TOP PICK

Developers build the framework, marketers edit content in Sanity's visual studio. Best balance of flexibility and ease of use for growing SaaS companies.

Open SourceJavaScript/TypeScript (React)Free (open-source)

Strengths

Hybrid rendering — SSG, SSR, ISR, and client-side in one app
Most popular React framework with massive community
Built-in image optimization, API routes, and middleware

Trade-offs

React learning curve for non-JavaScript developers
App Router introduced complexity with Server Components

Astro + Storyblok

Content-focused framework that ships zero JavaScript by default

Visual page builder for marketers paired with Astro's speed. Storyblok's visual editor lets marketers compose pages from pre-built components.

Open SourceJavaScript/TypeScript (framework-agnostic)Free (open-source)

Strengths

Ships zero JS to the client by default (Islands Architecture)
Use React, Vue, Svelte, or any framework in the same project
Content collections with type-safe Markdown/MDX

Trade-offs

Not ideal for highly interactive apps (designed for content sites)
Smaller ecosystem than Next.js — fewer integrations available

Webflow

Visual web development platform with clean code output

No-code visual builder with CMS. Marketing teams can design, build, and publish pages without developers. Great for early-stage SaaS.

Visual (generates HTML/CSS/JS)Free / $14-39/month

Strengths

Generates clean, semantic HTML/CSS — no code bloat
Full CSS control with a visual interface (like coding without typing)
Built-in CMS with API access and structured content

Trade-offs

Steep learning curve for non-designers (CSS concepts required)
CMS is limited to 10,000 items on the highest plan

Payload CMS + Next.js

TypeScript-first headless CMS that lives in your Next.js app

Self-hosted, code-first CMS that lives in your Next.js app. Full data ownership and custom admin UI. Best for SaaS with developer resources.

Open SourceTypeScript / Node.jsFree (self-hosted) / Cloud plans available

Strengths

Lives inside your Next.js codebase — zero API latency
Config-as-code with full TypeScript type safety
Built-in auth, access control, and file uploads

Trade-offs

Tightly coupled to Next.js ecosystem
Newer platform with a smaller community and fewer plugins

Builder.io + Any Framework

Visual CMS that integrates with any frontend framework

Visual drag-and-drop page builder that outputs to any framework. Marketers build pages, developers maintain the component library.

Framework-agnostic (React, Vue, Angular, etc.)Free / $19+/month

Strengths

Visual editor works with any framework (React, Vue, Svelte, etc.)
Marketers edit pages visually while devs maintain code quality
A/B testing and personalization built into the platform

Trade-offs

Adds SDK dependency and API calls to your frontend
Complex setup compared to traditional headless CMS

How to Decide

For early-stage SaaS without developer resources, Webflow gets you to market fastest

Growing SaaS companies benefit from Next.js + headless CMS for long-term flexibility

If your marketing team ships 5+ landing pages per month, invest in a visual builder like Builder.io or Storyblok

Performance directly impacts ad conversion — static/ISR pages convert better than server-rendered ones

Frequently Asked Questions

Should my marketing site and app be in the same codebase?

Usually no. Keeping them separate lets your marketing team ship pages without waiting for app deploys. Use a subdomain (app.yoursite.com) for the product.

How important is page speed for SaaS?

Critical. Every 100ms of load time reduces conversion by 7% (Akamai). Static-first frameworks like Astro and Next.js with ISR consistently achieve sub-second loads.

What about A/B testing?

Vercel has built-in Edge Middleware for A/B testing. Alternatively, tools like Optimizely, LaunchDarkly, or Statsig integrate with any framework.

How do I track conversions from my marketing site?

Use PostHog, Plausible, or Google Analytics 4 for event tracking. Set up conversion events for signups, demo requests, and pricing page views. Server-side tracking (PostHog) avoids ad-blocker loss.

Should I use a monorepo for marketing site and app?

Usually no. Keep them as separate repos and deployments. This lets marketing ship pages without touching app code, and avoids coupling release cycles. Share components via npm packages if needed.

How do I handle pricing page updates?

Use a CMS-driven pricing section so marketing can update plans, features, and CTAs without deploys. Sanity, Payload, or Contentful work well. Store structured pricing data and render it on your static pages.

What about SEO for SaaS marketing sites?

Static pages rank better than dynamic app routes. Use Next.js or Astro for static marketing pages. Add a blog for long-tail keyword capture and thought leadership. Ensure proper meta tags and schema markup.
