Do you actually need a CMS?
Most sites don't need a content management system on day one. Here's how to tell if yours does.
A content management system exists to let people without engineering skills update a website. That's the whole job. Plenty of sites get one anyway, whether they need it or not, because it's the default assumption when someone says "build me a website."
The actual test
If your content rarely changes, hours, contact details, a services list, a handful of photos, you don't need a system for editing it. A hand-coded page updates just as easily with a short request to whoever built it, and you skip the ongoing cost of running and securing a CMS you barely touch.
You need one when someone on your team has to publish or update content regularly without waiting on a developer: a blog, a changing product catalog, seasonal offers, a growing library of case studies. At that point, editorial speed matters more than the small overhead of running a CMS, and it's worth the trade.
Coupled versus headless, briefly
A traditional CMS like WordPress bundles the editing interface and the public-facing site together. It's fast to set up and familiar to most editors, at the cost of tying your frontend to whatever that platform's themes and plugins allow.
A headless CMS separates the two: content lives in the backend, and the site that displays it can be built however you want, including as a fully custom, hand-coded frontend. It takes more setup, but it means adding a CMS doesn't force you into a templated look or a plugin-dependent stack.
How we approach it
Our default is to build the site itself hand-coded and framework-based, and only add a content layer once there's a real, ongoing editorial need for it. That keeps the site fast and free of plugin overhead for the parts that don't need to change often, while still giving your team a proper editing interface for the parts that do. It's a smaller, more deliberate footprint than installing a full CMS on day one because that's what every website "comes with."
