Managing a website should be about your content and design, not managing build tools.

Ghost recently introduced a built-in Theme Editor in Ghost Admin, letting publishers edit theme files directly without uploading new theme archives for every change. It's a great step toward making theme customization more accessible.

However, most modern themes come with prebuilt CSS and JavaScript files. Theme developers write their code in multiple, readable source files, then run a build process that combines and minifies them into smaller files optimized for delivery to visitors. This keeps the codebase organized during development while keeping the final website fast.

This works fine in a typical development workflow, but the new Theme Editor has no build step of its own. If your theme depends on these prebuilt files, editing them directly in Ghost Admin means working with unreadable, minified code, with no way to regenerate the optimized versions afterward.

Smart Optimization removes this problem at the source.

Your files, optimized automatically

Smart Optimization is a new Synaps Media feature that automatically optimizes your HTML, CSS, JavaScript, and SVG files before they reach your visitors — no build step required on your end.

This means you can include plain, readable source files in your theme and edit them freely in Ghost's Theme Editor. Synaps Media handles the optimization transparently, in the background, on every request.

Smaller pages. Faster loads. No extra work.

Code Injection gets optimized too

Ghost's Code Injection is one of its most powerful features — a quick way to add custom styles or scripts without touching theme files. But those snippets are normally delivered exactly as you write them, comments and all.

With Smart Optimization, inline CSS and JavaScript from Code Injection is optimized as well, so your site stays lean even as you layer in customizations.

Available on all plans, at no extra cost

Smart Optimization is enabled by default for every Synaps Media website, across all plans. There's nothing to activate and nothing to pay — it just works.

If you ever need to adjust it, you can find the controls under Advanced Settings → Smart Optimization, where you can toggle optimization individually for HTML, CSS, JavaScript, and SVG.

Fast websites, by default

Smart Optimization is part of a broader commitment at Synaps Media: every site we host should be fast out of the box, without putting the technical burden on publishers. Performance shouldn't be a privilege reserved for those who know their way around a build pipeline. We'll continue building infrastructure-level improvements that work quietly behind the scenes, so you can stay focused on what matters — your content.
