What Is Astra?
Astra is a WordPress theme built by Brainstorm Force, the same company behind the Spectra page builder and the Ultimate Addons for Elementor. It's the most popular free WordPress theme with over 1.8 million active installs and a reputation for being the go-to theme for affiliate marketers who use Elementor.
I've been using Astra across five of my affiliate sites for the past 18 months. What keeps me coming back is simple: it gets out of the way. Astra's default CSS is minimal, which means Elementor's output is clean and doesn't have to fight with the theme's styles. The result is faster pages and fewer layout headaches.
Bottom line upfront: Astra is my default theme for every new affiliate site I build. The free version is genuinely usable. Astra Pro at $47/year unlocks the Header/Footer Builder, which eliminates the need for a separate header plugin. If you're building on Elementor, there's no better-matched theme.
Performance: Real Speed Test Results
I ran GTmetrix tests on one of my affiliate review sites (WP Engine hosting, Sydney test server) with Astra + Elementor Pro. These are my actual results from June 2026:
For context: on the same WP Engine server with a different theme (GeneratePress), my LCP was 1.6s. Astra and GeneratePress are essentially tied on performance — the difference in real-world scores is negligible. What separates them is the Elementor compatibility and template library.
Performance tip: Enable "Optimized CSS Loading" in Astra's Performance settings to load only the CSS needed for the current page. Combined with WP Engine's caching, this shaved another 200ms off my TTFB in testing.
Key Features for Affiliate Sites
Advanced Header Builder (Pro)
The Header Builder in Astra Pro is a drag-and-drop interface for designing your site's header — logo placement, navigation menu, search bar, CTA button. You can set different headers for desktop vs mobile, create sticky headers that follow the user down the page, and add transparent headers for hero sections. For affiliate sites where the navigation CTA ("View Top Pick →") is a key conversion element, this control matters.
Starter Templates — Skip the Blank Page
Astra ships with 300+ Starter Templates in the free version — full-page designs you can import with one click and use as a starting point. For affiliate sites, there are review-style templates, comparison page layouts, and landing page designs. Importing a template, then customising it in Elementor, is how I built my last three affiliate sites in under 48 hours each.
WooCommerce Module
If you're linking to Amazon, promoting physical products, or running any kind of product-focused affiliate content, Astra Pro's WooCommerce module customises product pages, shop grids, and checkout layouts without additional plugins.
Spectra — Free Page Builder from the Same Company
Brainstorm Force also makes Spectra, a Gutenberg block plugin that adds advanced blocks (pricing tables, review stars, counters, sliders) to the native block editor. If you want a lighter setup than Elementor, the Astra + Spectra combo is an increasingly popular choice for performance-first affiliate sites.

Astra Pricing 2026
Astra is sold in tiers. For most solo affiliate marketers, either the free version or the Pro plan is the right choice. The bundles include Spectra Pro, Ultimate Addons for Elementor, and other Brainstorm Force tools.
- Full lightweight theme
- 300+ Starter Templates
- Elementor/Beaver/Gutenberg ready
- Basic Customiser options
- All Free features
- Advanced Header Builder
- Advanced Footer Builder
- Blog Layouts
- WooCommerce Module
- Priority support
- Astra Pro
- Spectra Pro
- Ultimate Addons for Elementor
- Starter Templates Pro
- All future products
My recommendation: Start with Astra Pro at $47/year — unlimited sites, Header Builder, all the features you need. Upgrade to the Essential Bundle later if you want Spectra Pro or Ultimate Addons for Elementor. The commission on Astra Pro is up to 50%, so it's worth mentioning to your readers if you're in the hosting/tools niche.
Astra vs GeneratePress vs Kadence
The three main lightweight WordPress themes compete closely on performance. Here's how they compare for affiliate use cases:
| Theme | Base Size | Free Version | Pro Price | Best For |
|---|---|---|---|---|
| Astra | <50KB | ✓ Excellent | $47/yr | Elementor users, affiliate sites |
| GeneratePress | <30KB | Limited | $59/yr | Performance-first, developer-friendly |
| Kadence | <60KB | ✓ Good | $79/yr | Block editor users, WooCommerce |
| OceanWP | ~100KB | Basic | $43/yr | WooCommerce stores |
GeneratePress is technically lighter but the free version is more restricted and the community is smaller. Kadence is an excellent alternative if you work primarily in the Gutenberg block editor. For affiliate marketers who use Elementor — which is the majority — Astra's purpose-built compatibility is the deciding factor.
