A multilingual portal with tens of thousands of records overloads a monolithic CMS. The headless approach untethers you: content separate, frontend separate. Contentful is one of the first and most mature headless CMS platforms, built for enterprise tasks. Our team uses it in projects with high performance requirements: 10+ years of experience, 50+ successful projects on headless architecture. Developing a headless site on Contentful achieves TTFB under 100 ms thanks to its built-in global CDN and flexible content model.
According to Contentful, the built-in CDN reduces loading time up to 3 times compared to solutions without CDN.
What Contentful delivers for enterprise projects
The main advantage is a global CDN at all levels. Contentful caches API responses on edge servers, so the end user's TTFB is minimal. In our measurements, this is up to 3 times faster than competitors like Sanity, which lack a built-in CDN. A second plus is the flexible content model: content types, reference fields, media, localization — all configurable via GUI or API. The free plan includes up to 25,000 records and 2 locales, sufficient for small projects. Transitioning to headless architecture reduces infrastructure costs by up to 40%.
Typical Problems We Solve
- Slow page loading due to heavy CMS engines. Contentful delivers only data; markup is generated on the frontend (SSR/SSG/ISR).
- Complexity of synchronizing drafts. We use the Preview API and webhooks for incremental regeneration.
- Content duplication across environments. Contentful provides full environments (development, staging, master).
How We Integrate Contentful with Next.js?
Typical stack: Next.js 14 (App Router) + TypeScript + Tailwind CSS. Content is fetched via the SDK, rendered as React Server Components directly on the server. This gives zero client-side JavaScript for static content.
// lib/contentful.ts import { createClient, type EntryFieldTypes } from 'contentful' export const client = createClient({ space: process.env.CONTENTFUL_SPACE_ID!, accessToken: process.env.CONTENTFUL_ACCESS_TOKEN!, environment: 'master', }) export const previewClient = createClient({ space: process.env.CONTENTFUL_SPACE_ID!, accessToken: process.env.CONTENTFUL_PREVIEW_TOKEN!, host: 'preview.contentful.com', }) For each content type, we create a TypeScript skeleton. This is convenient: the IDE suggests fields, reducing errors during refactoring.
Why Choose Contentful for Next.js?
Next.js pairs perfectly with Contentful: ISR allows pages to be updated after a record is published without a full rebuild. A webhook from Contentful triggers revalidation — the page regenerates on the fly.
// app/api/revalidate/contentful/route.ts import { revalidateTag } from 'next/cache' export async function POST(req: Request) { const secret = req.headers.get('x-contentful-webhook-secret') if (secret !== process.env.CONTENTFUL_WEBHOOK_SECRET) { return Response.json({ error: 'Unauthorized' }, { status: 401 }) } revalidateTag('contentful') return Response.json({ revalidated: true }) } How We Configure Incremental Static Regeneration (ISR)?
The project needs only one webhook for all content types. When a record is published, Contentful sends a POST to /api/revalidate/contentful. We call revalidateTag('contentful') — all pages tagged with this tag are updated on the next request. This is more efficient than rebuilding the entire site.
Note: Contentful offers a free plan (25,000 records, 2 locales) and paid tiers, with cost depending on content volume and required features. Hosting savings can reach 30%.
Comparison of Contentful and Sanity
| Criteria | Contentful | Sanity |
|---|---|---|
| Hosting type | SaaS, cloud | SaaS/self-hosted |
| Built-in CDN | Yes (global) | No (requires setup) |
| GraphQL API | Yes (built-in) | Yes (via Groq) |
| SDK languages | JS, Python, Ruby, PHP | JS, TS, Python |
| Free plan | 25,000 records, 2 locales | 5,000 records, 1 locale |
GraphQL vs REST: Approach Comparison
| Criteria | REST API | GraphQL API |
|---|---|---|
| Field selection | Only whole record | Only needed fields |
| Nested relations | Via include | Directly in query |
| Caching | Built-in CDN | Requires cache header setup |
| Tools | curl, Postman | Apollo, GraphiQL |
For simple pages, REST suffices. For complex dashboards with nested data (e.g., an article with author, tags, comments), GraphQL is more efficient — one request instead of several.
query GetPost($slug: String) { blogPostCollection(where: { slug: $slug }, limit: 1) { items { title content author { name } tags } } } Process Overview
- Content model audit — analyze existing structure, optimize types and references.
- Design — create Content Types, configure localization, environments, permissions.
- Implementation — SDK integration, frontend development, Preview Mode and webhook setup.
- Testing — performance testing (Core Web Vitals), regression testing.
- Deployment — deploy to chosen hosting (Vercel, Netlify, own server).
Scope of Work
- Designing the content model and documenting the schema.
- Integrating the Contentful SDK with your frontend.
- Setting up Preview Mode for editor convenience.
- Webhooks and ISR for instant page updates.
- Admin panel usage instructions and team training.
- 30-day support guarantee after handover.
Estimated Timelines
A basic site with 3–5 Content Types takes 1.5–2 weeks. A complex multilingual project with GraphQL and custom permissions takes 3–4 weeks. Pricing is determined individually after an audit. Contact us for a consultation — we will evaluate your project and propose the optimal solution. Order headless site development on Contentful and get the first page within 2 weeks.
