AEM vs Sitecore vs Optimizely: How to Choose in 2026
The three names on every enterprise shortlist look alike on a feature grid. They are built, sold and run so differently that the grid is the least useful part of the decision.
The short answer
Adobe Experience Manager, SitecoreAI and Optimizely are the three enterprise DXPs most buyers shortlist in 2026, and they are not interchangeable. Choose Adobe Experience Manager for asset-heavy, multi-brand estates already on Adobe. Choose SitecoreAI for personalization, customer data and AI agents bundled in one license. Choose Optimizely for experimentation-led teams and content with commerce. Contentstack, Acquia and HubSpot Content Hub suit buyers who need less suite.
Key takeaways
- All three can run a global, multi-brand website with personalization and AI. The difference is what is in the base license, who runs the infrastructure and which skills your team needs.
- It is not an apples to apples comparison. Each vendor sells two or more products under one brand, so compare named products: AEM as a Cloud Service, SitecoreAI, and Optimizely SaaS CMS or PaaS DXP.
- Adobe sells breadth, Sitecore sells bundling and Optimizely sells experimentation. Pick the one whose strength matches the program you will actually run in the next three years.
- None of the three publishes a price, and the license is often not the largest cost. Implementation, front-end hosting, specialist rates and add-ons usually decide the total.
- If you cannot name the personalization, testing or multi-brand program that needs a suite, you probably do not need one of these three.

Our analysts’ take
Adobe Experience Manager, SitecoreAI and Optimizely have been the default enterprise shortlist for a decade, and analysts keep placing all three near the top. That makes the choice look like a close call between near equals. It rarely is. The three were built on different technology, for different buyers, and they put different things in the box.
The cost of choosing badly is high and slow to show. A team buys the suite with the strongest demo, signs a three-year contract, and discovers in year two that the personalization it paid for needs another license, or that every page change waits on a scarce specialist. By then the migration budget is spent and leaving means doing it all again.
This guide puts the three side by side for a marketing leader, then adds three alternatives for buyers who may not need a full suite. We explain what is the same, what is genuinely different, when each one is the right call, and where cost really sits.
What to look for
- 1
What the base license includes
List the customer data platform, personalization, testing, search, digital asset management and AI agents you expect, and ask each vendor which are in the base contract. The three answer this very differently, and it changes the price more than any discount.
- 2
Running many brands and sites
Count your brands, countries and languages. Ask each vendor to show a shared template with local overrides, central permissions and one change rolled out across sites. All three can do it, with different amounts of setup.
- 3
Who can change a page
Have one of your marketers build a landing page and launch a test in the demo, without the vendor's engineer driving. If every change needs a developer, you will run fewer campaigns than you planned.
- 4
AI that does real work
All three ship AI agents and an official Model Context Protocol server. Ask which agents run on your content today, what governs their output per brand, and how AI usage is metered.
- 5
Cost over three years
Ask for license, implementation, hosting and add-ons over three years, at today's traffic and at double it. A lower first-year quote with a usage meter can cost more than a bigger fixed one.

The shortlist, reviewed
SitecoreAI
The most included of the three. The customer data platform, Personalize, A/B/n testing and Search ship in the base license, Site Collections isolate each brand on shared components, and Agentic Studio offers 20 prebuilt agents under ISO 42001 governance.
- Best for
- Multi-brand enterprises that want personalization, testing and AI agents from one vendor without assembling a stack, including Sitecore XP customers planning their next platform.
- Watch out for
- You still host and run the live front end on Vercel, Netlify or your own servers. Sitecore has pulled retirement dates forward with weeks of notice, and migrations from Sitecore 10 run 9 to 14 months.
- What it costs
- Quote-only with no published tiers. Third-party estimates for all-in annual spend run from $75,000 to more than $500,000, and front-end hosting is extra.
Adobe Experience Manager
The broadest suite of the three. Multi Site Manager pushes content from a central blueprint to hundreds of brand and country sites, AEM Assets and Dynamic Media lead on rich media, and Edge Delivery Services serves pre-rendered pages that load fast.
- Best for
- Global enterprises running many brands and asset-heavy campaigns that already use Adobe Analytics, Adobe Target or Real-Time CDP.
- Watch out for
- Personalization, analytics and the AI agents are each separate Adobe products. Builds take six to twelve months on a proprietary Java stack, and content requests are metered even when the cache serves them.
- What it costs
- Quote-only. Partner guides put entry near $30,000 a year and bundles at $60,000 to $200,000 or more, with first-year services often two to four times the license.
Optimizely PaaS DXP
Optimizely's self-managed .NET edition, now on CMS 13 with Visual Builder. Commerce Connect 15 makes products and catalogs first-class content in the same editor, and audiences, content variations and Web Experimentation support a serious testing program.
- Best for
- Enterprise .NET organizations and B2B or retail sellers that want content and commerce in one editing experience.
- Watch out for
- Moving from CMS 12 to CMS 13 is a re-platform, and self-hosted installs still depend on Optimizely's cloud for Graph and Opti ID. Email, analytics and the customer data platform are separate purchases.
- What it costs
- Quote-only. Median contracts sit near $83,000 a year, entry deals around $36,000 and enterprise bundles from $150,000 to $500,000, before hosting and overages.
HubSpot Content Hub
For organizations that are pricing an enterprise suite to run a marketing site. Content Hub sits on HubSpot's CRM, so landing pages, forms, email, automation, smart content and SEO tools come built in, at published prices with nothing to operate.
- Best for
- Mid-market and B2B marketing teams that need demand generation and fast publishing, not a multi-brand enterprise platform.
- Watch out for
- A content model built around the CRM, weak multi-site governance compared with the suites, and no fit for commerce or intranets.
- What it costs
- Published. Professional from $450 per month (three seats), Enterprise from $1,500 per month. AI runs on HubSpot Credits.
Contentstack
The headless platform for global content teams that need governance more than a suite. Workflows run to 20 stages, publish rules gate releases by branch, language and environment, and Agent OS logs every AI action. There is nothing to upgrade.
- Best for
- Global marketing organizations with strict approval chains that are ready to own a modern front end and buy personalization separately.
- Watch out for
- No commerce or forms of its own, personalization comes from a partner app, and protected health and payment card data are contractually prohibited.
- What it costs
- Free plan, Build at $29 per month, Growth at $299 per month plus $25 per extra user; Enterprise quote-only. AI runs on metered credits.
Optimizely SaaS CMS
The easiest of the three to operate. Visual Builder gives marketers drag-and-drop pages on a headless front end, releases land every one to two weeks with no customer action, Optimizely Graph includes semantic search, and Opal runs AI agents across the editor.
- Best for
- Enterprise marketing teams with a Next.js or Astro front-end team, and organizations standardizing on Optimizely One for experimentation.
- Watch out for
- Which visitor sees which variation is decided by Feature Experimentation or the Optimizely Data Platform, both separate licenses. The JavaScript SDK shipped three breaking major versions in 2026.
- What it costs
- Quote-only. Buyer data puts typical contracts near $78,000 a year with a floor around $36,000, and first-year quotes often cover only 25 to 40 percent of year-one cost.
Acquia
The enterprise home of Drupal and the compliance pick outside the big three. Acquia Cloud is FedRAMP Moderate authorized, holds HIPAA with a business associate agreement and PCI DSS Level 1, and Site Factory runs fleets of hundreds of sites.
- Best for
- Government, healthcare, higher education and global brands running dozens to hundreds of related sites under strict compliance mandates.
- Watch out for
- Quote-only enterprise tiers, a need for Drupal specialists, and vendor-set upgrade deadlines, including Drupal 10 end of support in December 2026.
- What it costs
- Quote-only for the enterprise platform; tier names are public, dollar figures are not.
Is it apples to apples to apples?
Not quite. On a feature grid the three line up row for row, and that is the part that is the same. Underneath, they differ on how they are built, what they bundle and who runs them, and each vendor sells more than one product under its name.
What is the same
All three run many brands, sites and languages from one platform, give marketers a visual editor, offer personalization and testing, ship AI agents with an official Model Context Protocol server, and hold SOC 2 and ISO 27001. All three are enterprise contracts sold through sales, with no published price.
What is different
Adobe sells the widest suite, built on Java, with personalization, analytics and customer data as separate Experience Cloud products. SitecoreAI bundles customer data, personalization, testing and search into one SaaS license but leaves the live front end for you to host. Optimizely leads on experimentation and runs the most for you, but sells personalization and its data platform separately.
Three brands, five products
Adobe Experience Manager comes as a Cloud Service, as Managed Services and with Edge Delivery Services. Sitecore sells SitecoreAI to new buyers and supports Sitecore XP to 2029. Optimizely sells a managed SaaS CMS and a self-managed .NET PaaS DXP with commerce. Compare named products, not brands.
When to choose each of the three
Each suite wins clearly in one situation and is merely competent in the others. Start from the program you will run, not the demo you liked.
Choose Adobe Experience Manager when
You run a large portfolio of brand and country sites, digital assets are central to your marketing, and you already use or plan to buy Adobe Analytics, Target or Real-Time CDP. Nothing else matches its blueprint inheritance and asset management. Choose it over the other two only if you have the budget and the Adobe specialists to build on it.
Choose SitecoreAI when
You want customer data, personalization, testing and AI agents from one vendor, on one contract, without stitching products together. It suits multi-brand enterprises with regulated data needs outside the US federal market, and Sitecore XP estates whose partners already know the model. Choose it over the other two when bundling matters more than best-in-class testing or asset depth.
Choose Optimizely when
Experimentation is a program with analysts and a backlog, not an occasional test, or your site is really content plus commerce. Pick SaaS CMS for a managed headless build with a JavaScript front end, and PaaS DXP for a .NET team that needs catalogs in the editor. Choose it over the other two when testing and operations matter more than multi-brand depth.
When to look outside the top three
A good share of the buyers who shortlist these three need fewer than half of what they would pay for. These are the signals that a different kind of platform will serve you better.
Your content goes to many channels
If the job is governed content for websites, apps and other channels, with personalization handled elsewhere, a headless platform such as Contentstack or Contentful gives you enterprise workflow without a suite to run.
Compliance decides the shortlist
If you are in government, healthcare or higher education and run a fleet of related sites, Acquia on Drupal brings FedRAMP Moderate hosting, HIPAA support and Site Factory, with a far larger talent pool than any of the three.
It is really one marketing site
If the estate is a corporate site and a few campaign pages, HubSpot Content Hub gives marketers forms, email and automation at published prices. You will spend in a year what one of the suites costs to implement.
You are a mid-market .NET shop
If you want to stay on .NET without an enterprise contract, Xperience by Kentico bundles content, personalization, forms and email in one product, and Umbraco offers a free core with published cloud prices.
Where cost fits into the equation
Cost decides more of these deals than features, but rarely in the way the first quote suggests. The license is one of four lines, and on all three platforms it is often not the largest.
License and what it meters
Adobe meters content requests, counted even when served from cache, with a yearly true-up. Optimizely meters traffic and API usage, and SitecoreAI reports usage annually with an AI fair-use cap. Ask each for the price at double today's traffic.
Implementation and specialists
First-year services for Adobe often run two to four times the license. SitecoreAI programs commonly reach $150,000 to $350,000 for mid-market builds and over $1 million for large ones. Optimizely projects typically take three to six months.
Hosting and running it
Adobe and Optimizely SaaS host the live site. SitecoreAI hosts authoring and delivery APIs, but your front end runs on Vercel, Netlify or your own servers, with enterprise Vercel alone near $35,000 a year.
Add-ons that complete the demo
Adobe Target and Real-Time CDP, Optimizely Feature Experimentation and its Data Platform, and Sitecore's Scrunch answer engine tooling are separate lines. Ask for every product in the demo to be itemized on the quote.
Exit cost
Content in Adobe's repository has no standard export, Optimizely contracts auto-renew on rigid terms, and Sitecore sets deprecation dates on its own schedule. Price the way out before you sign the way in.
Frequently asked questions
Is AEM better than Sitecore?
Neither is better overall. Adobe Experience Manager is stronger on digital asset management and running very large site portfolios, especially inside Adobe Experience Cloud. SitecoreAI includes customer data, personalization and testing in its base license, which Adobe sells separately. Choose on which of those your program depends.
Is Optimizely cheaper than AEM or Sitecore?
Often at entry, not always in total. Optimizely contracts start around $36,000 a year with a typical deal near $78,000, while Adobe and SitecoreAI usually start higher. Add-ons for experimentation and its data platform, plus overages, close much of the gap, so compare three-year totals.
What is the difference between Sitecore XP and SitecoreAI?
Sitecore XP is the older self-hosted .NET platform, supported to 2029 but receiving no new features. SitecoreAI is the SaaS successor to XM Cloud, with customer data, personalization, testing and AI agents in one license. Moving from XP to SitecoreAI is a re-implementation, not an upgrade.
Which is easier for marketers to use, AEM, Sitecore or Optimizely?
All three now offer a visual editor: Universal Editor in Adobe Experience Manager, Page builder in SitecoreAI and Visual Builder in Optimizely. The real difference is setup, so ask a marketer on your team to build a page and launch a test in each demo without help.
Do I need an enterprise DXP at all?
Only if you will run multi-brand governance, personalization or experimentation at scale. Many organizations that shortlist Adobe, Sitecore and Optimizely run one marketing site, where HubSpot Content Hub or a headless CMS such as Contentstack delivers most of the value at a far lower cost.
