GeneratePress vs Kadence vs Astra: Theme Comparison
A developer's comparison of the three most popular lightweight WordPress themes. Performance data, builder compatibility, pricing, and when to use each one.
Short answer: GeneratePress for raw speed and developer control. Kadence for the best balance of builder features and performance. Astra for the largest template library and broadest compatibility. All three are excellent — the "wrong" choice among these three is still better than 95% of WordPress themes.
These three themes dominate the lightweight WordPress theme space for good reason. Each loads under 50KB, supports the block editor, and works with every major page builder. I have used GeneratePress on performance-critical projects and Elementor Pro on sites where clients need visual editing. The theme underneath matters more than most people think.

GeneratePress — The Speed King
Why I choose GeneratePress when performance is non-negotiable.
GeneratePress loads under 10KB of CSS and zero JavaScript on a clean install. That is not a typo — it is the lightest WordPress theme available. No jQuery, no render-blocking resources, no bloat.
Where GeneratePress wins:
Raw performance. On identical hosting with identical content, GeneratePress consistently scores 5-15 points higher on Lighthouse than Kadence or Astra. For WooCommerce stores where page speed directly affects conversion rate, that difference translates to real revenue.
Developer control. GeneratePress has the most comprehensive hook and filter system of any WordPress theme. Over 100 hooks let you modify virtually any part of the theme without editing template files. This means cleaner customizations that survive theme updates.
GenerateBlocks. The companion block plugin adds layout, headline, button, image, and query loop blocks with full styling controls — without the weight of a full page builder. For developers comfortable with the block editor, GeneratePress + GenerateBlocks is the fastest design workflow available.
Stability. Tom Usborne (the solo developer behind GeneratePress) ships infrequent, deliberate updates. The theme does not break between versions. I have never had a GeneratePress update cause an issue on a client site.
Where GeneratePress falls short:
Template library is small. ~30 starter templates compared to Kadence's 100+ and Astra's 250+. If you need a ready-made design to start from, the options are limited.
Premium features require the paid version. The free version is functional but basic. The header builder, WooCommerce features, and most customization options require GP Premium ($59/yr or $249 lifetime).
Less intuitive for non-developers. The Customizer controls are powerful but assume technical comfort. Clients who need to make design changes themselves may find Kadence or Astra more approachable.
Pricing:
- Free version: Functional, basic customization
- GP Premium: $59/yr (1 site) or $249 one-time (unlimited sites, lifetime updates)
The $249 lifetime license is one of the best values in the WordPress ecosystem. Pay once, use on every project forever.
Kadence — The Best Balance
Why Kadence is increasingly my default recommendation for new projects.
Kadence hits the sweet spot between GeneratePress's performance focus and Astra's feature richness. It loads under 30KB, includes a header/footer builder in the free version, has excellent WooCommerce integration, and Kadence Blocks is the most full-featured free block plugin available.
Where Kadence wins:
Free tier is genuinely powerful. The free version of Kadence includes features that GeneratePress and Astra lock behind premium — a visual header/footer builder, transparent header, scroll-to-top button, and breadcrumbs. For budget-conscious projects, Kadence Free delivers more out of the box.
Kadence Blocks. The most feature-rich free block plugin. Advanced layout controls, row/column systems, advanced heading, icon list, info box, tabs, accordion, testimonials, and more — all with granular responsive controls. This competes with Elementor for layout capabilities while adding a fraction of the weight.
WooCommerce integration. Product gallery options, quick view, cart flyout, and shop page customization are included free. Kadence treats WooCommerce as a first-class use case, not a premium add-on.
Modern UI. The Customizer and block controls feel modern and intuitive. Clients find Kadence easier to navigate than GeneratePress.
Where Kadence falls short:
Slightly heavier than GeneratePress. ~30KB vs ~10KB. In practice, this difference is rarely perceptible to users, but it shows up in Lighthouse scores on a clean install.
Owned by StellarWP (Liquid Web). Some developers prefer independent products. Kadence was acquired by the StellarWP family (which also owns iThemes, LearnDash, and other WordPress products). The product has maintained quality post-acquisition, but the corporate ownership is a consideration.
Template variety. More templates than GeneratePress (~100+) but fewer than Astra (~250+). The template quality is high, but if you need a very specific industry starter, Astra has more options.
Pricing:
- Free version: Very capable (best free tier of the three)
- Kadence Pro: $149/yr (unlimited sites) or $699 lifetime
- Full Bundle: $199/yr (includes all Kadence products)
The pricing is higher than GeneratePress or Astra at the entry level, but the unlimited-sites model means the per-project cost drops quickly for agencies.
Astra — The Template Library
Why Astra is the right choice when you need a fast start with maximum template options.
Astra is the most popular WordPress theme by active installs (2M+). Its strength is the massive template library (250+ professionally designed starter sites) combined with broad compatibility across every page builder, LMS plugin, and ecommerce tool in the WordPress ecosystem.
Where Astra wins:
Template library. 250+ starter templates across every industry — restaurants, agencies, portfolios, shops, blogs, SaaS, fitness, legal, medical. Import a complete site design in one click, then customize. This is the fastest way to go from blank WordPress install to functional website.
Page builder compatibility. Astra works flawlessly with Elementor, Beaver Builder, Brizy, Gutenberg, and every other builder. The theme adapts its settings and controls to whichever builder is active.
Community and documentation. The largest community of the three themes means more tutorials, more third-party resources, and faster answers when you have questions.
Pricing. The Starter plan at $49/yr is the most affordable premium option. For a single client site, it is the lowest entry cost.
Where Astra falls short:
Slightly heavier than GeneratePress or Kadence. ~35KB on a clean install. Still lightweight compared to most themes, but measurably larger than GeneratePress.
Starter Templates plugin is separate. The templates are not built into the theme — they require the separate Starter Templates plugin, which adds its own weight during installation (though it can be deactivated after import).
Upselling in the dashboard. Astra's free version includes promotional notices for Astra Pro and related products. This is a minor annoyance for developers but can confuse clients.
Less developer-focused. The hook system exists but is not as comprehensive as GeneratePress. Developers who need granular control over template parts may find the abstraction limiting.
Pricing:
- Free version: Good basics, access to some starter templates
- Astra Pro Starter: $49/yr (1 site)
- Astra Pro Essential Bundle: $137/yr (unlimited sites, includes starter templates)
- Lifetime: $249 (unlimited sites)
Performance Benchmarks
Tested on identical clean WordPress installs (WordPress 6.x, PHP 8.2, same hosting, no additional plugins):
| Metric | GeneratePress | Kadence | Astra |
|---|---|---|---|
| Page weight (homepage) | ~10KB | ~28KB | ~34KB |
| HTTP requests | 2 | 4 | 5 |
| Lighthouse Performance | 100 | 98-99 | 96-98 |
| TTFB | Identical (hosting-dependent) | Identical | Identical |
| LCP | 0.5-0.8s | 0.6-0.9s | 0.7-1.0s |
| CLS | 0 | 0 | 0 |
In practice with real content, plugins, and images, the differences narrow significantly. WP Rocket + proper hosting makes all three themes load in under 2 seconds. The theme is rarely the performance bottleneck on a production site — plugins, images, and hosting matter far more.
Speed comparison — GeneratePress leads, Kadence balances, Astra offers versatility
My Recommendation by Project Type
| Project Type | My Choice | Why |
|---|---|---|
| Performance-critical WooCommerce | GeneratePress | Every KB matters when speed = revenue |
| Client-managed business site | Kadence | Best balance of power and usability |
| Quick-launch with template | Astra | Largest template library, fastest start |
| Developer building custom layouts | GeneratePress + GenerateBlocks | Most control, lightest output |
| Budget project (free theme only) | Kadence Free | Most features in the free tier |
| Agency building diverse client sites | Kadence (unlimited license) | Covers the widest range of project types |
What About Elementor / Bricks / Breakdance?
These are page builders, not themes. But the question comes up constantly.
If you use Elementor Pro: Use the Hello theme (Elementor's companion theme) or Astra/Kadence. GeneratePress works with Elementor but the combination is redundant — you are paying for two layout systems.
If you use Bricks Builder or Breakdance: These replace the theme entirely. You do not need a separate theme. Bricks includes its own theme layer.
If you use the block editor (no page builder): GeneratePress + GenerateBlocks or Kadence + Kadence Blocks. Both are excellent block-native workflows.
The Theme Matters Less Than You Think
Here is the honest truth: all three of these themes are excellent. Choosing between them is like choosing between three high-quality tools — you will get great results with any of them.
What matters more:
- Hosting quality — A fast theme on slow hosting is still slow
- Plugin choices — One heavy plugin negates any theme performance advantage
- Image optimization — Uncompressed images dwarf theme weight differences
- Content structure — Good IA and UX convert regardless of the theme
Pick one, learn it well, and focus your optimization energy on the factors that actually move the needle.
