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 Developers on forums describe spending days trying to get basic integrations working because the docs are outdated or incomplete.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Outdated and incomplete documentation
Developers consistently report that the docs are confusing, outdated, or missing critical steps.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
Common questions
Builder.io to HubSpot CMS migration FAQs
Answers to the most common questions about Builder.io to HubSpot CMS migration
Can you migrate from Builder.io without losing your page designs?
Yes, but it takes work. Builder.io's visual editor stores page compositions as JSON that references your registered components. Those component registrations are tightly coupled to Builder's SDK, so you can't just export and import elsewhere. What you can preserve is the design itself. We extract the page structures, map them to equivalent components in the new system, and rebuild the composition layer. The visual output stays the same. Typical timeline is 6-10 weeks depending on how many page types and custom components are involved. The biggest time sink is usually recreating A/B test variants and personalisation rules that lived inside Builder's platform.
What does Builder.io actually cost?
Builder.io's free tier gives you 1 user and basic features, which is enough to evaluate but not to run a real project. The Growth plan starts at $49/month and includes more seats and content types. Beyond that, pricing gets opaque. Teams needing roles, scheduling, and higher API limits are pushed toward custom Enterprise plans that typically start in the $500-$1,000/month range. We've heard from freelancers and small agencies who were caught off guard by charges after exceeding limits on the Growth plan. Builder.io also charges per "impression" on higher tiers, which means your costs scale with traffic in ways that aren't always predictable.
How does Builder.io compare to a traditional headless CMS?
Builder.io is a visual page builder first and a CMS second. That distinction matters. If your primary goal is letting marketing teams build landing pages without developer involvement, Builder.io does that well. If you need structured content modelling, editorial workflows, multi-language support, or content that powers more than just web pages, a traditional headless CMS is a better fit. Builder.io's SDK embeds deeply into your frontend code, which creates vendor lock-in that most headless CMS platforms avoid. We typically recommend Builder.io only when the use case is narrow: high-volume landing page creation for marketing teams. For everything else, a headless CMS with a proper content model gives you more flexibility long-term.
What's the main risk of building on Builder.io?
Vendor lock-in. Builder.io's SDKs are woven into your component rendering layer, which means migrating away requires rebuilding how your pages are composed and rendered. That's not a content migration, it's an architecture migration. With a typical headless CMS, your content is accessible through standard APIs and your frontend is independent. With Builder.io, the two are intertwined. We've worked with teams who spent months extracting themselves from Builder.io because every page template needed to be recreated outside the platform. If you're evaluating Builder.io, go in with eyes open about the exit cost.
How much does HubSpot CMS actually cost?
HubSpot CMS starts at $25/month for the Starter tier, but that's a teaser price. Most teams end up on Professional ($400/month) or Enterprise ($1,200/month) once they need features like custom reporting, smart content, or additional contact tiers. The real cost shock comes from the CRM side. HubSpot bundles CMS with its marketing hub, and adding seats or automation workflows pushes the bill up fast. We've seen mid-sized companies paying $30,000-$60,000 per year once everything is bundled. That's a lot of money for a platform that still makes you write HubL templates.
Can you move a HubSpot site to a headless CMS setup?
Yes, and we've done it multiple times. The migration typically takes 6-10 weeks depending on how many pages, forms, and CRM integrations are involved. The trickiest parts are replicating HubSpot's form-to-CRM pipeline (which most teams replace with a dedicated form handler plus CRM API integration) and extracting blog content from HubSpot's proprietary format. Design preservation is straightforward if you're rebuilding in a modern framework. We usually rebuild the frontend in Next.js with a headless CMS for content, which gives you better performance and full design control without HubL's limitations.
Will I lose my HubSpot CRM data if I migrate the CMS?
No. HubSpot's CRM is a separate product from the CMS, and you can keep using it even if you move your website elsewhere. We typically set up the new site to push form submissions directly into HubSpot CRM via their API, so your sales team's workflows stay intact. The only thing you lose is HubSpot's native smart content features (content that changes based on CRM data), but those can be rebuilt with a personalisation layer or server-side logic. Most teams find the trade-off worthwhile because the CMS limitations were holding them back more than smart content was helping.
What are the main reasons companies leave HubSpot CMS?
The top three reasons we hear from clients are design limitations, HubL frustration, and pricing escalation. HubSpot's theme system restricts what you can build visually, and the moment you need something custom, you're writing HubL, a templating language that only works inside HubSpot. Developers hate it because it's a dead-end skill. Then there's cost. Teams start on a reasonable plan, add features over 18 months, and suddenly they're paying enterprise prices for what is still a fairly rigid website builder. Moving to a headless CMS removes all three problems at once.
