CMS for SaaS Marketing Sites

Most SaaS founders pick a CMS once and regret it for the next three years. The marketing site that ships with your MVP gets buried under 50 plugins, slow page loads, and a monthly bill that climbs every time you launch a new feature page. This is for SaaS founders evaluating which CMS to put in front of your product.

TL;DR: For a SaaS marketing site, three CMS options actually fit: UnfoldCMS (one-time license, includes a themed frontend, $39+), Sanity (powerful but starts at $99/mo + overages), and Astro + Markdown (free, ultimate control, requires you to build everything). Skip WordPress. Skip Webflow if your team is technical. Skip Notion-as-CMS — it breaks at scale.

What a SaaS Marketing Site Actually Needs

The SaaS marketing site has different requirements from a corporate site, an e-commerce store, or a media publication. Get clear on what you actually need before evaluating tools.

Core requirements for a SaaS marketing site:

• Fast page loads (Core Web Vitals matter — they affect Google ranking and signup conversion)
• Easy editing for non-developers (your designer or marketer needs to ship changes without filing a ticket)
• SEO basics: meta tags, OpenGraph, sitemap, schema, redirects
• Blog with categories and authors
• Landing pages with custom layouts (feature pages, comparison pages, integration pages)
• Forms (waitlist signups, demo requests, contact)
• A/B testing or split testing for headline/CTA experiments
• Predictable monthly cost — not a bill that climbs with traffic

Not actually needed for most SaaS sites:

• Real-time multi-cursor collaborative editing
• Per-environment dev/staging/prod separation
• Multi-language content management (until you have actual international demand)
• Advanced workflow approvals
• Per-seat editor pricing tiers

If you only need the core list, you're paying for capabilities you'll never use when you pick a $300/month enterprise CMS.

Quick Comparison: 6 CMS Options for SaaS Marketing Sites

The Honest Shortlist for SaaS

Out of the six options above, three are realistic for most SaaS founders. The rest are situational.

1. UnfoldCMS — Best for Self-Hosted SaaS Marketing Sites

Pricing: $39 (Core) → $799 (Agency, unlimited). One-time. No metering. Pair with $5–$20/month shared PHP hosting.

Why it fits SaaS specifically:

• Built-in marketing essentials: SEO records, redirects, blog, forms, comments. Features WordPress requires 5+ plugins to deliver.
• Includes a themed frontend (Aurora theme). You can launch a marketing site without writing a frontend, then swap to a custom Astro/Next.js frontend later via the REST API.
• One-time pricing means your CMS bill doesn't grow with your MRR.
• Self-hosted means you own the data, the uptime, and the deploy cycle.

For technical founders: REST + GraphQL APIs feed your custom frontend. No vendor lock-in. We covered the developer story in What Makes a CMS Developer-Friendly.

For non-technical founders: The admin is built on shadcn/ui — 50 components, 183 admin pages. Editing posts and pages doesn't require developer help.

Where it loses: No real-time collaboration. Smaller community than WordPress or Webflow. You handle hosting (a $5/month shared host or a Hetzner CX22 at €4.51/month works fine).

2. Sanity — Best for Funded SaaS with Marketing Engineers

Pricing: Free tier (3 users, 10k documents). Growth at $99/month per project. API requests metered — overages bill at $1 per 100k requests. A Series-A SaaS with marketing engineers and active blog publishing typically hits $200–$500/month.

Why it fits some SaaS:

• Studio (Sanity's editor) is genuinely best-in-class. Marketing teams that need real-time collaborative editing love it.
• Visual Editing — click any element on your live site, edit it in Studio.
• Mature Astro/Next.js integrations (next-sanity, @sanity/astro).

Why you might not pick it:

• Per-project pricing. If you're an indie founder with a SaaS + blog + docs site, that's potentially three projects.
• API metering means preview deploys and CI builds eat your quota. We covered the cost reality in UnfoldCMS vs Sanity.
• GROQ is Sanity-specific — knowledge doesn't transfer to other CMSes.

Pick if: You're a funded SaaS with marketing engineers, you want real-time collaboration as a daily workflow, and you have approved budget for $200–$2,000/month in CMS spend.

3. Astro + Markdown — Best for Solo Technical Founders

Pricing: Free. Hosting on Vercel/Netlify free tier handles most SaaS marketing sites until you hit serious scale.

Why it fits some SaaS:

• Zero JS by default. Fastest possible page loads — Core Web Vitals will be perfect.
• Markdown content collections in src/content/ — every change is a git commit.
• Total control over output, styling, and behavior.
• $0/month at most traffic levels.

Why you might not pick it:

• No editor UI. Your marketer needs to learn git, or you need to build a custom CMS layer (defeats the purpose).
• No image optimization out of the box for non-developers — uploads via git are awkward.
• Adding new page types means writing code, not clicking a button.

Pick if: You're a solo technical founder, you'll do all the marketing site editing yourself, and your designer is comfortable filing pull requests instead of editing in a CMS admin.

The Situational Options

These three aren't always wrong — they're just narrower fits for SaaS.

Webflow: Powerful visual builder, $19–$235/month. Great for non-technical founders who want full design control without writing CSS. Loses on: developer integration is weak, content modeling is limited compared to a real CMS, prices climb fast as your traffic grows.

WordPress: Free, technically possible, deeply not recommended for new SaaS. The plugin marketplace is a security and maintenance liability. 250+ plugin vulnerabilities are disclosed weekly in 2026. You'll spend Friday afternoons patching plugins instead of shipping product. Use a real CMS instead.

Notion-as-CMS: Tools like Super.so and Potion turn Notion into a website. Editing is amazing — your team already uses Notion. But: limited custom layouts, slow page loads (Notion's API isn't built for production traffic), no real SEO control, and it breaks at any kind of scale. Fine for a one-page launch site. Not fine for a real SaaS marketing site by year two.

Cost Comparison: 3-Year TCO for a SaaS Marketing Site

The pricing model matters more than the monthly fee. Here's what a typical SaaS marketing site costs over 3 years on each platform.

UnfoldCMS hits a 30× cost advantage over Sanity by year 3 for the typical marketing site.

What to Look for in a SaaS Marketing CMS

Specific evaluation criteria — score the CMSes you're considering against these.

1. Does it ship with SEO records built in? Title tags, meta descriptions, OpenGraph, schema, sitemap. WordPress requires Yoast. Sanity requires custom setup. UnfoldCMS includes them by default.
2. Does it ship with redirects? When you change URLs (and you will), broken redirects tank SEO. Built-in redirects table > plugin-based redirects.
3. Can your designer edit without you? The admin should let a non-developer publish a blog post or update a feature page without filing a PR.
4. What's the API for? If you're going custom-frontend, the API needs to be REST or GraphQL with predictable schemas. GROQ-only (Sanity) means lock-in.
5. What's the cost trajectory at 100k pageviews/month? Most managed CMSes meter API requests; your CDN solves visitor traffic, but build hooks and preview environments still hit the API.
6. What happens if the vendor pivots? Webflow, Contentful, and Sanity have all changed pricing dramatically in the past 3 years. Self-hosted = no surprise repricing.

Decision Framework

Pick by team and budget shape — not by feature checklist.

Choose UnfoldCMS for SaaS if:

• You want one-time pricing instead of monthly bills
• You need a CMS that ships with marketing essentials (SEO, redirects, forms) built in
• You want to either use the included frontend OR connect a custom Astro/Next.js frontend via REST/GraphQL
• Your team is OK running a $5–$20/month PHP host alongside your SaaS infrastructure

Choose Sanity for SaaS if:

• You're funded and have marketing engineers
• Real-time collaborative editing is a daily workflow for your team
• Budget allows $200–$2,000/month in CMS spend

Choose Astro + Markdown if:

• You're a solo technical founder doing all the editing yourself
• Total control matters more than UX for non-technical editors
• You're comfortable making every content change a git commit

SaaS Marketing Site Setup with UnfoldCMS

The 30-minute version of how this actually works.

1. Install UnfoldCMS on a $5/month host

UnfoldCMS runs on any PHP 8.3 host. Hetzner CX22 (€4.51/month), DigitalOcean droplet ($6/month), or even shared hosting like Hostinger ($3/month) all work. Upload via SFTP, point your domain, run the installer.

2. Pick a theme or use your own

The Aurora theme ships with UnfoldCMS — built on Tailwind v4, sections for hero, pricing, FAQ, testimonials, blog, contact form. Edit colors and content via the admin. If you want a fully custom design, swap it for your Astro/Next.js frontend hitting the REST API.

3. Create the standard SaaS marketing pages

/                — Homepage with hero, features, pricing, FAQ
/pricing         — Pricing page with plan cards
/blog            — Blog index
/blog/[slug]     — Blog post template
/integrations    — Integrations gallery
/changelog       — Product changelog
/about           — Team and story
/contact         — Contact form (built-in, no Typeform needed)

UnfoldCMS handles all of these as page or post content types. SEO records, OpenGraph, and schema generate automatically.

4. Add a custom frontend (optional)

For SaaS teams that want full design control, point your Astro or Next.js frontend at the REST API:

// astro.config.mjs — fetch posts at build time
const res = await fetch(`${UNFOLD_API_URL}/api/blog/posts`);
const { data: posts } = await res.json();

We covered the integration patterns in Best CMS for Next.js and Best CMS for Astro.

5. Wire up forms

UnfoldCMS has built-in forms — contact, waitlist, demo request, newsletter. No Typeform subscription needed. Submissions land in the admin and trigger email notifications.

6. Connect your analytics

Drop your GA4, PostHog, or Plausible tag into the theme settings. UnfoldCMS doesn't impose its own analytics — use what your SaaS team already uses.

Total time from install to live marketing site: half a day for technical founders, a full day including content writing.

What to Migrate If You're Already on Something Else

Two common migration paths for SaaS founders changing CMSes.

WordPress → UnfoldCMS: Half-day project. Export WordPress XML, import via UnfoldCMS API, set up redirects, swap DNS. The full process is in How to Migrate from WordPress to UnfoldCMS.

Contentful → UnfoldCMS: One-day project. Export with Contentful CLI, transform JSON, import via REST. Particularly worth it if you're paying $300+/month and don't need real-time collaboration. Step-by-step in How to Migrate from Contentful to UnfoldCMS.

Webflow → UnfoldCMS: One-day project. Export Webflow CMS as CSV, transform to UnfoldCMS post format, import. Frontend rebuild required (Webflow's HTML doesn't transfer cleanly).

Notion-as-CMS → UnfoldCMS: Half-day. Notion API export → CSV → REST import. Often the right move once you outgrow Notion's API rate limits.

If you'd rather not do this yourself, the Migration Concierge service is $499 and ships in 7 days.

FAQ

What's the cheapest CMS for a SaaS marketing site? Astro + Markdown if you're a solo technical founder (free). UnfoldCMS Core ($39 one-time + $10/month hosting = $159 first year) if you want a real admin UI. Both beat Webflow ($348/year) and Sanity ($1,188/year) by a wide margin.

Do I need a headless CMS for my SaaS marketing site? Only if you're already running a custom Astro/Next.js/Remix frontend. For most early-stage SaaS, a CMS that ships with a themed frontend (UnfoldCMS, Webflow) is faster to launch and easier to iterate on.

Can I use the same CMS for my marketing site AND my product blog? Yes — and you should. Splitting them across two tools means double the auth setup, double the SEO work, and double the editor confusion. UnfoldCMS, Sanity, and Contentful all handle marketing pages + blog in one workspace.

How do I handle staging/preview environments? UnfoldCMS supports content drafts (saved but not published) and a ?preview=1 query parameter on the API for fetching unpublished content. For full preview environments, run a second UnfoldCMS instance pointed at a separate database — total cost ~$10/month extra.

Will my SaaS marketing site rank well on Google with UnfoldCMS? Yes if you ship the basics: fast page load, schema markup (built in), descriptive meta tags (built in), valid sitemap (built in), redirects (built in), and content that matches search intent. The CMS itself isn't a ranking factor — the output it produces is.

What about A/B testing landing pages? For server-side A/B, use Vercel's middleware or an edge worker. For client-side A/B, use PostHog, GrowthBook, or Statsig. UnfoldCMS doesn't include native A/B testing — but the API exposes everything you need for any external tool.

Can my designer edit without knowing markdown or HTML? Yes. UnfoldCMS uses a rich text editor with formatting buttons, image embedding, and link management. Your designer doesn't see markdown unless they click the source code toggle.

What about international/multi-language SaaS sites? UnfoldCMS supports multi-language content via separate post entries linked by a locale group. For SaaS founders without active international demand, ship in English only first — premature i18n is a common time sink.

Methodology

Pricing data is from each vendor's public pricing page as of May 2026. 3-year TCO calculations assume one-site-per-CMS at typical SaaS marketing site usage (under 100k pageviews/month, 5 editors, 1 blog with biweekly posts). Stack and feature evaluations reference each CMS's official documentation and direct testing on production SaaS marketing sites.

Try UnfoldCMS for Your SaaS Marketing Site

If UnfoldCMS sounds like the right fit, the live demo takes 90 seconds — browse the admin, create a post, see how the API responds. Pricing is one-time and all tiers include the full source code. The Core tier at $39 is enough to test the full product on a real SaaS marketing site.

For more comparisons, see UnfoldCMS vs WordPress, vs Contentful, vs Sanity, or the Best CMS for Next.js breakdown if you're committed to a custom frontend.

If a different CMS in this list fits your project better, that's a fine answer. The point of this page is to give you the information to decide, not to pretend UnfoldCMS is the answer for every SaaS team. See also: Best CMS for SvelteKit.
