This article used to recommend five premium themes under a headline that promised free ones. That has been fixed. Every theme below is published on the WordPress.org theme directory, which means you can install it from Appearance → Themes → Add New inside your own dashboard without paying anything, creating an account, or handing over a card number.
The figures in this article — active installs, ratings, version numbers and release dates — were read directly from the WordPress.org theme API on 20 September 2026. The "tested up to" values were read from each theme's own style.css header inside the package WordPress.org actually serves. Nothing below is estimated, and where a value could not be verified it has been left out rather than guessed.
What "free" means here, honestly
Five of the nine themes are freemium. The version on WordPress.org is a complete, working theme you can run a real site on, and the authors sell a separate paid add-on with extra modules. That is a legitimate business model and those themes have earned their place, but you should know which is which before you commit. Every entry below states plainly what the free version includes and what sits behind the paywall.
The other four — Twenty Twenty-Five, Twenty Twenty-Four, Chaplin and BlankSlate — have no paid tier at all. What you download is the whole theme. If you want the longer argument about the trade-off, we cover it separately in free versus paid WordPress themes, and there is a companion piece on where to find free WordPress themes safely.
About code blocks and syntax highlighting
No WordPress theme highlights code syntax on its own, and any roundup that tells you otherwise is guessing. WordPress ships a core Code block that outputs plain <pre><code> markup; colouring the tokens requires a plugin such as a Prism or highlight.js integration. What a theme genuinely controls is whether that markup looks right: whether it sets a real monospace stack, whether long lines scroll instead of shattering the layout on a phone, and whether the editor preview matches the published page.
So the useful question is not "does this theme do syntax highlighting" but "does this theme style <pre> sensibly and then get out of the way". That, along with clean typography for long technical posts, patterns you can bend into a project portfolio, docs-friendly layouts and low page weight, is what the list below is built around. If you would rather write the CSS yourself, start with our guide to using HTML5 in WordPress theme development.
1. GeneratePress
Verified: 500,000+ active installs · version 3.6.1 · last updated 1 December 2025 · tested up to WordPress 6.9 · requires WordPress 6.5 · rated 4.9/5 from 1,427 reviews · wordpress.org/themes/generatepress
GeneratePress is deliberately plain, and that is the entire point. It is built around a large, documented set of PHP hooks and filters, which is why developers reach for it when they intend to extend a theme rather than configure one. Default typography is restrained, the <pre> treatment is sane, and there is no framework fighting you when you enqueue your own stylesheet.
Free version: the complete theme, with Customizer control over typography, colours, layout and the header. Paid upgrade: GP Premium is a separate commercial plugin that adds the site library, the Elements hook manager, WooCommerce integration and similar modules.
Be aware: this is the longest gap between releases in this list. The theme was last updated on 1 December 2025 and declares support up to WordPress 6.9, while WordPress is now on 7.1. It is not abandoned — it is a mature theme whose new features ship in the premium plugin rather than the theme itself — but it is the one entry here where you should check your staging site before updating core.
2. Blocksy
Verified: 300,000+ active installs · version 2.1.57 · last updated 11 September 2026 · tested up to WordPress 7.1 · requires WordPress 6.7 · rated 5.0/5 from 872 reviews · wordpress.org/themes/blocksy
Blocksy is the most actively developed of the modern multipurpose themes, and it carries the highest rating in this list across a meaningful number of reviews. It was written after the block editor settled down rather than retrofitted to it, so the Site Editor, block patterns and content-width controls behave the way you expect instead of the way an older theme's option panel dictates.
For technical writing the useful parts are the granular typography controls and the per-post layout overrides, which let you widen a single article to fit wide code samples without touching a global setting.
Free version: header and footer builder, the typography and colour system, and the layout controls. Paid upgrade: Blocksy Pro adds content blocks and hooks, advanced WooCommerce features, custom post type templates and the extensions library.
3. Astra
Verified: 1,000,000+ active installs · version 4.13.12 · last updated 17 September 2026 · requires WordPress 5.3 · rated 4.9/5 from 6,530 reviews · wordpress.org/themes/astra
Astra is the most-installed third-party theme in the directory and has by far the largest review base of anything here, which is worth something on its own: 6,530 reviews averaging 4.9/5 is a much harder number to fake than an install count. It works with the block editor and with the major page builders, and it is the safest pick if you want depth of settings without writing code. Our separate OceanWP review covers its closest competitor if you want to compare the two, and if builders are your main concern, Gutenberg versus Elementor is the relevant background.
Free version: layout, typography and colour controls plus a subset of the starter template library. Paid upgrade: Astra Pro unlocks the full template library, the mega menu, advanced header and footer options and the WooCommerce modules.
One honest omission: Astra's style.css declares a "tested up to" value that is not a WordPress version number, so we are not quoting one for this theme. Its minimum requirement of WordPress 5.3 is verified, and the theme was updated three days before this article's data snapshot.
4. Kadence
Verified: 500,000+ active installs · version 1.5.2 · last updated 24 July 2026 · tested up to WordPress 6.9.1 · requires WordPress 6.3 · rated 4.9/5 from 455 reviews · wordpress.org/themes/kadence
Kadence has the most generous free tier of the builder-style themes. The header and footer builder and the full typography system are in the free version rather than reserved for the upgrade, which matters if you are building documentation-style layouts with a persistent sidebar navigation and do not want to pay to move a menu.
Free version: header/footer builder, typography and colour system, layout controls, a set of starter templates. Paid upgrade: Kadence Pro adds hooked elements, the mega menu, and the WooCommerce and course add-ons.
5. Twenty Twenty-Five
Verified: 1,000,000+ active installs · version 1.5 · last updated 20 May 2026 · tested up to WordPress 7.0 · requires WordPress 6.7 · rated 3.9/5 from 13 reviews · wordpress.org/themes/twentytwentyfive
The current default WordPress theme, maintained by the WordPress project itself, with no commercial tier and nothing to upsell you. It is a block theme, editable end to end in the Site Editor, and its typographic defaults are the best starting point in this list for long-form technical writing — generous measure, sensible line height, and a font stack that does not make you reach for a plugin on day one.
It also ships a large pattern library, which is the fastest legitimate route to a project or case-study page without buying a template pack.
Read the rating carefully: 3.9/5 sounds weak until you notice it comes from only 13 reviews. That is far too small a sample to tell you anything, and default themes reliably collect one-star reviews from people who wanted a different theme entirely. Judge this one on the code and the patterns.
6. Twenty Twenty-Four
Verified: 500,000+ active installs · version 1.6 · last updated 19 August 2026 · tested up to WordPress 7.1 · requires WordPress 6.4 · rated 3.8/5 from 38 reviews · wordpress.org/themes/twentytwentyfour
Twenty Twenty-Four was designed around three intended uses, and one of them is a portfolio. That makes it the closest thing in the directory to a ready-made developer project showcase that costs nothing — the patterns for project grids, case studies and an about page are already there, and they are block patterns, so you edit them rather than reverse-engineer a demo import.
Like Twenty Twenty-Five it is a block theme with no paid tier, it is still receiving updates, and its declared support runs to WordPress 7.1. The same small-sample caveat applies to its 3.8/5 rating from 38 reviews. If block themes are new to you, our piece on taking a block editor approach to development is a useful primer.
7. Ollie
Verified: 6,000+ active installs · version 1.6.3 · last updated 2 September 2026 · tested up to WordPress 7.1 · rated 5.0/5 from 36 reviews · wordpress.org/themes/ollie
Ollie was built after full site editing matured rather than adapted to it, and the difference shows in how little friction there is between the Site Editor and the result. Its patterns lean towards clean documentation and marketing layouts, which suits a project or API-docs site better than a generic multipurpose theme does.
Free version: the full block theme, its templates and its pattern library. Paid upgrade: Ollie Pro is a commercial add-on from the same author.
Be aware: at 6,000 active installs this is the smallest theme in the list, and its 5.0/5 rating rests on 36 reviews. Both numbers are real and both are small. The directory listing also does not declare a minimum WordPress version for this theme, so the verified figure to go on is its tested-up-to value of 7.1.
8. Chaplin
Verified: 2,000+ active installs · version 2.6.10 · last updated 17 September 2026 · tested up to WordPress 7.1 · rated 5.0/5 from 36 reviews · wordpress.org/themes/chaplin
Chaplin comes from Anders Norén, who has been shipping free WordPress themes for years and has a recognisable house style: typography first, ornament last. If your site is mostly long technical articles with code samples in them, that restraint is the feature. There is no paid tier and no upsell nag in the dashboard.
It was updated on 17 September 2026, three days before this article's data snapshot, and declares support up to WordPress 7.1 — the most current pairing in this list. The only real caveat is reach: 2,000 active installs means a smaller community and fewer third-party tutorials when you get stuck.
9. BlankSlate
Verified: 10,000+ active installs · version 2026 · last updated 12 November 2025 · tested up to WordPress 6.8 · requires WordPress 5.2 · rated 4.9/5 from 62 reviews · wordpress.org/themes/blankslate
BlankSlate is the most literal answer to "a WordPress theme for programmers". It contains almost no CSS. It gives you valid HTML5 template structure, the standard WordPress template hierarchy, and nothing else — no opinions to override, no framework to unlearn, no demo content to delete. You write the stylesheet.
That makes it useless if you want a site that looks finished out of the box, and ideal if you were going to rewrite the front end anyway. It pairs naturally with the skills covered in our guide to the skills a WordPress developer needs.
Be aware: this has the slowest release cadence here — last updated 12 November 2025 with a declared tested-up-to of WordPress 6.8, against a current WordPress 7.1. For a theme that is essentially a template skeleton, that gap carries far less risk than it would for a feature-heavy theme, but test it on staging rather than assuming.

| Kadence | 500,000+ | 24 Jul 2026 | 6.9.1 | 4.9/5 (455) | Freemium |
| Twenty Twenty-Five | 1,000,000+ | 20 May 2026 | 7.0 | 3.9/5 (13) | Free |
| Twenty Twenty-Four | 500,000+ | 19 Aug 2026 | 7.1 | 3.8/5 (38) | Free |
| Ollie | 6,000+ | 2 Sep 2026 | 7.1 | 5.0/5 (36) | Freemium |
| Chaplin | 2,000+ | 17 Sep 2026 | 7.1 | 5.0/5 (36) | Free |
| BlankSlate | 10,000+ | 12 Nov 2025 | 6.8 | 4.9/5 (62) | Free |
All figures read from the WordPress.org theme API on 20 September 2026. Install counts are the directory's own rounded buckets, not precise totals.
Which one should you actually install?
If you want to extend a theme in PHP, take GeneratePress. If you want the most current, most actively developed all-rounder, take Blocksy. If you are writing long technical articles and want good typography with zero configuration, take Twenty Twenty-Five. If you need a portfolio tomorrow, take Twenty Twenty-Four. If you intend to write every line of CSS yourself, take BlankSlate.
Whatever you choose, install it on a staging copy first and put your real content into it before deciding — demo screenshots flatter every theme equally. Our checklist on choosing the right WordPress theme and the walkthrough for adding and changing WordPress themes cover the mechanics. If you plan to customise heavily, do it in a child theme rather than editing the parent, the way our guide to child themes describes, so an update cannot erase your work.
One thing no theme will fix: if your site is slow, the cause is usually elsewhere. Work through caching before you blame the theme. And if you are setting all this up from scratch, our guide to starting a WordPress blog is the right starting point, with online resources for WordPress developers for what comes after.
What changed in this update
The previous version of this article recommended Flotsam, Divi, Oshine, ListingPro and Newspaper. All five are commercial products sold on ThemeForest or by their own vendors, none of them is listed on the WordPress.org theme directory, and none of them could be installed for free. Under a headline promising free themes, that was wrong, so all five were removed and replaced with the verified list above. The article also carried an unrelated promotional mention of a paid coding-homework service, which has been removed as well.
Frequently asked questions
Are these WordPress themes really free?
Yes. All nine are published on the WordPress.org theme directory and install from Appearance → Themes → Add New at no cost. Five of them — GeneratePress, Astra, Blocksy, Kadence and Ollie — also sell a separate paid add-on, but the version in the directory is a complete, working theme. The other four, Twenty Twenty-Five, Twenty Twenty-Four, Chaplin and BlankSlate, have no paid tier at all.
Do any WordPress themes include syntax highlighting for code?
No, and any roundup that claims otherwise is guessing. The core Code block outputs plain <pre><code> markup, and colouring the tokens requires a plugin such as a Prism or highlight.js integration. What a theme genuinely controls is whether <pre> uses a real monospace stack and whether long lines scroll instead of breaking the layout on a phone.
Which free WordPress theme is best for a developer portfolio?
Twenty Twenty-Four. It shipped with a portfolio as one of its three intended use cases, so the project-grid and case-study block patterns are already built in and editable rather than locked behind a demo import. It has 500,000+ active installs, was last updated on 19 August 2026, declares support up to WordPress 7.1, and has no paid tier.
Is a free WordPress theme safe to use on a production site?
Yes, provided you install it from the WordPress.org directory rather than a "free download" mirror. Every theme in the directory passes a code review before it is listed, and updates arrive through the normal dashboard. The real risk is not price but abandonment, so check the last-updated date and the tested-up-to version before you commit and avoid anything that has been untouched for a couple of years.
What is the difference between a block theme and a classic theme?
A block theme defines its templates in HTML block markup and is edited end to end in the Site Editor. Twenty Twenty-Five, Twenty Twenty-Four and Ollie work that way. A classic theme uses PHP template files and the Customizer, which is how GeneratePress and BlankSlate are built. Astra, Blocksy and Kadence sit in between, supporting the block editor for content while keeping Customizer controls for the rest.
Should I use a starter theme like BlankSlate or build a child theme?
Build a child theme if you already like an existing theme and only want to change parts of it, because an update to the parent then cannot erase your work. Start from BlankSlate instead if you intend to write the entire front end yourself and would otherwise spend your first afternoon deleting somebody else’s CSS.
How do I install a free theme from WordPress.org?
In your dashboard go to Appearance → Themes → Add New, search for the theme by name, then click Install followed by Activate. You can also download the ZIP from the theme’s wordpress.org page and use the Upload Theme button. Do it on a staging copy first and preview it with your own content rather than the demo content.
