Overview

It adds 30+ professional blocks to the WordPress block editor including call-to-action sections, team members, testimonials, and counters. Spectra integrates tightly with Astra, sharing design tokens for typography and colours, which makes the Astra + Spectra combination a popular choice for agencies building professional WordPress sites natively within Gutenberg. Spectra is free with over 1 million active installs, with a Pro version adding advanced animations, custom icons, and additional blocks.

Why it matters for B2B
B2B teams already using the Astra theme benefit from Spectra's shared design token system — colours and typography defined in Astra automatically apply to Spectra blocks, ensuring visual consistency across all page elements without manually aligning styles. This reduces design maintenance overhead as the site grows and new pages are added.
