Eight reasons to reboot your site

Full block theme (FSE)

Site-Editor native. No page builder, no build step. Edit everything from WordPress.

01

Cinematic POST boot

An optional power-on sequence with a POST log and progress bar. Skippable, honors reduced-motion.

02

⌘K command palette

Search and navigate like an IDE. A palette your visitors will actually use.

03

Live instrument blocks

Meters, oscilloscopes, status boards and terminals. Server-rendered, no build step.

+ BIOS X Core 04

5 variations · WCAG 2.2 AA

Amber, IBM Blue, Green Phosphor, Ivory and AAA. Every one passes AA, light and dark.

05

Devlog toolkit

Animated timelines and a draggable before/after slider. Tools writers love.

06

WooCommerce-ready store

WooCommerce styling ready to sell. The demo store content ships with BIOS X Core.

+ BIOS X Core 07

Works without JavaScript

Plugin-optional, 0 build, RTL and translatable. Still works with JS switched off.

08

+ BIOS X Core Live instrument blocks and the content types (projects, team, testimonials) are added by BIOS X Core, the free optional companion plugin. The theme works perfectly without it — plugin-dependent patterns simply do not appear.

Watch it boot

A real screen recording: the POST sequence, the parallax hero, the store, the A/B compare and the ⌘K palette.
