HubSpot CMS to Headless Migration
Your HubSpot CMS Burns $4,320 A Year While Your Pages Score 50
Why leave HubSpot CMS?
- Paying $360–1,200/month for CMS features your team barely uses
- Watching your Lighthouse score stall at 50–70 because of platform JavaScript overhead
- Locked into HubL templating language with zero portability to other platforms
- Storing your content inside HubSpot's walled garden with no clean export path
- Adding $45/month per seat every time your editorial team grows
- Hitting content architecture limits that modern headless CMSs solved years ago
What you gain
- Every page scoring Lighthouse 95–100 with sub-second load times
- Hosting costs falling to $0–50/month while performance doubles
- Your content living in Sanity or Supabase — portable, version-controlled, yours
- HubSpot CRM, forms, tracking, and automation fully preserved and wired in
- Your frontend rebuilt in TypeScript with complete design and logic control
- Saving $3,720–4,320 per year on platform fees alone, compounding annually
The HubSpot CMS tax
HubSpot CMS Hub starts at $360/month (Professional) and goes to $1,200/month (Enterprise). For that price you get a CMS that scores 50-70 on Lighthouse, locks your content inside the HubSpot ecosystem, and requires HubL — HubSpot's proprietary templating language — for any customisation.
When teams outgrow HubSpot CMS
HubSpot CRM is excellent. HubSpot CMS is not. The confusion comes from bundling — teams adopt HubSpot CRM and then use CMS Hub because it is in the same platform. But HubSpot CMS has real limitations: poor Core Web Vitals, HubL vendor lock-in, expensive per-seat pricing, and inflexible content architecture.
The headless path: keep HubSpot CRM, replace HubSpot CMS
The smartest migration keeps HubSpot CRM intact (it is genuinely good at what it does) and replaces only the CMS layer. Content moves to Sanity or Supabase. The frontend is rebuilt in Next.js or Astro. HubSpot forms and tracking scripts are preserved for marketing continuity.

Common questions
Can I keep HubSpot CRM but replace HubSpot CMS?
Yes — this is the recommended approach. HubSpot CRM continues managing contacts, deals, and marketing automation. Only the website CMS is replaced with a headless architecture. HubSpot tracking scripts and forms embed into the new frontend seamlessly.
What is wrong with HubSpot CMS performance?
HubSpot CMS loads the HubSpot platform JavaScript on every page, uses server-side HubL rendering, and includes tracking scripts that add 100-200KB. Lighthouse scores of 50-70 are typical. This cannot be optimised within the platform — it is architectural.
What is HubL and why is it a problem?
HubL is HubSpot's proprietary templating language. It is only useful inside HubSpot CMS. Any templates or customisations you build in HubL are not portable — they cannot be used anywhere else. This is vendor lock-in at the code level.
How much will I save?
HubSpot CMS Professional costs $360/month ($4,320/year). A headless site on Vercel + Sanity or Supabase costs $0-50/month. The annual savings of $3,720-4,320 typically covers the migration cost within the first year.
Will my HubSpot forms and tracking still work?
Yes. HubSpot forms embed via JavaScript on any website. HubSpot tracking code embeds the same way. All lead capture and analytics continue working exactly as before — you are only changing the CMS layer, not the marketing platform.
How long does the migration take?
A standard HubSpot CMS site (20-50 pages, blog, landing pages) takes 4-6 weeks. The migration includes content export, CMS setup (Sanity or Supabase), frontend rebuild, and HubSpot form/tracking integration.
Can HubSpot be used as a CMS?
Yes, HubSpot can be used as a CMS. It offers a comprehensive suite of tools for building, managing, and optimizing websites. HubSpot's CMS Hub provides features such as drag-and-drop page editing, built-in SEO recommendations, and adaptive testing. It also integrates seamlessly with its CRM and marketing tools, allowing for a cohesive workflow. As a traditional CMS, HubSpot is ideal for those looking to manage content and lead generation in one platform. However, for headless architecture, developers may consider other options that better support decoupled content delivery.
What is the difference between HubSpot CRM and CMS?
HubSpot CRM and CMS serve different functions within the HubSpot ecosystem. HubSpot CRM is designed to help businesses manage customer relationships by organizing, tracking, and nurturing leads and customer interactions. It focuses on sales automation, contact management, and pipeline tracking. On the other hand, HubSpot CMS is a content management system used for building and managing websites. It allows users to create, edit, and optimize web content while integrating seamlessly with HubSpot's marketing tools. Essentially, the CRM is about customer data, while the CMS is about web content.
