From HubSpot CMS to ButterCMS
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.
Key advantages
ButterCMS is one of those headless CMS platforms that genuinely nails the onboarding experience. We've seen content teams go from zero to confidently building pages and blog posts within a few hours, which is rare in the headless world. The dashboard is clean, the API explorer is thoughtfully designed, and the starter templates for popular frameworks mean developers aren't starting from scratch every time.
From an agency perspective, the standout quality is how little hand-holding editors need after launch. The interface is intuitive enough that marketers can create pages, manage blog content, and handle SEO metadata without constantly pinging the dev team. The built-in blog engine is a genuine differentiator. Most headless CMS platforms treat blogging as an afterthought, but ButterCMS was originally built around it, and it shows in the quality of the authoring experience.
The API performance is consistently fast, and the SDK support across languages like JavaScript, Python, Ruby, and PHP is solid. Their customer support team is also notably responsive and genuinely receptive to feature requests, which is something we don't often see from CMS vendors. For small-to-mid-sized projects where you need a reliable content API without overcomplicating things, ButterCMS delivers.
We'd particularly recommend it for teams that need a polished blog alongside structured page content, and who value simplicity over infinite extensibility. It's a CMS that knows what it is and does that thing well.

Exceptionally easy onboarding
Content teams can be productive within hours, not days. The dashboard is clean and the learning curve is one of the gentlest we've seen in headless CMS land.
Built-in blog engine
Unlike most headless platforms where you have to model blog content from scratch, ButterCMS ships with a purpose-built blog engine that includes categories, tags, authors, and SEO fields out of the box.

Fast and reliable content API
The read API is consistently quick with global CDN delivery. For content-heavy sites, the performance is solid and predictable.

No seat limits on any plan
Every plan includes unlimited users, which is genuinely unusual in this space. You won't get punished for growing your content team.

Responsive customer support
Their support team is quick to respond and genuinely open to feature requests. We've seen roadmap items added based on customer feedback, which builds real trust.

Strong SDK and framework coverage
Official SDKs for JavaScript, Python, Ruby, PHP, and more, plus starter projects for React, Next.js, Vue, Angular, and other frameworks that actually work out of the box.
