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 Sanity
Key advantages
You know where our bias' lies. We think Sanity is literally the best headless content management out there. The schema is code-based, so it can be easily versioned, scaled, and extended without a heap of third-party hoops to jump. Providing you build it with a solid foundation, which we always recommend Turbo Start Sanity, it's going to be the most valuable hub for content you can imagine.
It's got a very unique tooling called the Live Content API, which in simple terms means
when you press publish, its live.
No issues with caching, and a single API usage that scales perfectly with multichannel content delivery.
It also offers one of the best editorial experiences in the industry with Presentation and customizable content structures. We're obviously huge fans of it, and we've pivoted our business with it when we realised how ahead it is.
Real time collaboration
You write, your teammate tags in, adds citations, and updates the same doc without stepping on each other. It’s the fastest way to ship content without the “who has edit access?” chaos.
Live preview block building
With Sanity, you don’t have to guess what your page might look like. Real-time previews update the moment you type. It’s a 1:1 mirror of your site before it ever goes live, so your campaigns look right the first time.
Meta tags, structured content
Sanity’s structured content gives Google clean data and rich schema, so your pages surface higher without manual hacking. Automated schema, smarter metadata, and better rankings.
Better media management
A blazing-fast media library with first-class support for Cloudinary, Mux, Wistia and more. Upload, drag-and-drop, preview without wrestling with assets, and waiting for spins of doom.
Automated social sharing
Ever wanted to share one update, and automatically populate every social platform? Welcome to the future we've built that. Why should social media be a chore.
Automated image generation
Sanity keeps your subject centred and sharp like a tiny author thumbnail or a full-page hero banner. There are no awkward crops, or chopped heads. Your visuals just look right everywhere.
Common questions
Kentico to Sanity migration FAQs
Answers to the most common questions about Kentico to Sanity 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.
Why should we migrate to Sanity instead of another headless CMS?
Sanity's Live Content API means content goes live the instant you press publish, with zero caching issues. We've migrated teams from WordPress, Contentful, Drupal, and legacy platforms, and the consistent feedback is that the editorial experience is faster and more flexible. The schema-as-code approach means your content model is version-controlled alongside your codebase. Pricing starts free for small teams and scales predictably, unlike platforms that hit you with surprise API overage bills.
What does a migration to Sanity actually involve?
A typical migration has three phases. First, we map your existing content model to a Sanity schema, which usually takes 1 to 2 weeks depending on complexity. Second, we build automated migration scripts that transfer your content, media assets, and relationships. Third, we set up the frontend integration and editorial workflows. For a mid-sized site with 500 to 2,000 pages, the full process usually runs 4 to 8 weeks. We use our Turbo Start Sanity foundation to accelerate the setup so you're not starting from zero.
How long does it take before our content team is productive in Sanity?
Most editors are comfortable within the first week. Sanity's Presentation tool gives them a side-by-side live preview that feels intuitive, especially for teams used to visual page builders. The real-time collaboration means multiple editors can work on the same document without conflicts. We typically run a 2-hour onboarding session and provide a custom guide tailored to your specific content model. After that, editors rarely need developer support for day-to-day publishing.
How much does Sanity cost?
Sanity's Free plan includes 20 user seats, 10,000 documents, 1M CDN API requests, 250K regular API requests, 100GB of assets, and unlimited locales. The Growth plan is $15 per seat/month with 25,000 documents and the same API allowances, plus pay-as-you-go overages and 5 roles including Editor, Developer, and Contributor. Enterprise pricing is custom for organisations that need custom roles, SLAs, or private datasets. Most mid-size teams we work with stay well inside Growth's limits.
