Overview

Astra is one of the most popular lightweight WordPress themes, with over 2 million active installations. It is designed to be fast out of the box — under 50KB page size with no jQuery dependency on the front end. Astra pairs natively with all major page builders (Elementor, Bricks, Breakdance, Beaver Builder) and Gutenberg, providing the theme framework while the builder handles content layouts. Its Starter Templates library includes 250+ pre-built website designs for different industries, many B2B-relevant. Astra Pro at $49/year unlocks advanced header and footer customisation, custom layouts, and WooCommerce enhancements.

Key features

  • Under 50KB page size u2014 one of the lightest WordPress themes available
  • No jQuery dependency on the front end for faster load
  • 250+ industry-specific starter templates including many B2B
  • Native compatibility with Elementor, Bricks, Beaver Builder, and Gutenberg
  • Advanced header/footer builder (Pro)
  • Custom layouts for single posts, archives, and WooCommerce (Pro)

Common use cases

  • B2B team picking a lightweight theme foundation before installing a page builder
  • Agency starting a new client site from one of 250+ industry starter templates
  • Performance-focused developer wanting a zero-jQuery base theme

Why it matters for B2B

The theme is the performance foundation of every WordPress site. Astra's under-50KB page size and zero jQuery dependency mean pages load faster before any caching plugin or CDN is applied. For B2B teams pairing Astra with Elementor, Bricks, or Beaver Builder, the theme's minimal weight ensures the builder's features add performance overhead on top of a fast baseline rather than a slow one.

Pros

  • Fastest standard WordPress theme at under 50KB with no jQuery
  • Most widely tested for compatibility with all major page builders
  • Extensive free starter template library reduces design time

Limitations

  • Advanced header/footer and custom layout options require Pro plan
  • Some starter templates require Astra Pro to unlock fully
  • Less design uniqueness compared to premium paid themes
