Challenges with Prismic
Key pain points
We have a long history with Prismic, and at one point, we were agency partners, so count us as biased. However, if you're anything like us, we've had an absolutely terrible experience with Prismic.
They've historically changed their API ad hoc, resulting in many broken websites, which is especially bad for an agency. They've dumped infrastructure on the community, resulting in expensive migration bills and client dissatisfaction and they've updated their system with no way to migrate other than to rebuild your entire website for literally years.
If you're having a hell of a time, we can help you move away and do it without breakages. We've had to migrate quite a few folks and we have a standardised process that lets us migrate images, videos, text and content structure to the platform of your choice.
Dependency on third-party hosting
You don’t control the infrastructure, Prismic does. So you’re tied to their uptime, limits, and CDN behaviour.
Limited native integrations
Most serious integrations require extra tooling or custom code because Prismic’s built-in ecosystem is pretty thin.
Steep learning curve
Slices, custom types, and the editor workflow take time to understand, especially for teams new to component-driven CMS structures.
Lack of built-in versioning
There’s no full document history or global rollback, meaning mistakes are harder to recover from without workarounds.
Escalating pricing model
Costs jump fast as you add seats, locales, or repositories, making it expensive to scale a growing content team.
Limited out-of-box features
Beyond basic content creation, most advanced needs require custom development, external tools, or plugins.
Benefits of Kentico
Key advantages
If Corporate Memphis art, dashboards, and spreadsheets are what you need, Kentico might be your happy place. The interface feels like Microsoft Office; that is, it is familiar, editor-friendly, and hard to break. And unlike platforms that need 14 plugins and a prayer, Kentico ships with the whole toolkit. It has marketing automation, e-commerce, workflows, multisite, multilingual, and the entire lot.
It scales well, handles heavy enterprise workloads, and integrates cleanly through APIs. But it is not the right fit for tiny brochure sites, but for large organizations that want everything under one roof, it’s a serious contender. If you’re unsure whether you really need the full armoury, send it our way and we’ll tell you if you’re ready for Kentico or if you’re just buying a tank to deliver pizza.
User-friendly interface
Kentico’s UI feels familiar with “Office toolbar,” like functions, rather than “developer terminals.” Editors can publish, schedule, and update content without needing a developer on standby.
Built in tools
You don’t need to glue together 12 plugins just to run campaigns or sell products. Kentico ships with automation, personalization, analytics, and e-commerce baked in.
Flexible API and extensibility options
If your team speaks .NET, Kentico supports it. Its APIs and integration options make it easier to connect CRMs, ERPs, BI tools, and custom services without duct-tape engineering.
Workflow and role management system
It has multiple approvers, granular permissions, and strict publishing rules. Legal, marketing, and IT can all sign off without stepping on each other.
Fast onboarding + safe staging
Training is quick, publishing is simple, and staging environments keep mistakes from going live. Teams can work confidently without “oops, wrong button” moments.
Headless-ready
If you want speed, security, and headless flexibility, Kentico delivers. Content moves fast, scales well, and supports multi-site or multilingual setups without falling over.
Common questions
Prismic to Kentico migration FAQs
Answers to the most common questions about Prismic to Kentico migration
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.
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.
