CMS (content management system)
Software that lets someone who isn't a developer add and edit a website's content, such as pages, posts and portfolio items, without touching code.

What does CMS mean in practice?
A CMS separates content from layout. Staff write a post, add a project or change a banner in a form, and the site renders it in the agreed design. Options run from WordPress and Webflow to a small CMS built into a custom admin panel.
Content goes stale when every change needs a developer, which is the main argument for one. The trade-off is control: a fully open editor lets people break the layout, while a CMS over fixed sections keeps the design intact and limits what can change.
If you already run a CMS, connecting new tools to it usually means handing over access, so it is worth asking whether a tool can publish without holding your CMS keys.

Where has CMS come up in our builds?
The studio manages works, services, the blog and enquiries from its own superadmin panel. A work gets a URL slug from its title and an embedded YouTube or Vimeo video, and blog posts move through Draft, Scheduled, Published and Archived, with only published posts on the site.
The home page became a CMS over eight fixed sections, from a hero slider of one to eight slides to the featured blog, edited in place with character limits while the layout stays fixed.
AlwaysLoud never logs into a customer's CMS. Posts travel as signed JSON to a small receiver kit inside the customer's own backend, with WordPress and Webflow connectors for sites on those platforms.
Common questions about CMS
Should I use WordPress or a custom CMS?
WordPress suits content-led sites with standard pages. A small custom CMS inside your admin panel suits content tied to your own data, such as Flying Pup's works and enquiries, or pages whose layout must not be broken.
How do I let staff edit the home page without wrecking the design?
Make it a set of fixed sections with character limits rather than a free canvas. Proton's academy staff edit eight sections in place, and the layout can't change.
