Adobe Experience Manager or Sanity: what does AEM cost you that a headless CMS would not?

How do Adobe Experience Manager and Sanity differ at the core?

Adobe Experience Manager (AEM) is a digital experience platform (DXP) built around pages and components, while Sanity is a hosted content database, the Content Lake, edited in a Sanity Studio configured in code. AEM's headless models "are defined by information architects in the AEM Content Fragment Model editor" (Adobe headless introduction, October 2026); a Sanity schema "consists of JavaScript (or TypeScript) objects" (Sanity schemas docs, October 2026). Sanity serves GROQ (Graph-Relational Object Queries) from a cached content delivery network (CDN) if you opt in (Sanity CDN docs, October 2026).

What do AEM and Sanity cost as of October 2026?

Adobe Experience Manager (AEM) has no published price, while Sanity Growth costs $15 per seat a month and Enterprise is custom pricing, as of October 2026 (Sanity pricing; Sanity for Startups, October 2026). Adobe's AEM Sites page offers "Book a demo", and its pricing page offers "Get pricing" but no figure (Adobe AEM Sites; Adobe AEM Sites pricing, October 2026), so you get a quote and your contract sets the billing term.

Adobe does publish its unit: AEM Sites as a Cloud Service is licensed against content requests, and requests through its headless APIs (application programming interfaces) "still count as content requests" (Adobe content requests, October 2026). How Adobe counts content requests explains that meter. Sanity's Growth plan is "Pay-as-you-go for higher usage" (Sanity pricing, October 2026), and what Free and Growth include lists the quotas where overage starts.

What does AEM cost you that Sanity doesn't?

Adobe Experience Manager (AEM) carries four cost lines that Sanity either lacks or prices in public (Deploi's judgment):

1. A quote-only license. On Cloud Service it's metered on content requests, headless calls included (Adobe content requests, October 2026).
2. Java and OSGi skills. AEM projects are Maven builds that package OSGi (Java module framework) bundles (Adobe project structure, October 2026), a specialist stack next to JavaScript.
3. On 6.5 on premises, your own servers and Adobe's support clock. Core support ends 28 February 2027 and extended support, critical fixes only, 28 February 2028 (Adobe support timelines, October 2026); Adobe recommends an upgrade to 6.5 Long-Term Support (Adobe 6.5 Long-Term Support FAQ, October 2026).
4. On Cloud Service, a refactor and Adobe's cadence. "/apps and /libs are immutable at runtime" (Adobe notable changes, October 2026), so code and configuration change only through a deployment; features activate monthly, and versions over six months old "require scheduled updates with Adobe assistance" (Adobe roadmap, October 2026).

What does Sanity cost you that AEM doesn't?

Sanity costs you a front end and, for the governance AEM (Adobe Experience Manager) includes, an Enterprise plan. A headless content management system (CMS) "never has a frontend presentation layer attached" (Sanity headless guide, October 2026), so your team builds and hosts the site or app that renders Sanity content. Sanity's AEM page says it "removes the need for specialized AEM expertise" (Sanity AEM comparison, October 2026), but that front end still needs JavaScript developers. Three AEM capabilities map to Enterprise items on Sanity, as of October 2026:

• Assets. Sanity's Media Library, its nearest match to AEM Assets, "is available as an addon for certain Enterprise plans" (Sanity Media Library docs, October 2026).
• Access control. "Custom roles, custom content resources, and cross-dataset references require an Enterprise plan" (Sanity multi-tenancy guide, October 2026).
• Campaigns. Content Releases, the nearest match to AEM Launches (Adobe Launches, October 2026), "is available on certain Enterprise plans" (Sanity Content Releases guide, October 2026); on Growth, a scheduled draft "holds only this one" document (Sanity Scheduled drafts guide, October 2026).

Sanity's packaged workflow engine isn't generally available yet. Sanity Workflows "is in early access" with pre-1.0 packages (Sanity Workflows docs, October 2026), so don't count on it to replace the workflow and governance Adobe lists for AEM authoring (Adobe Edge Delivery overview, October 2026).

Which fits multi-site and multi-brand teams, AEM or Sanity?

Adobe Experience Manager (AEM) fits teams that roll the same pages out to many sites, and Sanity fits teams that share structured content across brands. AEM's Multi Site Manager (MSM) "enables you to use the same site content in multiple locations" through live copies of a blueprint, each "maintained by synchronization actions as defined by the rollout configurations" (Adobe Multi Site Manager, October 2026). Sanity has no live-copy feature: you run one project, one Sanity Studio with a workspace per brand, and datasets chosen by access, which is how one Sanity setup runs several brands.

The gap is who can edit and share what, as of October 2026:

• Editor access. Growth includes 2 datasets and 5 roles, and its Contributor role has "Read and write access to draft content within all datasets" (Sanity roles docs, October 2026), so limiting editors to one brand inside one project needs Enterprise custom roles.
• Shared content. A reference from one dataset to a document in another needs cross-dataset references, which "is available on certain Enterprise plans" (Sanity cross-dataset references, October 2026).
• Shared pages. Without live copies, a page that runs on every site is one document all front ends query, or a copy per site you keep in sync yourself (Deploi's judgment).

Where does AEM win, and where does Sanity win?

Adobe Experience Manager (AEM) wins on one-vendor breadth and page authoring; Sanity wins on content reuse, developer control and published pricing (Deploi's judgment from the sources cited).

AEM wins when:

• You want pages, assets and delivery from one vendor: Sites, Edge Delivery Services and Assets appear as licensed solutions on one dashboard (Adobe License dashboard, October 2026).
• Authors want to write in Word or Google Drive and publish through Edge Delivery Services, which Adobe calls "document-based authoring" (Adobe Edge Delivery overview, October 2026).
• The same pages roll out across many sites through Multi Site Manager live copies.

Sanity wins when:

• Content feeds apps and several front ends, because GROQ (Graph-Relational Object Queries) queries "join information from multiple documents" in one request (Sanity GROQ docs, October 2026).
• Developers want the content model in version control, because the schema is code.
• You want a published price, plus Visual Editing and the Presentation tool on every plan (Sanity pricing, October 2026).

How hard is it to move from AEM to Sanity?

Moving from Adobe Experience Manager (AEM) to Sanity means a new front end and a remodeled content set, because Sanity has no AEM importer and AEM's export routes give you component JSON, not Sanity documents. Sanity's migration skill for AI agents has an AEM guide (Sanity agent toolkit, October 2026), and Sanity calls the skill "agent-scaffolded, not fully automated" (Sanity August releases, October 2026). Adobe's knowledge base lists those export routes, including the Assets HTTP application programming interface (API) and page data read "by appending .model.json to the published page URL" (Adobe export methods, October 2026). Your team scripts the conversion, so the work grows with the number of component types, live copies and redirects (Deploi's judgment). Our AEM to Sanity migration plan maps each AEM structure to Sanity and orders the steps.
