Why fastCMS is so fast
No speed plugin, no CDN, no tricks. It's how every page is built.
Static page cache
Your server hands visitors ready-made HTML, so most visits never run PHP or touch the database.
Small, plain pages
A fastCMS home page is about 24 KB of HTML, under 5 KB once compressed. No page builder, no plugin stack.
Images done properly
Every upload becomes WebP in four sizes and each browser picks the smallest that fits. Sizes are set in advance, so nothing jumps.
Fonts on your own server
Each theme carries its own fonts. No calls to Google Fonts or any other outside server before your page can show.
Scripts wait their turn
The little JavaScript a theme uses loads after the page is on screen, so nothing holds it back: 0 ms blocking time.
AI in the admin, not on your pages
Autopilot, Growth and the AI tools run in the admin. They add nothing to the pages your visitors load.
What speed does for you
Better rankings
Google uses page experience, including Core Web Vitals, when it ranks pages. fastCMS passes all three before you do anything.
Visitors who stay
People leave slow pages. Fast ones get read, clicked and shared, which is what a blog is for.
Cheap hosting is fine
Light pages need little from the server. fastCMS flies on ordinary shared hosting, with no CDN or speed plugin.
Fast from the first page
Install fastCMS on your own hosting in two minutes. Every article you publish is just as quick.
