Best Xperience by Kentico Alternatives in 2026
Xperience by Kentico ships a release every month and bundles a customer data platform with the CMS. It also shipped a high-severity security advisory almost every month of 2026, and still has no A/B testing.
The short answer
HubSpot Content Hub and Contentstack are the strongest Xperience by Kentico alternatives in 2026. HubSpot keeps the marketing suite, with forms, email, automation, personalization and A/B testing built in, at published prices with nothing to patch. Contentstack brings 20-stage workflows, governed AI agents and no security redeploys. SitecoreAI and Optimizely are the suites with native experimentation, Optimizely PaaS DXP and Umbraco keep .NET, Storyblok keeps visual editing, and Kontent.ai suits regulated teams.
Key takeaways
- The security calendar is the reason most teams start looking. Kentico disclosed a critical SQL injection and a multi-factor authentication bypass in May 2026, then a high-severity advisory almost every month after, including an administrator account takeover in September. Fixes ship the same day, but each one is a package update and a redeploy.
- The marketing suite has a hole in it. Xperience by Kentico has no A/B testing and no recommendation engine; experiments run in the visitor's browser through VWO. Optimizely, HubSpot and SitecoreAI test natively. If experimentation is the roadmap, that alone decides the move.
- AI is locked and in preview. AIRA runs only on Kentico-managed Azure OpenAI credits, you cannot bring your own model, and all four agents are preview features. Umbraco, Contentstack and Kontent.ai let you choose the model or audit the agent.
- Keep the .NET team if it is good. Umbraco, Sitefinity and Optimizely PaaS DXP keep your developers productive. HubSpot and the headless platforms need a JavaScript front end or no developers at all, which also fixes the missing TypeScript SDK.
- Price the exit before renewal. Contracts are annual only, increases of up to 25 percent are reported, and custom code does not carry to another platform. The honest comparison puts the rebuild estimate next to the license difference, not just the license.

Our analysts’ take
Xperience by Kentico is the rebuilt mid-market platform on modern .NET. A named Refresh has shipped every month of 2026 under a published 12-month compatibility policy, Page Builder and Email Builder personalize by contact group, Unified Profiles merge visitor records into a customer data platform, and forms, automation and email are included rather than sold separately. SaaS hosting runs in 20 Azure regions with ISO 27001 and SOC 2 Type 2, and reviewers rate support highly. Mid-market .NET teams that want CMS and marketing in one product have reason to stay.
The teams that leave name four gaps. The first is security: a critical SQL injection and a multi-factor authentication bypass in May 2026, three more SQL injections, a cache that exposed protected assets, and an account-recovery flaw in September, most affecting every release back to version 22. The second is experimentation: Kentico's own guide says A/B testing is not supported, and there is no recommendation engine. The third is AI: AIRA runs only on Kentico's Azure OpenAI credits, all four agents are in preview, and there is no audit trail. The fourth is the contract: no published prices, annual-only terms and increases reported up to 25 percent. The only SDK is .NET.
This guide rates nine destinations. Three keep the .NET stack, from the free option to the enterprise suite. Three are managed suites with marketing and testing built in. Three are managed headless platforms, one of them a compliance specialist. The ratings lean on campaign and growth tools, because that is what Xperience customers bought and what the gaps are in, then on security and compliance, marketer self-service and a bill you can forecast.
What to look for
- 1
Testing built in, not bolted on
Ask each vendor to run an A/B test on a page component in the trial, inside the CMS, with results in the same screen. Optimizely, HubSpot and SitecoreAI do this natively. Several alternatives hand it to a separate tool, as Kentico does.
- 2
A security record you can read
Pull each vendor's advisories for the past twelve months and count the ones rated high or critical. Then ask who applies the fix. Managed platforms patch centrally; self-hosted .NET platforms need a redeploy every time.
- 3
AI you control
Decide whether AI must run on your own model keys with an audit trail, or whether vendor-managed credits are acceptable. Umbraco, Contentstack and Kontent.ai pass the first test; SitecoreAI governs its own agents under ISO 42001.
- 4
Pages without a ticket
Have your marketers rebuild a Page Builder landing page in each trial without help. Visual editors that work on the rendered page clear the bar; headless platforms depend on what developers build.
- 5
A bill you can forecast
Xperience is a fixed subscription with annual increases. Ask each alternative for published prices or a renewal cap in writing, the price at double your channels and traffic, and what AI usage costs once the included credits run out.

The shortlist, reviewed
HubSpot Content Hub
The managed replacement for the marketing half of Xperience. Content Hub sits on HubSpot's CRM, so landing pages, forms, email, automation, personalization, A/B testing and attribution are built in, nothing needs patching, and every tier is published. Breeze agents cover the AI story with an audit card per action.
- Best for
- Mid-market B2B marketing teams that chose Xperience for the suite and want the same with experimentation included, at published prices.
- Watch out for
- A rigid content model built around the CRM, weak headless delivery, templates in a proprietary language that leave with nothing, and no role for the .NET team. A/B testing starts at Professional.
- What it costs
- Published. Starter from $15 per month, Professional from $450 per month (three seats), Enterprise from $1,500 per month. AI runs on HubSpot Credits.
Contentstack
The headless platform with the governance and the security record Xperience teams want. Workflows run to 20 stages, publish rules gate releases by branch, language and environment, Agent OS runs AI agents with every action logged, and no vendor CVE is on record. There is no upgrade to plan.
- Best for
- Teams rebuilding the front end on a modern stack that want enterprise workflows, governed AI and no security redeploys.
- Watch out for
- No forms, email or personalization in the product, uptime guarantees are paid add-ons, and health and payment card data are prohibited by contract.
- 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.
SitecoreAI
The enterprise suite for teams that outgrew mid-market. Site Collections isolate each brand, the customer data platform and Personalize are bundled with multi-armed bandit experiments, and Agentic Studio ships 20 prebuilt agents under AI governance certified to ISO 42001. A .NET SDK is included.
- Best for
- Large multi-brand organizations with centralized IT that want personalization, experimentation and governed AI agents in one managed platform.
- Watch out for
- Quote-only pricing with no free tier, implementations of 9 to 14 months, no native commerce, and a record of pulling retirement dates forward to 20 days' notice.
- What it costs
- Quote-only. No published tiers. Customer data platform and Personalize are included in the base license; AI usage has a fair-use cap of 50,000 interactions a year.
Optimizely SaaS CMS
The managed suite built around what Kentico lacks. Visual Builder edits pages, experiences and catalog entries in one place, A/B and multivariate testing with contextual bandits are native, and Opal orchestrates AI agents through MCP. Optimizely handles every upgrade and patch.
- Best for
- Marketing teams that want experimentation and personalization built into a managed CMS and have no need to keep .NET.
- Watch out for
- Quote-only pricing with median contracts near $78,000 a year, rigid auto-renewing terms, experimentation and AI as add-ons, and a February 2026 breach through voice phishing on its own security record.
- What it costs
- Quote-only. Priced on traffic and feature tier, with experimentation and AI as add-ons on credits.
Optimizely PaaS DXP
The .NET suite that fills Kentico's biggest gap. CMS 13 pairs Visual Builder with Content Variations, Web Experimentation sets the market standard for A/B testing with contextual bandits reaching the platform, and Opal ships more than 100 prebuilt agents with a self-hosted MCP server. A HIPAA-enabled variant is actually provisioned.
- Best for
- Enterprise .NET teams, including content-and-commerce operations, that want to keep C# and add experimentation and personalization at scale.
- Watch out for
- Quote-only with median contracts near $83,000 a year and enterprise deals from $250,000, annual increases of 3 to 7 percent in the contract, coarse webhooks, and a CMS 12 to CMS 13 move that is a re-platform.
- What it costs
- Quote-only. No free tier and rigid contract terms. Third-party data puts the median contract near $83,000 a year.
Storyblok
The headless CMS whose visual editor most resembles Page Builder. Marketers click components on the rendered page and rearrange them, the vendor runs hosting and delivery, and first-class SDKs cover React, Vue, Next.js, Nuxt and Astro, which fixes the TypeScript gap. FlowMotion adds workflow automation with approval routing.
- Best for
- Marketing teams with a JavaScript development partner who want visual editing on a managed service with published mid-tier prices.
- Watch out for
- The jump from Growth to Growth Plus is steep, single sign-on and native A/B testing sit on quote-only tiers, and there are no built-in forms, personalization or customer data platform.
- What it costs
- Starter is free; Growth is $99 a month and Growth Plus $349 a month, with usage add-on packs. Premium and Elite are quote-only.
Sitefinity
The other .NET marketing CMS, with A/B testing in the box. Sitefinity Insight is a customer data platform with behavioral segmentation, machine-learning recommendations and testing, SEO tooling generates structured data automatically, and the compliance file adds a HIPAA business associate agreement that names the product to SOC 2 Type 2 and ISO 27001.
- Best for
- Marketing-led mid-enterprise teams in regulated industries that want to stay on Microsoft infrastructure with testing and recommendations built in.
- Watch out for
- Quote-only pricing with reported renewal increases of 40 to 100 percent, five security advisories of its own in June 2026, and self-hosted operations heavier than Kentico SaaS.
- What it costs
- Quote-only. Licensed per server or domain, with editor seats in blocks of five. Third-party estimates run $20,000 to $60,000 a year.
Umbraco
The free .NET CMS. The MIT-licensed core has no license fee at any traffic or seat count, Umbraco Cloud prices are published with monthly billing, and Umbraco.AI lets you bring your own model from about ten providers, which Kentico does not allow. Security fixes ship the same day across three supported lines.
- Best for
- Cost-sensitive .NET organizations and agencies that want low lock-in and will buy marketing features as add-ons when needed.
- Watch out for
- Segmentation, personalization, A/B testing and analytics need the paid Engage add-on, there is no real-time collaboration, and compliance stops at ISO 27001 with no SOC 2 report.
- What it costs
- Free software. Umbraco Cloud from €45 per month, Standard €280, Professional €730.
Kontent.ai
The compliance specialist that former Kentico teams keep choosing. Kontent.ai ships a .NET SDK and holds SOC 2 Type 2, ISO 27001, 27017 and 27018 plus ISO 42001 for AI management, with HIPAA coverage under a business associate agreement. Expert Agents run under human approval with a full audit trail, and several authors edit at once.
- Best for
- Compliance-sensitive .NET organizations moving to headless that need audited AI, co-editing and field-level localization.
- Watch out for
- Pricing is a calculator that ends in a sales quote, there are no marketing features at all, and content cannot be shared across projects.
- What it costs
- Quote-only beyond a free Developer plan. Pricing is calculated on seats, content types, items, languages and environments.
Three exits from Xperience by Kentico, by who you want to keep
Every move off Xperience by Kentico lands in one of three places. The choice depends less on features than on which team you want to keep: the .NET developers, the marketers who run the suite, or neither because the front end is being rebuilt anyway.
Stay on .NET
Umbraco keeps the stack at a fraction of the cost and fixes the AI lock-in. Sitefinity keeps the stack and adds testing and recommendations. Optimizely PaaS DXP keeps the stack and adds the best experimentation in the market. Take this exit if your developers are an asset.
Move to a managed suite
HubSpot Content Hub replaces the marketing half with nothing to run and published prices. Optimizely SaaS CMS and SitecoreAI do the same at enterprise scale, with native testing and governed AI. Take this exit if the monthly security redeploys are what wore you down.
Go headless
Contentstack, Storyblok and Kontent.ai turn the CMS into a content service with real TypeScript SDKs. Personalization and forms come from separate tools. Take this exit if you have the engineering to own the front end and the missing JavaScript tooling was a daily pain.
Questions to settle before you commit
Is experimentation the real reason?
If A/B testing and recommendations are the roadmap, the shortlist is Optimizely, HubSpot, SitecoreAI and Sitefinity. Everything else hands testing to a separate tool.
How many advisories did you redeploy for?
Count the 2026 security releases your team applied and the hours each one took. That is the upkeep budget a managed platform removes. Then read the alternative's advisory history; Optimizely and Sitefinity have records of their own.
What must AI be allowed to do?
If model choice and an audit trail are requirements, Umbraco, Contentstack and Kontent.ai meet them, and SitecoreAI and Optimizely govern their own agents under ISO 42001 or human review. If vendor credits are fine, the question is price once the allocation runs out.
Price the rebuild, not just the license
Custom Kentico code does not carry to any other platform, including a .NET one. Ask two partners for a fixed-scope estimate per destination; the license difference is often smaller than the rebuild difference.
When does the contract renew?
Terms are annual only. Work back from the renewal date: content freeze, launch, redirects and a month of parallel running. If the date is close, negotiate a short extension rather than rushing a platform decision.
Frequently asked questions
Why do companies leave Xperience by Kentico?
Security, missing experimentation and locked AI. Kentico disclosed a critical SQL injection and a multi-factor authentication bypass in May 2026 and a high-severity advisory almost every month after, each needing a redeploy. The product has no A/B testing or recommendation engine, its AI agents are in preview on Kentico-managed credits only, and contracts are annual with increases reported up to 25 percent.
What is the closest alternative to Xperience by Kentico?
Sitefinity is the closest like for like: a .NET marketing CMS with a customer data platform, personalization, forms and, unlike Kentico, A/B testing and recommendations built in. Optimizely PaaS DXP is the enterprise step up on the same stack with market-leading experimentation. Both are quote-only, and Sitefinity's renewals rise steeply.
Is there an Xperience by Kentico alternative with A/B testing built in?
Yes. Optimizely PaaS DXP and Optimizely SaaS CMS set the market standard, with contextual bandits that shift traffic to winning variants. HubSpot Content Hub includes A/B testing from the Professional plan at $450 a month. SitecoreAI bundles multi-armed bandit experiments with its customer data platform, and Sitefinity includes testing in Insight.
Is there a cheaper alternative to Xperience by Kentico for .NET teams?
Umbraco. The MIT-licensed core costs nothing at any traffic or seat count, Umbraco Cloud publishes prices from €45 a month with monthly billing, and a Kentico team is productive in weeks. You also get to bring your own AI model. The trade is that segmentation, personalization and A/B testing need the paid Engage add-on and there is no SOC 2 report.
How long does a migration from Xperience by Kentico take?
Plan on three to six months for a marketing site and longer for multi-channel estates with automation and email in use. Content exports through the GraphQL endpoints and the .NET APIs, but Page Builder widgets, automation flows and custom modules are rebuilt. A .NET destination reuses your team; HubSpot and the headless platforms need a partner or a front-end team.
