From Builder.io to HubSpot CMS

We are the Builder.io to HubSpot CMS migration experts

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 Developers on forums describe spending days trying to get basic integrations working because the docs are outdated or incomplete.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Outdated and incomplete documentation

Developers consistently report that the docs are confusing, outdated, or missing critical steps.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 HubSpot CMS

Key advantages

HubSpot whole ecosystem is designed so business users can update pages, run campaigns, and push content without ever Slacking a developer at 9 p.m.

It’s genuinely simple to implement, the drag-and-drop editor behaves, and the CRM integration does all the heavy lifting, from personalization to lead capture to automated follow-ups. You barely need a dev unless you’re trying to make something unusually fancy, because HubSpot’s whole pitch is: “Let marketing ship it themselves.”

But if you do want to build something more complex or need help figuring out where HubSpot fits into your stack, reach out. We can help you avoid unnecessary and very expensive upgrades, weird theme restrictions, and the classic “why is this locked behind Enterprise?” surprise.

Intuitive drag-and-drop interface

Non-technical teams can update pages, layouts, and content without ever pinging a developer. The editor is straightforward, visual, and fast, making day-to-day site changes painless.

Deep CRM integration

Forms, leads, emails, CTAs, and all of it connect back to HubSpot’s CRM automatically. This gives teams real personalisation power and a unified view of how users move from visitor to lead to customer.

Built-in SEO tools and analytics

HubSpot flags issues, suggests improvements, and provides performance insights without extra tools. It’s practical for teams who want clear SEO direction baked directly into the CMS.

Secure cloud hosting with SSL/CDN

Hosting, security patches, SSL, and updates are all handled by HubSpot. Sites stay fast and secure without anyone babysitting servers or worrying about downtime.

Lead tracking and management

Every form submission, chat, and CTA is automatically tracked. Marketing and sales teams get full visibility into user behaviour without setting up a separate tracking stack.

Live WYSIWYG previews

Changes can be reviewed in real time before publishing, which reduces mistakes and makes approvals easier. What you see in the editor actually matches what goes live
