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 Contentful
Key advantages
Contentful is one of the most established headless CMS choices, and we still see plenty of customers land on it after a shortlist.
It's built around structured content, so you model fields once and pull them into any front end you like. That means no copy-pasted components scattered across pages. It also has first-party support for A/B testing and personalization through its Studio add-on, which most competitors don't match natively. The app ecosystem covers SEO, translation, validation, and asset management, and editors get live side-by-side preview for content they're working on.
If your team has the budget and the developer resources to model content properly, it's a solid pick.
API-first design
Contentful was built for APIs from day one, which means your content plugs cleanly into apps, websites, and mobile.
Developer-friendly flexibility
Schemas, content models, and references can be tuned however you like. If your stack is anything beyond “cookie-cutter,” Contentful won’t get in your way.
User-friendly interface
Editors enjoy using it. Clean UI, quick search, structured fields, and no “where does this go again?” confusion.
Extensive integration capabilities
Plug in analytics, eCommerce, automation, and translation. Contentful plays nicely with almost anything. And if something isn’t supported yet, you can wire it up yourself without hacking the platform apart.
Scales under traffic
Contentful's global CDN holds up under heavy load. We've run it on sites pushing millions of monthly requests without needing bespoke infrastructure to handle spikes.
Cloud-based architecture
You don't have to install, patch, or maintain anything. It’s fast, globally distributed, and always up to date. Your content team can ship from anywhere without a DevOps babysitter.
Common questions
Kentico to Contentful migration FAQs
Answers to the most common questions about Kentico to Contentful 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 Contentful cost?
Contentful has a Free tier with 10 users, 100K API calls per month, 25 content types, and 10,000 records. The Lite plan is $300/month for 20 users, 1M API calls, and 100GB CDN bandwidth. Premium is custom pricing with unlimited API calls and a 99.99% uptime SLA. We've seen teams hit the free tier's API ceiling or content type cap fast, and the jump to Lite is often forced by a single limit rather than a feature need.
What are some alternatives to Contentful?
Sanity is the alternative we recommend most. It gives you real-time collaboration, a customizable studio, and pay-as-you-go pricing that doesn't punish you for scaling. Storyblok is worth considering if your editors want a visual builder. We've migrated teams off Contentful to both, and Sanity consistently gets the best feedback from developers and content editors alike.
How does Contentful compare to Sanity on pricing?
Contentful charges $300/month for its Lite plan with hard caps on API calls, seats, and content types. Sanity's pricing is usage-based, starting free and scaling with actual consumption. For most mid-size projects, Sanity ends up significantly cheaper. The real difference is that Sanity doesn't gate core features behind premium tiers the way Contentful does with roles, SSO, and content modelling limits.
Can I migrate from Contentful to Sanity?
Yes. We've migrated dozens of Contentful projects to Sanity. The structured content model in Contentful maps well to Sanity's schema, so most migrations are straightforward. Content, assets, references, and localized fields all transfer. Our typical migration takes 2-4 weeks depending on the number of content types and the complexity of your references. We handle frontend rewiring too if you're on Next.js or a similar framework.
Is Contentful good for large enterprise websites?
It can be, but the costs get steep. Enterprise plans are custom-priced and often land in the $50,000-$100,000+ per year range. If you have deep pockets and your team already knows the platform, it works. If you're evaluating from scratch, we'd push you toward Sanity for enterprise use. You get equivalent API performance, better real-time editing, and a pricing model that doesn't penalize growth.
