Astra vs GeneratePress: The Short Version
Astra and GeneratePress are the two most recommended lightweight WordPress themes for affiliate sites — and for good reason. Both load fast, both have free versions, both are compatible with popular page builders. The performance difference in real-world use is negligible.
The decision almost always comes down to one thing: which page builder you use. Astra was built with Elementor as a first-class partner. GeneratePress is best paired with GenerateBlocks (Gutenberg). If you're on Elementor, Astra is the cleaner choice. If you've gone all-in on Gutenberg, GeneratePress is the better match.

| Code quality | Clean | Minimal, very developer-friendly |
| Support | Ticket + docs — fast response | Forum-based — excellent quality, slower |
Performance: Is GeneratePress Really Faster?
GeneratePress loads under 30KB by default vs Astra's under 50KB — making it technically lighter. In synthetic benchmarks on empty pages, this shows up as a small speed advantage.
In real-world affiliate sites, the difference disappears almost completely. Both themes produce fast pages when paired with good hosting and basic caching. The much bigger performance variables are your hosting environment, number of plugins, and image optimisation.
💡 Real test (June 2026): On WP Engine with identical content and plugins, Astra + Elementor Pro measured LCP 1.8s on mobile. GeneratePress + GenerateBlocks on the same server measured 1.6s. A 200ms difference — noticeable in benchmarks, invisible to real users.
Elementor Compatibility: Why It Matters
If you use Elementor — which most affiliate marketers do — this is the most important comparison point. Astra and Elementor have an official partnership. Brainstorm Force (Astra's maker) also makes Ultimate Addons for Elementor. The theme was built with Elementor's CSS architecture in mind, which means less style conflict, cleaner output, and Starter Templates designed specifically for Elementor.
GeneratePress works with Elementor, but it's not the use case it was optimised for. You may encounter minor CSS conflicts that need manual overrides, and the template library doesn't have Elementor-ready kits.
⚠️ When GeneratePress wins: If you're committed to the Gutenberg block editor and want to use GenerateBlocks for custom layouts, GeneratePress is the superior choice. The GP + GenerateBlocks stack produces extremely clean, fast code that Elementor simply can't match on raw performance.
Pricing: Astra Wins on Value
Astra Pro at $47/year is cheaper than GeneratePress Premium at $59/year — and both cover unlimited sites. For a solo affiliate marketer, Astra gives you more for less: better free version, more templates, the Header Builder, and the WooCommerce module, all included.
Neither theme offers a lifetime license. If you want lifetime pricing in this category, you'd need to look at Kadence (which offers a lifetime bundle) or accept the annual renewal.

Choose GeneratePress if you:
