The Architecture That Killed Useless JavaScript
The fundamental problem of the modern web in one sentence: sites load code nobody needs.
There are two types of websites in 2026. Assembled sites — WordPress with 23 plugins, a premium theme weighing 4 MB, a visual builder injecting 47 nested divs to display a button. And engineered sites — where every line of code exists for a reason, where speed is a property of the architecture, where intelligence isn't a plugin bolted on but the nervous system of the site.
Glorics builds the second type.
We don't sell "fast websites." We sell an agentic platform: a site that thinks, adapts, and speaks to machines in real time. Under the hood, it's a Headless SSR engine. On top, it's a control console. In between, it's a middleware that transforms every page into a node of semantic intelligence.
A WordPress site with WooCommerce, Yoast, a slider, and a chat widget loads 2 to 4 MB of JavaScript. The browser receives an empty HTML skeleton, downloads megabytes of scripts, executes them, and only then — only then — displays the content. That's Client-Side Rendering. And it's a disaster.
For the user, that means 3 to 5 seconds of waiting on mobile. For Google, a catastrophic LCP and Core Web Vitals scores deep in the red. For AI agents — GPTBot, PerplexityBot, ClaudeBot — it's worse: they don't load JavaScript. They receive the empty HTML skeleton. They see nothing. Your site is invisible to the machines that decide your visibility.
Our architecture solves this at the root with a radical principle: zero JavaScript by default.
Every page is pre-rendered server-side as pure HTML. The browser receives a complete page, immediately displayable, with nothing to execute. The content is there. The structured data is there. The metadata is there. LCP is dominated by network speed, not JavaScript parsing — because there's nothing to parse.
When a page needs interactivity — a contact form, a dynamic component, a chat — we use the Islands architecture. Only the interactive component loads its own JavaScript, and only when it's visible on screen. The rest of the page stays static HTML.
WordPress / React
The browser does all the work:
SSR + Islands Architecture
The server does the work once:
The result is measurable. A Glorics site delivers an LCP under 0.8 seconds on mobile. An INP under 50 milliseconds — four times better than Google's threshold. A CLS of zero. A PageSpeed score of 100.
These are not theoretical targets. These are the real numbers from our production sites.
Source: Google Search Central: "Understanding Core Web Vitals" (December 2025) — Google recommends LCP < 2.5s, INP < 200ms, CLS < 0.1. Glorics sites exceed these thresholds by a factor of 3 to 4.
