Spectra
Spectra is a WordPress plugin by Brainstorm Force, the company behind the Astra theme, that adds a library of blocks and ready-made templates to the WordPress block editor, formerly known as Ultimate Addons for Gutenberg. It provides blocks such as containers, forms, sliders, tabs, testimonials and pricing tables, plus responsive controls for building full pages without a separate page builder. The core plugin is free, and Spectra Pro is a paid upgrade. Sites using Spectra are block-editor WordPress sites, a fit for WordPress agencies, block and template vendors and hosting providers.
Spectra is active on 144,508 WordPress websites, which is 0.3% of all WordPress plugins detections we record. Websites running Spectra are most often served from United States (42,394), Germany (21,095) and France (12,465), and .com, .de and .fr are the most common domain endings. The most common versions are 2.20.5 (62,612 sites) and 2.19.26 (9,963).
