What the interviews show. These interviews do not establish an overall winner, and buyers describe the two doing different jobs. Adobe Experience Manager is the CMS of global, multi-brand enterprises already on the Adobe stack: buyers praise how it works with the rest of Adobe and its power at scale, and complain about implementation, the AEM-specific developers routine changes need, and cost. Contentful is the headless CMS buyers move to from monolithic platforms: buyers praise its flexibility and editors publishing on their own once engineers have built the templates, and complain that it still needs engineering and that its price grows with usage. Among the migrations between them described here, more went from AEM to Contentful than the reverse, and the companies that chose AEM over Contentful already had Adobe embedded. Several run both — AEM at the parent company, Contentful for landing pages, acquired businesses or a single brand. The split is the Adobe suite versus a headless layer that fits the rest of the stack.
| Strongest contrast in these interviews | Commentary centres on the Adobe suite around it and the developers it takes | Commentary centres on headless flexibility and editors working without developers, once the build is done |
|---|---|---|
| Buyer pattern in these interviews | Includes global, multi-brand and regulated enterprises already on the Adobe stack | Includes enterprises leaving monolithic platforms, and mid-sized and DTC brands wanting a lighter headless CMS |
| Most-discussed job | Enterprise CMS and digital asset management inside the Adobe suite | Headless CMS |

What buyers say about each platform
Every buyer interview spends its minutes somewhere — praising the thing that won the deal, or flagging the thing that still stings. Map where those minutes go for Adobe Experience Manager and Contentful, and the chart below shows where each platform's praise and complaints concentrate in these interviews — not a ranking of what either can do:
Relative share of buyer commentary by theme in Alium's verified interviews, praise vs. complaint, through October 2026. Widths compare themes within this pair — they are relative, not counts. Each vendor's widths are normalized to its own commentary, because Adobe Experience Manager appears in more interviews.
In their own words
The phrases buyers reach for, verbatim, when they describe each platform:
Adobe Experience Manager
“connects really well with other Adobe products” suite
“AEM is a beast. Super powerful.” power
“you can have a page out in an hour” authoring
“It is very dev heavy” developers
“It is a very locked system” customization
“The tool is very clunky” usability
Contentful
“marketing can do whatever they want” autonomy
“without requiring a developer” editing
“create the content once” headless
“still require engineering work” resources
“technical and rigid” editor
“absurdly expensive the more content” cost
Where Adobe Experience Manager buyers concentrate their praise
AEM buyers concentrate their praise on the Adobe suite around it — it “connects really well with other Adobe products,” says one, and buyers describe Target, Analytics and the asset manager working together — and on power at enterprise scale. Where the templates and components are built well, some buyers describe marketers publishing pages on their own. Its complaints concentrate on implementation and the developers it takes: “it requires a lot of unique engineering experience specific to AEM,” says one buyer, and others describe routine changes waiting on developers who are hard to hire. Buyers also describe editing as clunky, integrations outside Adobe as heavy lifting, and upgrades and cloud migrations as projects of their own. Cost is the other recurring complaint.
Where Contentful buyers concentrate their praise
Contentful buyers concentrate their praise on headless flexibility and editors working without developers: content created once and delivered to web, app and other channels, and editors publishing without a ticket queue. Its complaints concentrate on the engineering it still needs. Buyers describe editors working on their own only after engineers have built the templates or design system, bigger layout changes still needing a developer, an editor some call “technical and rigid,” and a content model whose early choices are hard to undo. Cost is its most common complaint and the reason buyers most often give for leaving it: pricing that grows with content, API calls, locales and team size.
Among the migrations between these two platforms described in the interviews, more companies moved from AEM to Contentful than in the opposite direction. Buyers also describe evaluations that have not yet resulted in a move. Architecture and cost are recurring reasons for considering Contentful, rather than editing experience alone. One company left because “AEM was not the preferred headless choice, and that Contentful, from a headless standpoint was much more forgiving.” Others leaving AEM describe heavily customized builds that became expensive to change. The companies that chose AEM over Contentful already had Adobe embedded in their content and asset management, and one company is weighing AEM to replace Contentful because its parent company standardizes on it. Several run both: AEM at the parent company or as the asset store, Contentful for landing pages, acquired businesses or a particular brand.
Adobe Experience Manager vs. Contentful on cost
Neither price is published here, and contracts vary — what the interviews give is where buyers place the two against each other:
Where buyers place the two against each other on what a content platform costs to run. Positions are relative within this pair, not a price scale, and they say nothing about a third platform.
Every cost remark about AEM in these interviews is a complaint — one buyer calls it among the “most expensive tools on the market” — and buyers add the cost of implementation and AEM-specific developers to the licence. Buyers who compare the two describe Contentful as the cheaper option. Its position moves with use, though: Contentful is priced on usage, and one buyer warns that “Contentful can get very expensive with API calls, locales, and team sizes as the team will grow.” The small brands leaving Contentful in these interviews most often leave on cost.
What buyers wish they'd known
Before picking Adobe Experience Manager
Buyers describe routine changes waiting on AEM-specific developers who are hard to hire, and implementations that set the ceiling for years: rushed or heavily customized builds leave a long tail of fixes. It pays off most inside the Adobe suite; outside it, buyers describe integrations as heavy lifting and the move to the cloud as a project of its own. Our recommendation, not a practice buyers describe: price the development team and the implementation alongside the licence, and check how much of Adobe you will actually run.
Before picking Contentful
Buyers describe editors working on their own only after engineers have built the templates or design system — one says a landing page “doesn't really work unless your engineers devote a huge amount of time building out your design system.” Pricing grows with content, API calls, locales and team size, and early content-model choices are hard to undo. Our recommendation, not a practice buyers describe: price it on the content, locales and teams you expect in two years, not today's.
Four questions the interviews raise
Buyers praise how it works with Target, Analytics and the asset manager; the companies that chose it over Contentful already had Adobe embedded.
Buyers leaving monolithic platforms describe it fitting the rest of a mixed martech stack.
Buyers with an experienced in-house AEM team describe it as powerful; without one, routine changes wait on scarce specialists.
Editors work on their own once engineers have built the templates, and bigger layout changes still need a developer.
Buyers describe a premium licence plus implementation and developer costs.
Priced on usage; buyers describe the bill growing with content, API calls, locales and team size.
Companies running both usually keep AEM as the parent company's site and asset platform.
Companies running both use it for landing pages, acquired businesses or a particular brand.

Pressures visible in these interviews
The complaints these interviews carry sit on both sides: Adobe Experience Manager's are implementation, AEM-specific developers, clunky editing and cost; Contentful's are the engineering it still needs, rigidity in the editor, early content-model choices and pricing that grows with usage.
The clearest distinction in these interviews is what each platform is bought into. AEM is bought into the Adobe suite, and buyers describe its value rising with how much of that suite they run. Contentful is bought as one headless layer in a mixed stack, and buyers describe its value depending on the engineering behind it.
The purchasing question, as we read it rather than as buyers state it, is how much of Adobe you will run and who will build the front ends. A company deep in Adobe with its own AEM developers sits where AEM's praise concentrates; a company building a headless stack with engineers to own the templates sits where Contentful's does.

Common questions
Adobe Experience Manager vs. Contentful: which is better?
Neither is universally better, and buyers describe them doing different jobs. Adobe Experience Manager buyers emphasize how it works with the rest of the Adobe suite and its power at enterprise scale; their complaints center on implementation, the AEM-specific developers routine changes need, and cost. Contentful buyers emphasize headless flexibility and editors publishing on their own once engineers have built the templates; their complaints center on the engineering it still needs and pricing that grows with usage. The better fit depends on how much of Adobe you already run and the developers you have.
What's the difference between Adobe Experience Manager and Contentful?
Adobe Experience Manager is Adobe's enterprise content management system and digital asset manager, built to work with Adobe Target, Analytics and the rest of the Adobe suite. Contentful is an API-first headless CMS: it stores content once and delivers it through APIs to websites, apps and other channels, with the front end built separately. AEM can also deliver content headlessly, but buyers in these interviews choose it for its place in the Adobe suite rather than for headless delivery. In these interviews AEM is most often run by global, multi-brand enterprises already on Adobe, and Contentful by teams moving off monolithic platforms.
Why do companies move from AEM to Contentful?
Buyers in these interviews describe wanting a headless CMS that fits the rest of their stack, and leaving AEM builds that became costly and hard to change. One describes AEM as not the preferred headless choice; another, weighing the move, says Contentful is easier to govern and cheaper. Among the completed migrations described here, more went from AEM to Contentful than the reverse; the companies that chose AEM over Contentful already had Adobe embedded in their content and assets.
Is Contentful cheaper than Adobe Experience Manager?
Buyers who compare the two describe Contentful as the cheaper option, and every cost remark about AEM in these interviews is a complaint about its price. Contentful is priced on usage, though, and its buyers describe the bill growing with content, API calls, locales and team size; cost is the most common reason they give for leaving it. Neither price is published here, and contracts vary.
Can you use AEM and Contentful together?
Yes. Several companies in these interviews run both, most often with Adobe Experience Manager as the parent company's site and asset platform and Contentful for landing pages, acquired businesses or a particular brand. One bank hosts marketing assets in Contentful and publishes them to AEM, its primary site platform.
