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 Prismic
Key advantages
Prismic is phenomenal for simplistic page-builder-style websites. Its simplistic drag-and-drop page builder, along with the newer code-based version, helps you generate like-for-like components and automates the developers' process.
The built-in media optimisation tool is also great, so you can ensure that even if you're uploading 4mb images, they're going to be scaled down with minimal compression artefacts.
Content scheduling capabilities
Prismic makes it ridiculously easy to plan content ahead with built-in scheduling without any plugins or workarounds. Just pick a time, hit schedule, and your release goes live exactly when you want it.
Intuitive visual editor
The editor feels natural even for non-technical teams, with clean previews and simple fields. It keeps the writing flow distraction-free while still giving developers structure.
Efficient slices feature
Slices let you build repeatable, flexible components that marketers can rearrange without breaking layouts. It’s the closest thing to structured Lego-blocks for content teams.
Rich media embedding
Embedding images, videos, and rich assets takes seconds. You don't need to hack templates. Just paste, pick, and publish.
Flexible component reuse
Developers create once, marketing teams reuse forever. Slices and custom types make content scalable without adding complexity.
Seamless publishing experience
Publishing is fast, predictable, and drama-free. If you want to do a small tweak or a full-page release, everything ships smoothly with minimal cognitive load.
Common questions
Kentico to Prismic migration FAQs
Answers to the most common questions about Kentico to Prismic 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 Prismic cost?
Prismic has a free plan for 1 user with limited API calls. The Starter plan is $7/month per user for small teams. The Small plan is $150/month for up to 25 users with more locales and API bandwidth. Medium is $500/month. Large and Enterprise plans go higher. The pricing jumps are significant once you need multiple locales or repositories. We've had clients hit the ceiling on the Small plan faster than expected because of how Prismic counts API calls and custom types.
What are the best Prismic alternatives?
Sanity is the alternative we recommend most. It gives you better content modelling, real-time collaboration, and a query language (GROQ) that's far more flexible than Prismic's API. Contentful is another option with a bigger ecosystem, though pricing is steeper. If you liked Prismic's Slices concept, Sanity's block-based content approach works similarly but with more depth. We've migrated multiple former Prismic agency partners to Sanity, and the developer experience improvement is always the first thing they mention.
Can I migrate from Prismic to another CMS?
Yes. We've migrated quite a few Prismic projects, mostly to Sanity. We export your custom types, documents, and media through Prismic's API, then restructure everything for the target platform. Prismic's Slice-based content maps well to Sanity's portable text and block system. Typical migrations take 3-5 weeks. We keep your existing Prismic site live throughout, so there's no downtime. The biggest challenge is usually handling Prismic's media library, since images need to be moved to a new CDN.
Is Prismic a good CMS for developers?
It's decent for simple projects. The Slice Machine tooling is clever and the TypeScript support has improved. But Prismic's API has limitations that frustrate developers on bigger projects. You can't do complex queries, filtering is basic, and the content modelling is shallow compared to Sanity or Contentful. The bigger issue is Prismic's track record of breaking API changes and infrastructure shifts that have caused production outages. Developers who need reliability and deep customization are better served elsewhere.
Why are teams leaving Prismic?
The main reasons we hear are API instability, limited content modelling depth, and pricing that doesn't match the feature set. Prismic has a history of making breaking changes to their API and infrastructure without adequate migration paths. One major version change left agencies (including us, when we were partners) with broken client sites and expensive rebuild bills. Teams also outgrow the content modelling quickly. Once you need complex relationships between content types, Prismic's flat structure becomes a bottleneck.
