as Sanity
Pricing scales up more aggressively than Sanity for larger content volumes
The visual page builder can encourage component proliferation — discipline required

When to choose it: marketing-led sites with frequent page composition work. SaaS marketing sites, agency client portals, anywhere editors want to assemble pages visually without a developer in the loop.

Cost: Free tier supports one user and limited content. Paid tiers from €99/month for teams, scaling to €4,500+/month for enterprise.

WordPress as a Headless CMS for Astro

Several large Astro sites use WordPress as a headless backend — WordPress runs the editing interface, Astro fetches the content via WPGraphQL or the REST API and renders the front end. The pattern works and the editing experience is familiar to anyone who’s used WordPress before.

The honest framing: this option exists, and for organisations with deep WordPress editing experience and large existing content libraries, it can be the right transitional step. But it carries the maintenance burden of WordPress (PHP updates, security patches, plugin compatibility) into a stack that was supposed to escape that burden. Most projects that consider headless WordPress are better off either staying on WordPress entirely or migrating the content to a purpose-built headless CMS during the Astro rebuild.

The exception is content-heavy publishers (50+ active authors, thousands of posts, complex editorial workflows) where the WordPress editor is genuinely the right tool and the speed gain from a static front end justifies running both systems.

The No-CMS Option (Astro Content Collections)

Astro’s built-in content collections deserve a section, because for many sites they’re the right answer and the article you find on Google often skips them.

A content collection is a folder under src/content/ containing Markdown or MDX files. Astro reads them as typed, queryable content at build time. You can define schemas with Zod, get TypeScript types for free, query collections from any page, and treat the content as part of your codebase.

For a single-author blog, a documentation site, a small business marketing site, or any project where the author is comfortable editing text files and using Git, content collections are the simplest setup that works. There’s no CMS to deploy, no admin route to secure, no third-party service to depend on. The content is the codebase. The editing tool is whatever text editor you prefer.

The Pay Monthly model I run for clients works this way — content lives in the repository, I edit it when clients send changes, the site rebuilds, the change is live in two minutes. For most small businesses, the per-month cost of “developer makes my changes” is lower than the per-month cost of a CMS subscription plus the time the owner spends learning it.

How to Pick an Astro CMS — Decision Tree

Five questions, in order.

One: Will non-technical people edit the site regularly? If no, use Astro content collections — no CMS needed. If yes, continue.

Two: Does the content need real-time collaboration between multiple editors? If yes, Tina Cloud, Sanity, or Storyblok. If no, Decap is enough.

Three: Is the content structured (multiple types, relationships, repeating blocks) or essentially flat (pages and posts)? If structured, Sanity or TinaCMS with proper schemas. If flat, Decap is enough.

Four: Is the editor visually-led (drag, drop, compose pages) or content-led (write structured fields)? If visually-led, Storyblok. If content-led, the others.

Five: What’s the budget profile? If £0/month is the constraint, Decap or self-hosted Tina. If £30-100/month is acceptable, Tina Cloud or Sanity Growth. If hundreds per month is fine, any option works.

The most common right answers in practice:

No CMS — small business with monthly editing, developer-supported
Decap — solo or small-team Astro site with technical-comfortable editor
TinaCMS — structured content, non-technical editor, real editorial workflow
Sanity — content as product, multi-site or multi-platform, serious editorial team

The Honest Verdict

For a UK small business considering an Astro build, the CMS question is usually answered backwards from the editing pattern. If you’re going to edit the site once a month, you don’t need a CMS — content collections plus a developer relationship is faster and cheaper. If you’re going to edit weekly with non-technical collaborators, TinaCMS is the natural fit. If you’re building a content-heavy publication or a multi-site presence, Sanity is the serious tool.

The mistake most prospects make is installing a CMS because the original proposal said the site should have one, then never using the visual editor because emailing the developer is faster anyway. The CMS becomes a thing they pay for and never log into. If that’s the trajectory, skip the CMS and put the saved setup time into better content instead.

If you’re not sure which side of the line your business sits on, the Astro Website Design page covers what’s included in a typical build (content collections, no CMS by default) and the contact form is the route to ask about a specific setup. The right answer depends on who’s actually going to edit the site, how often, and whether the editor wants a tool or wants the result.
