Contentful vs Adobe Experience Manager - which CMS is right for you

Contentful vs Adobe Experience Manager

Contentful is a headless, API-first CMS that stores content as structured data and hands it to any front end your developers build. Adobe Experience Manager is a full digital experience platform that bundles content management, asset management, personalization and campaign tooling into one Adobe-governed system.

Pick Contentful when you publish to several surfaces (web, app, in-product, partner sites), you have developers who can own the front end, and you want to choose your own stack around the content layer.

Pick Adobe Experience Manager when you are a large enterprise already running Adobe tooling, you need asset governance and approval workflows across many business units and regions, and you have a platform team funded to operate it.

There is a third answer that neither vendor will give you. If the thing you are actually choosing a CMS for is a marketing site that needs to change weekly, both options put a developer between your marketer and a live page. That is the trade most B2B teams regret within a year.

What Contentful is good at

• Structured content that one team models once and many front ends reuse.
• Clean APIs, so engineers are not fighting the CMS to ship a feature.
• Localization and multi-brand content without duplicating a whole site.
• A lighter operational footprint than a full enterprise suite.

What Adobe Experience Manager is good at

• Deep governance with roles, approvals, audit trails and regional controls.
• Digital asset management at scale, tied into the rest of Adobe.
• Personalization and campaign orchestration for very large catalogs of content.
• A single vendor relationship when procurement wants one company to hold accountable.

Where each platform quietly gets expensive

Both platforms price on enterprise contracts, and the license is rarely the number that hurts. The real cost shows up in the engineering time between "we need this page changed" and the page being changed.

With Contentful, the CMS is only half a system. Someone has to build and maintain the front end, the build pipeline, the preview environment and the component library. That work never ends, and it competes with product work every sprint.

With Adobe Experience Manager, the platform is complete but heavy. Template changes, new components and new page types route through a specialist team or an implementation partner. Marketing files a ticket and waits.

This is the Status Quo Tax. You are not paying it in license fees. You are paying it in campaigns that launch late, pages that never get tested, and a website that reflects last quarter's positioning.

The Agility Gap in plain numbers

Ask your own team two questions before you choose either platform.

1. How long does a new landing page take today, from brief to live?
2. How many of those requests died in the backlog last quarter?

If the answer to the first is measured in weeks, the CMS is not your content problem. It is your go-to-market problem.

How to choose between them

Choose Contentful when

• Content has to feed more than a website, like a product UI or a mobile app.
• You have dedicated front-end engineers and want to keep that control.
• You expect the presentation layer to change more often than the content model.
• You need multi-locale content modeled once and reused everywhere.

Choose Adobe Experience Manager when

• You already run Adobe Experience Cloud and want one governed ecosystem.
• Legal, brand and compliance review every published asset.
• You operate dozens of regional or business-unit sites under one brand system.
• You have budget for an internal platform team, not just a marketing team.

Choose neither when

• The site in question is your marketing and demand-gen site.
• Marketers need to ship pages without a developer in the loop.
• Your bottleneck is speed to publish, not content modeling.

The option most B2B teams should price out first

Before you sign either contract, price the version where marketing owns the site. For a marketing and demand-gen site, a visual platform like Webflow removes the developer dependency for routine publishing, while keeping a structured CMS underneath for blogs, case studies and resource libraries.

We have run this move both ways. M13 came off Contentful and we migrated 438 pages in 21 days, and work that used to take three weeks now takes 24 hours or less. Bigeye moved off Contentful and Gatsby in under 30 days, saved thousands of dollars in development costs, and now moves 10x faster on marketing changes. Uniqode moved over 74 pages and 400 blog articles, and the site serves 200,000+ monthly visitors.

For the business case, the Forrester TEI study commissioned by Webflow modeled a composite organization and found 332% ROI over three years, with $2.12M net present value and payback in under six months. That is Forrester's composite model, not a promise about your site, and it is the right shape of argument to take to a CFO who sees a CMS as a cost line.

What leaving Adobe Experience Manager actually involves

A move off AEM is an architecture project, not a copy-and-paste job. The order that works:

1. Inventory every URL, template and asset, and decide what dies. Most enterprise sites carry years of pages nobody reads.
2. Model the content types you keep, so the new CMS matches how your team actually publishes.
3. Rebuild the component library once, properly, so marketers assemble pages instead of requesting them.
4. Map redirects one to one before launch and keep structured data intact.
5. Migrate content in waves, with the highest-traffic templates first.
6. Launch, then watch rankings and form conversion weekly for the first quarter.

Frequently asked questions

Which one costs more to run

Compare total cost, not license cost. Both are enterprise contracts, and the larger expense for most teams is the engineering and agency time needed to change the site after launch. Add up developer hours per page change, multiply by your real page volume, and the ranking usually changes.

Can marketers publish without a developer in either platform

In Adobe Experience Manager, marketers can publish inside existing templates, but new page types and components need the platform team. In Contentful, marketers edit content fields, and anything that changes layout or adds a section needs a front-end developer. Neither gives a marketer a blank canvas.

Is Contentful a replacement for Adobe Experience Manager

Not on its own. Contentful replaces the content repository. You still need a front end, a digital asset workflow and whatever personalization or campaign tooling AEM was covering. Count those pieces before you call it a like-for-like swap.

How long does a migration take

It depends on page count and how much you keep. For reference from our own work, M13 moved 438 pages in 21 days off Contentful, and Bigeye moved off Contentful and Gatsby in under 30 days. An enterprise AEM estate with heavy governance takes longer, and the inventory step is usually the long pole.

What does a rebuild cost

Ammo publishes pricing on the service pages. Landing pages start around $10K and full builds run $70K-150K+. Ongoing work is Growth Support, starting at $4,800 / quarter for companies under 100 employees, Growth Partner starting at $5,200 / month, and Growth Partner+ starting at $15,000 / month for enterprise scale. Plans are month-to-month, and pricing is subject to change.

Will we lose search rankings if we migrate

Ranking loss comes from broken redirects, changed URL structures and dropped structured data, not from the platform itself. Map every live URL to its new destination before launch, keep page titles and schema in place, and migrate your highest-traffic templates first so you can catch problems early.

We only have a few people on the marketing team. Is enterprise CMS overkill

Usually yes. If your team is under 100 people and the site exists to generate pipeline, the governance features that justify AEM are overhead you will pay for and never use. Choose for your publishing speed, not for the org chart you hope to have in three years.
