From Builder.io to Kentico

Challenges with Builder.io

Key pain points

Builder.io looks impressive in demos but the reality of day-to-day usage tells a different story. The editor can be laggy, especially with more than 30 components on a page, and we have seen reports of outright crashes that lose unsaved work. The documentation is a persistent sore point. Developers on forums describe spending days trying to get basic integrations working because the docs are outdated or incomplete. For an agency setting up projects for clients, unreliable documentation means unpredictable timelines.

Pricing is another area where Builder.io catches teams off guard. The free tier exists but is quite limited, and costs ramp up quickly once you need features like roles, scheduling, or higher usage limits. We have seen complaints from freelancers and small teams about unexpected charges and slow support response times when trying to resolve billing issues. The lack of self-hosting is also a hard blocker for some clients with strict data residency requirements.

The biggest concern from our perspective is vendor lock-in. Builder.io's SDKs are deeply embedded in your frontend code, and if you ever need to migrate away, you are essentially rebuilding your page composition layer from scratch. There is also no real-time collaboration, so two editors working on the same page can overwrite each other's changes without warning.

Editor performance and stability

The visual editor becomes laggy with complex pages and has been reported to crash, losing unsaved work. Teams with content-heavy pages will feel this friction daily.

Outdated and incomplete documentation

Developers consistently report that the docs are confusing, outdated, or missing critical steps. Getting started takes far longer than it should for a tool that sells itself on speed.

Vendor lock-in risk

Builder.io's SDKs are tightly coupled to your frontend. Migrating away means rebuilding your entire page building and composition layer from scratch.

Limited collaboration tools

Builder.io now offers branching and peer review workflows in its Fusion product, but true real-time co-editing is still missing. Editors working outside of the Projects workflow can still overwrite each other's changes.

Pricing escalation

Costs ramp up quickly beyond the free tier, and teams report unexpected charges. Basic features like roles and scheduling sit behind higher-priced plans.

Slow and unresponsive support

Multiple users report delayed support responses, unresolved tickets, and difficulty getting refunds or cancellations processed in a reasonable timeframe.

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.

Powerful built-in marketing automation, e-commerce, and customization tools

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.
