Challenges with Kentico
Key pain points
Here’s the reality check about Kentico. It isn’t cheap. Licensing, implementation, and support can feel like a CFO jump-scare. And while the interface is friendly at first glance, once you get into migrations, upgrades, or deeper customisation, things get… heavy.
Major version updates can introduce breaking changes, permissions get messy at scale, and multi-tenant setups mean one bug can take down every project sharing the stack. The docs and community aren’t as deep as the open-source world either, so when something goes wrong, you’ll likely need a developer rather than a forum thread to save you. If you can absorb the overhead and like Corporate Memphis art, go ahead. But before you go ahead, give us a call, and we will try to set up a better solution for you.
Steep learning curve
Kentico’s power comes with complexity. Newcomers and smaller teams often need time (and developers) to actually start working.
High cost for licenses and maintenance
Licensing and maintenance can add up quickly, which makes Kentico a harder sell for startups or smaller organizations.
Upgrades can get messy
Major version jumps, migrations, or deep API changes sometimes introduce breaking changes, which, trust us, is not fun if your site has years of custom logic.
UI feels dated at scale
As projects grow, the dashboard can get cluttered and less intuitive. It works, but it’s not winning design awards, unless you are still competing in 2015.
Limited community support.
Support exists, but the ecosystem isn’t as loud or as active as WordPress (not our first choice), Webflow, or headless-first platforms like Sanity.
Customizations risk impacting all sites
In multitenant setups, a poorly built custom feature can impact every site in the cluster, which means you can't move or change a single line of code, unless you love 404 messages.
Benefits of Craft CMS
Key advantages
Craft CMS is one of those platforms we genuinely respect from a developer standpoint. The content modelling is best-in-class for a traditional CMS. You define sections, entry types, and fields with real precision, and the authoring experience maps cleanly to the underlying data structure. If your content team needs a CMS that actually reflects how the site is built, Craft delivers that better than most. The Twig templating layer is clean and predictable, and the admin UI is fast and intuitive once editors get past the initial learning curve.
Where Craft really shines is in the middle ground between simple marketing sites and full-blown enterprise builds. It's flexible enough to handle complex content architectures without the bloat of something like WordPress, and the built-in GraphQL API means you can use it headless if you want to pair it with a modern frontend. The plugin ecosystem is smaller but noticeably higher quality than what you'd find in WordPress, and the Composer-based workflow means your whole project can live in version control properly.
We've seen agencies build genuinely impressive work on Craft, especially for content-heavy sites where editorial workflows matter. If your team includes developers and you want a CMS that rewards careful architecture, Craft is a solid choice. It's not trying to be everything to everyone, and that focus shows.
That said, we'd typically recommend a headless CMS like Sanity for most of the projects we take on. Craft is at its best when you're comfortable with PHP and want a tightly integrated traditional or hybrid setup. If you're building on Next.js or a modern JavaScript stack, you'll find more natural fits elsewhere.
Exceptional content modelling
Craft's field and section system gives you precise control over your content structure. You can model complex relationships between content types without fighting the CMS.
Clean authoring experience
The admin panel is fast, well-organized, and maps directly to how content is structured. Editors can work efficiently once they understand the layout.
Built-in GraphQL API
Craft ships with a native GraphQL API, so you can use it headless without plugins or workarounds. It's deeply integrated and well-documented.
Composer-based modern workflow
Everything is managed through Composer, so your project, plugins, and dependencies all live in version control. Deployments through CI/CD pipelines work smoothly.
Higher quality plugin ecosystem
The plugin store is smaller than WordPress but the quality bar is noticeably higher. Plugins are better maintained and less likely to break your site on update.
Granular user permissions
Built-in role and permission management is detailed and flexible. You can lock down exactly what each editor can see and do without needing third-party plugins.
Common questions
Kentico to Craft CMS migration FAQs
Answers to the most common questions about Kentico to Craft CMS migration
How much does a Kentico migration typically cost?
Kentico migrations are enterprise-scale projects. For a site with 1,000 to 10,000 pages, expect the migration itself to run 8 to 16 weeks of development time. The cost depends on how deeply you've customised Kentico's marketing automation, e-commerce, and workflow features. Simple content-only migrations are faster, but most Kentico installations have years of custom .NET logic that needs to be rebuilt or replaced. We've seen total migration budgets range from $30,000 to $150,000 depending on scope, which still often pays for itself within 18 months through reduced licensing and maintenance costs.
Why are companies migrating away from Kentico?
Licensing costs are the initial trigger for most conversations we have. Kentico's annual fees add up fast, especially when you include maintenance, hosting, and the cost of .NET developers to keep it running. But the deeper issue is agility. Major version upgrades introduce breaking changes that can destabilise sites with years of custom logic. The admin UI feels dated as projects scale. Multi-tenant setups carry real risk since one bad customisation can take down every site in the cluster. Teams eventually decide the operational overhead isn't worth it.
What's the biggest challenge when migrating from Kentico?
Untangling the all-in-one features. Kentico bundles marketing automation, e-commerce, analytics, workflows, and content management into one platform. When you migrate away, each of those capabilities needs a new home. Content goes to your new CMS, email automation might move to a tool like Resend or Customer.io, and e-commerce might need a dedicated platform. We map out every feature your team actually uses before writing a single migration script, because the biggest risk is discovering a dependency mid-project that nobody documented.
How much does Craft CMS cost for an agency managing multiple sites?
The costs add up quicker than most agencies expect. The Solo tier is free for single-user projects, Team is $279 per project, and Pro is $399 per project. Both paid tiers carry a $99 annual renewal fee. If you're running 10 client sites on Pro, that's $3,990 upfront plus $990 per year in renewals before you've paid for a single plugin. Popular plugins like SEOmatic, Blitz (caching), and Navigation run $99-$199 each. Factor in PHP hosting ($20-$100/month per site depending on traffic) and the total per-project cost lands between $500 and $1,500 in year one. It's reasonable for individual projects but the aggregate cost across a portfolio is where agencies feel the squeeze.
What are the hidden costs of running Craft CMS?
Beyond licensing, three costs catch teams off guard. First, PHP hosting. Craft needs PHP 8.2+, MySQL or Postgres, and proper server configuration. You can't deploy to Vercel or Netlify like you would with a headless CMS. Budget $20-$100/month per site for decent managed hosting. Second, major version upgrades. Craft doesn't let you skip versions, so going from Craft 3 to 5 means stepping through 3 to 4, then 4 to 5, each with breaking changes to Twig templates and plugin compatibility. We've seen agencies spend 20-40 hours per upgrade. Third, developer dependency. Craft assumes your team has PHP developers on hand. If your agency is moving toward JavaScript stacks, maintaining Craft expertise becomes an overhead.
Should I migrate from Craft CMS to a headless CMS?
It depends on your stack direction. If your team is comfortable with PHP and Twig, and your sites are traditional server-rendered builds, Craft still works well. But if you're building with Next.js, React, or any modern JavaScript framework, Craft becomes friction. Its GraphQL API exists but it's a bolt-on, not a native experience. The content modelling in Craft is genuinely good, and that translates well to headless platforms. We've migrated Craft sites to Sanity where the content structures mapped over almost one-to-one. The frontend rebuild in Next.js typically takes 6-10 weeks, and the result is faster, cheaper to host, and easier to iterate on.
What's the biggest challenge when migrating off Craft CMS?
Twig templates. Every piece of frontend logic in a Craft project lives in Twig, and none of it carries over to a modern JavaScript framework. You're essentially rebuilding every template from scratch. Content migration itself is manageable since Craft's data structures are well-organised, and you can export through the Element API or direct database queries. The other challenge is plugin replacement. If you rely on Craft plugins for forms, SEO, or search, you need to find equivalents in your new stack. We build a dependency audit before any Craft migration so there are no surprises mid-project.
