Why teams leave Kentico

The Kentico problems a move to Sanity solves

If these sound familiar, your site has outgrown Kentico. Here is what changes after the migration.

Licensing, hosting and upgrade costs

Licences, Windows hosting and version upgrades add up, even for a marketing site.

Sanity is fully hosted. There are no plugins or servers to patch.

Heavy server-side rendering

Widgets, macros and server rendering slow pages down and make caching tricky.

Next.js pages are pre-built and served from a global CDN.

Patching and hotfixes

Hotfixes and major upgrades are projects of their own, and they often get postponed.

No CMS server runs on your domain; the live site is static.

Content locked into page types

Page types and widgets tie content to current templates, so reusing it elsewhere takes custom work.

Structured content that feeds your site, apps, emails and AI search.

A shrinking pool of specialists

Few developers know Kentico well, so even small changes depend on specialist time.

A Sanity Studio built around your team, with live visual preview.

Hard to add new channels

Feeding an app, a second site or a new language means more custom .NET code.

One content source for any number of front ends and locales.
Kentico to Sanity

Is Kentico holding your site back?

Licences, upgrade projects and specialist-only changes cost your team time and your site revenue every month. We move it to Sanity in 4–8 weeks, keeping your URLs, content and rankings intact.

  • Free audit and fixed-scope quote in 5 working days
  • Every URL mapped, redirected and crawl-tested
  • No planned downtime at cutover
