Challenges with HubSpot CMS
Key pain points
HubSpot CMS has its perks, but you practically need a Mr. Moneybags subscription to keep the lights on. Pricing shoots up the moment you add seats, automations, or anything remotely “enterprise,” and you can only hope the pricing team doesn’t wake up one day and charge the equivalent of a beach-facing villa.
It’s also not winning any awards for flexibility. Deep customization is limited, the theme system is rigid, and you’re stuck learning HubL, a proprietary template language that no one dreams about using. The plugin ecosystem is tiny compared to WordPress, so advanced requirements usually mean custom builds, workarounds, or giving up. And yes, parts of the system can feel slow and clunky when you least expect it.
If you’re okay with the trade-offs, great. If not, you know where to find us.
Expensive pricing structure
HubSpot gets pricey really fast with every new seat, feature, or automation. It ends up feeling like a fresh subscription to financial pain.
Limited customization flexibility
The theme system is rigid, and anything beyond surface-level edits usually needs a developer. “Drag-and-drop” has limits… and you’ll hit them quickly.
Smaller theme and plugin ecosystem
Compared to WordPress or open-source giants, HubSpot’s marketplace feels tiny with fewer prebuilt solutions and more custom work.
Proprietary HubL language
Say hello to HubL, HubSpot’s own templating language. It works… but only in HubSpot. Enjoy the vendor lock-in.
Platform lock-in
Once you're in, getting out feels like moving out of a house with 14 years of hoarded junk. Migration isn’t fun.
E-commerce limitations
HubSpot CMS can run landing pages and lead funnels, but full-scale eCommerce? Not its game and definitely not its strength.
Benefits of KeystoneJS
Key advantages
KeystoneJS is one of those tools that really clicks if your team thinks in code. It's a schema-driven, open-source headless CMS built on Node.js, and the developer experience is genuinely good. You define your content models in TypeScript, Keystone generates a GraphQL API and an admin UI for you, and you're off. There's very little magic or abstraction hiding what's happening under the hood, which we appreciate when building complex projects for clients.
The Prisma ORM integration is a real highlight. Automatic migration generation, type-safe database access, and support for PostgreSQL, MySQL, and SQLite mean you're not fighting your data layer. If you've ever had to wrangle a CMS into supporting a non-trivial relational content model, you'll understand why this matters. Keystone lets you express those relationships cleanly and query them with a proper GraphQL API.
The document field editor is also worth mentioning. It's one of the more thoughtful rich text implementations we've seen in a headless CMS. You can embed custom React components directly into the editor, which means content teams can work with your actual design system components rather than generic blocks. For teams that care about structured content, Keystone gives you real tools to enforce it.
Where Keystone really shines is in projects where the development team wants full ownership of the stack. There's no vendor lock-in, no proprietary query language, and no surprise pricing tiers. If you want a CMS that feels like a well-designed library rather than a platform, Keystone delivers on that promise.
Schema-as-code with full TypeScript support
Define your entire content model in TypeScript with strong type inference throughout. The schema drives everything from the database to the admin UI to the GraphQL API.
Automatic GraphQL API generation
Every content type you define automatically gets a full CRUD GraphQL API with filtering, pagination, and relationship resolution. No manual endpoint wiring needed.
Prisma-powered database layer
Built on Prisma ORM with automatic migration generation and type-safe queries. Supports PostgreSQL, MySQL, and SQLite out of the box.
Flexible document field editor
The rich text editor supports custom embedded components that map to your design system, giving content editors structured authoring without sacrificing flexibility.
Granular access control
Fine-grained, field-level access control defined in code. You can write custom logic for create, read, update, and delete operations per field or per list.
Fully open source with no vendor lock-in
MIT licensed with no paid tiers or proprietary features gated behind a subscription. You own the entire stack and can host it wherever you want.
Common questions
HubSpot CMS to KeystoneJS migration FAQs
Answers to the most common questions about HubSpot CMS to KeystoneJS migration
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.
What makes migrating from KeystoneJS difficult?
KeystoneJS stores data through Prisma, so the database layer is well-structured and easy to export. The harder part is replacing everything Keystone doesn't give you. Most Keystone projects have custom-built preview systems, publishing workflows, and access control logic that are tightly coupled to the Node.js backend. Rebuilding those features in a new CMS takes planning. We typically budget 4 to 8 weeks for a Keystone migration depending on how much custom infrastructure the team has built around it.
Why do teams move away from KeystoneJS?
Deployment complexity is the number one reason. Teams love Keystone during local development, then hit a wall getting it reliably into production. The Docker images can balloon past a gigabyte, the docs don't cover production hosting well, and there's no managed hosting option. The small community compounds this problem. When you hit an edge case, there are fewer people who've solved it before. Content editors also struggle with the admin UI, which lacks visual editing, live preview, and built-in publishing workflows that competing platforms ship by default.
How do we extract our content from KeystoneJS?
Since Keystone uses Prisma ORM, your content lives in standard PostgreSQL, MySQL, or SQLite tables with clean schemas. You can export directly from the database using SQL dumps or Prisma's query API. The content model is defined in your TypeScript codebase, so mapping fields to a new CMS is straightforward. We write automated scripts that handle the data transformation, including resolving relationships between lists and migrating file references. For a project with 20 to 50 Keystone lists, extraction and transformation usually takes 1 to 2 weeks.
