MyBB
Themes at community.mybb.com. The largest free collection of the four, and the easiest to modify by hand if you know a little CSS.
Themes & Templates
Free themes that stay fast on a small plan
Curated for weight rather than looks, because on 5GB of storage and 10GB of bandwidth a month the theme you choose is one of the few decisions that genuinely moves those numbers. No affiliate links, and the licences are spelled out.

How this list is different
Two things worth saying before the lists.
Almost every “best free themes” article is affiliate content. Theme commissions are substantial, and the ordering of most lists reflects payout rates rather than quality. That is not a conspiracy, it is just how the niche is monetised — but it means the rankings carry very little information. There are no affiliate links on this page and nobody pays us for placement.
None of these themes are ours, and none are included with hosting. They are free work published by their own authors under their own licences. You install them yourself; we just run the server. We have linked to the official source for each one, where you can see a live demo — we are not reproducing anyone’s screenshots here.
Why weight is the thing we sorted on
A theme adding 300KB of CSS and JavaScript to every page view burns through a 10GB monthly allowance roughly ten times faster than one adding 30KB. On a large plan that is invisible. On this one it is the difference between a few thousand visitors a month and a few tens of thousands.
It also has nothing to do with how the site looks. The weight in a bloated theme is almost always configuration options you never open, not design you can see.
WordPress
Six lightweight WordPress themes
All free on wordpress.org, all actively maintained, all installable from your dashboard in about thirty seconds.
| Theme | Roughly adds | Best for |
|---|---|---|
| GeneratePress | Under 10KB CSS | The lightest of the mainstream options. Deliberately minimal out of the box — you build the design rather than picking a demo. |
| Astra | Under ~50KB CSS | The safe all-rounder. Large starter-template library, works with any editor, enormous community if you get stuck. |
| Kadence | ~30KB CSS | The best free customiser of the group. Header and footer builders in the free version, tight block-editor integration. |
| Blocksy | Comparable | Strong full-site-editing support and generous free tier. Good if you want to design visually without a page builder. |
| Neve | Comparable | Business and agency layouts, header/footer builder, decent starter sites. |
| Twenty Twenty-Five | Minimal | Still the current default: WordPress skipped a 2026 theme entirely, and Twenty Twenty-Seven is not due until late 2026. No upsell, no companion plugin, maintained by the core team. |
Weights are the authors’ published figures or widely reported measurements for a clean install, not our own benchmarks — and a clean install is not what you will end up running. Treat them as a starting order of magnitude. All six are free on wordpress.org; each has a paid tier or companion plugin, and none of them require it.
Picking one
Which should you actually choose?
If you want a single answer: Kadence or Astra for most people, GeneratePress if you are comfortable building the design yourself and want the absolute lightest option, Twenty Twenty-Five if you would rather have no upsell path at all.
Install from Appearance → Themes → Add New inside WordPress and search by name. Installing from the dashboard means you get updates automatically, which is the entire reason to prefer it over uploading a ZIP from a third-party site.
The thing that actually slows a WordPress site
Honestly? Not the theme. It is unoptimised images, by a wide margin, followed by having twenty plugins where five would do. A photo straight off a phone is around 4MB; the same image sized properly and served as WebP might be 80KB. That single change matters more than every theme on this list combined.
Worth reading alongside this: why NVMe is faster, and when it does not matter.
Static HTML
Free HTML template libraries
For static sites you upload yourself. Faster than any CMS, nothing to update, almost nothing to attack — and the licence is the part people skip.
| Library | Licence | Credit link required? |
|---|---|---|
| HTML5 UP | Creative Commons BY 3.0 | Yes — keep the footer credit, or buy a licence to remove it |
| Start Bootstrap | MIT | No |
| Cruip | MIT (free templates) | No |
| TemplateMo | CC BY (varies by template) | Check per template |
| Colorlib | Varies by template | Check per template |
| Bootstrap examples | MIT | No — official starter layouts, not full designs |
Licences change and vary per template. Always read the licence file in the download rather than trusting a table on someone else’s website, including this one.
Licences
The part most lists leave out
Read the licence, genuinely
This is where free HTML templates catch people out, and it is a legal question rather than a stylistic one.
MIT means do what you like, including commercially, with no attribution required. Creative Commons BY means you must keep the author’s credit visible — usually a line in the footer. Quietly deleting that line on a CC BY template is a licence breach, and it is the single most common mistake made with free templates.
HTML5 UP is the one to be careful with: excellent templates, CC BY 3.0, and they sell a licence specifically to remove the credit. If the footer link bothers you, pay for that rather than deleting it.
Deploying one
Download, unzip, and upload the contents into public_html using the file manager or FTP. Your entry point must be named index.html, lowercase — Linux is case-sensitive and Index.html will give you a directory listing instead of a website. Full walkthrough: uploading files via FTP.
A static site can still have a working contact form — PHP is available on every account whether or not you use it otherwise. See free HTML hosting.
Forum software
Where to find forum themes
Deliberately no named recommendations here — individual forum themes go unmaintained faster than anything else on this page, and a list would be wrong within two years. The official directories stay current.
phpBB
Styles at phpbb.com/customise. Fewer modern designs than MyBB, but the ones that exist tend to be maintained for years.
SMF
Themes at custom.simplemachines.org. Smaller selection; check the version compatibility field before downloading anything.
Flarum
Extensions at discuss.flarum.org. Flarum theming is mostly colour settings plus custom CSS rather than downloadable skins — the default is good enough that most forums just recolour it.
Before you install
Four checks that save a bad afternoon
Four checks before you install a forum theme, in order of how much trouble they save:
1. Does it state your exact version? A MyBB 1.8 theme will not work correctly on a different major version. This field is on every directory listing and is the most common cause of a broken-looking forum.
2. When was it last updated? Forum software patches security issues regularly, and themes override template files. An old theme can reintroduce a vulnerability the core has already fixed.
3. Is it responsive? Plenty of older forum themes predate mobile mattering. Most of your visitors are on a phone. Open the demo on your own phone before committing.
4. How many external requests does it add? Some themes pull fonts, icon sets and JavaScript from four different CDNs. Each is a connection to a server you do not control, and your page waits for all of them.

Exactly what “free” means here
- Free for 30 days. A full hosting account with nothing held back — no feature restrictions during the trial.
- No card details required to start. You can sign up and run your site for the whole 30 days without giving us any payment information.
- Nothing can be charged automatically, because we have nothing to charge. Payment details are only taken if you decide to continue.
- Then £0.99/month if you choose to carry on. That is the ongoing price — it does not rise after the first year.
- No setup fee and no hidden charges of any kind.
- You bring your own domain. Traxio does not sell domain names, so you will need one you already own or register elsewhere.

Questions
Questions about themes
Are these themes included with Traxio hosting?
No, and it would be misleading to imply otherwise. They are free themes published by their own authors, which you install yourself — WordPress themes from the dashboard in about thirty seconds, HTML templates by uploading a folder. We host the site; the themes are the authors’ work and their licences are theirs, not ours.
Do you earn commission on any of these?
No. There are no affiliate links on this page or anywhere on this site, and nobody pays for placement. Worth knowing when reading any “best free themes” list, most of which are ordered by commission rate rather than quality — the WordPress theme space in particular is one of the most affiliate-saturated corners of the web.
Why do you keep talking about theme weight?
Because the plan is 5GB of storage and 10GB of bandwidth a month, and a heavy theme spends both. A theme adding 300KB of CSS and JavaScript to every page view will burn through 10GB roughly three times faster than one adding 30KB. On a small plan the theme choice is one of the few decisions that genuinely moves that number.
Will a lightweight theme look basic?
It used to be a real trade-off; it mostly is not now. Block editing and starter templates mean the lean themes ship the same layouts as the heavy ones and load the styling only where used. The weight in a bloated theme is usually options you never touch, not design you can see.
Can I use a premium theme on Traxio hosting?
Yes — nothing here is restricted to free themes. Buy whatever you like and install it normally. Just check its weight before committing, because a heavy premium theme costs you bandwidth in exactly the same way a heavy free one does.
What about “nulled” themes — premium ones offered free elsewhere?
Do not. Pirated premium themes are one of the most reliable ways to get a site compromised: they are routinely distributed with backdoors, and the person who repackaged them is not doing it out of generosity. It also breaches our acceptable use policy. Install from wordpress.org or the author’s own site.
Is there a Twenty Twenty-Six theme?
No — WordPress skipped a default theme for 2026 entirely, choosing to put the effort into the block editor and core performance instead. Twenty Twenty-Five remains the current default, and Twenty Twenty-Seven is planned for late 2026. If a list tells you to install Twenty Twenty-Six, that list was not checked.
How do I know a theme is still maintained?
On wordpress.org, check the “last updated” date and the active install count on the theme’s page. Anything untouched for over a year deserves suspicion; over two years and you should assume it is abandoned. An unmaintained theme is a future security problem, not just a stale design.
Can I change theme later without losing my content?
Your posts, pages, images and comments live in the database and are untouched by a theme switch. What does not transfer is theme-specific layout — header and footer builder settings, custom widget areas, page-builder blocks tied to that theme. Take a backup from DirectAdmin first, and expect to spend an hour rebuilding the furniture.
