For a business site, the choice between Astro and WordPress comes down to who will change the site after launch, and how often. If people outside your development team will publish every week, or the site depends on plugins for a shop, bookings, or memberships, WordPress is the better fit; if the site changes mostly through a developer, Astro removes most of what WordPress asks you to maintain. Either platform can serve a visitor the same page, so most of the difference shows up after launch, in who can make a change and what has to be kept up to date.
This assumes the site is mostly content: pages, a blog, a contact form. Whether a marketing site needs a JavaScript framework at all is a separate question, and this post starts once that one is settled.
Two ways to run the same site
WordPress assembles each page on a server when someone asks for it, pulling the content from a database and running it through the theme and any plugins, with caching to skip some of that work on busy pages. You log into an admin to write posts, edit pages, and install plugins. W3Techs counted it on about 40% of all websites in October 2026.
Astro builds every page into a finished HTML file before anyone visits, and the host hands those files out as they are. There is no admin to log into, no database, and nothing running when a visitor arrives, unless you add them. By default it sends each page to the browser as HTML and CSS with no JavaScript, and adds JavaScript only to the parts of a page that ask for it.
Astro vs WordPress, side by side
WordPress trades ongoing upkeep for an editor anyone can use and a plugin for nearly every job. Astro gives up the editor in exchange for very little to maintain.
| WordPress | Astro | |
|---|---|---|
| Who edits content | Anyone with a login, in an editor in the browser | A developer, in the site’s files, unless you add an editor |
| What runs when someone visits | PHP and a database assemble the page | Nothing, because the page was built ahead of time |
| What needs updating | WordPress itself, the theme, every plugin, and PHP on the server | The tools that build the site, upgraded from time to time |
| Where an attacker can reach | The login page and every plugin, and through them the database | No login, database, or plugins on a static site |
| Adding a feature | Install one of over 70,000 free plugins | Write it, add a package, or connect a service |
| Hosting | A server that runs PHP and a database | Plain files, with nothing to run on a server |
| Who can maintain it later | More developers work in it | Fewer developers work in it: about a third as many in Stack Overflow’s 2025 survey |
| Leaving it | Posts and pages export; the theme and plugins stay behind | Content kept in text files moves anywhere; the templates are Astro’s |
Most of those rows come from one difference in timing: WordPress does its work when a visitor arrives, and Astro does it before anyone visits.
Who will actually edit the site
The editor is WordPress’s biggest advantage, and it only pays for itself if someone outside the development team uses it.
Before founding BAM, I spent more than three years keeping a B2B company’s WordPress site running, and in that time I published every one of its 60-plus blog posts myself, because nobody at the company ever made a change in WordPress. Each post needed layout HTML pasted in by hand to match the posts before it, which is the kind of content baked into markup that makes every later redesign harder. The site still carried the full upkeep of WordPress, including an events plugin that loaded on every page whether or not the page showed an event, for an editor that nobody at the company used.
So answer the questions that decide it from what your team does today, rather than from what a new editor might encourage it to do:
- Who will publish to the site? Name a person or a role, because “the marketing team” tends to mean whoever has time that week.
- How often will they publish? Every week, or a few times a month.
- Have they published to your current site in the last six months? If they have not, ask why. A team that writes posts and hands them to someone else to publish has the demand, and its editor is what failed, which is a case for an editor built around its content. A team with nothing to publish would be paying to keep a feature it does not use.
- What does the site need beyond pages? A shop, bookings, memberships, gated downloads.
A named marketer who publishes every week, and already does on the current site, is the case WordPress was built for. A developer making changes a few times a month is the case where Astro gives you the same site without the parts nobody will open.
There is a middle path. An Astro site can have an editor too, through a headless CMS (a content system with an admin but no website of its own, which hands its content to the site when the site is built) or a tool that edits the site’s files from a browser. Astro’s documentation had setup guides for 45 of them in October 2026, WordPress itself among them. Because the pages are built ahead of time, a change made in the CMS goes live when the site is next rebuilt, and seeing a draft in place before it publishes takes setup of its own. Each one is also another service to set up, often pay for, and keep an account on, so it suits a team that will really use the editor and still wants Astro’s lighter upkeep.
What each one asks you to maintain
WordPress asks for steady, small upkeep for as long as the site is live, while Astro asks for an occasional upgrade and very little in between.
Our own site is the Astro side of that. It shipped 48 releases between March and October 2026, and its first major Astro upgrade after launch, from version 6 to 7 in September, was a single change to the list of tools the site is built with, plus a security setting we tightened at the same time. No page or component changed, and nothing needed fixing afterwards. There is no login page, database, or plugin to patch, and the static site costs nothing to host. Our posts are text files kept with the site’s code and published by adding a file, which suits us because the person publishing is a developer, and it would not suit a marketing team. The two parts that need a server sit outside the site: the contact form posts to a form service, and our free AI citeability checker calls a small server of its own, which is the part we pay to host.
That record is the best case, and a static site still needs looking after. The accounts that can change it (the host, the code repository, the domain) need strong sign-in protection, because whoever controls them controls the site. Features on an Astro site come from add-on packages, which need upgrading along with the tools that build the site and carry their own security risk, and an upgrade put off for a few years turns into a much bigger job when it finally has to happen.
The WordPress side is manageable, and it never stops. On a new install, WordPress updates itself by default, and plugins and themes can be switched to update automatically, but WordPress itself, the theme, every plugin, and the PHP version on the server still move on their own schedules, and an update to one can break another. On the site I looked after before BAM, that meant 19 plugins, updated once a month or sooner when a critical fix came out, with a check of the site after every round to make sure it still worked and looked right; a regular monthly round took about an hour. None of those updates broke anything, and the check still had to happen every time.
Plugins are where most of the vulnerabilities turn up: Patchstack, which tracks WordPress vulnerabilities, counted 11,334 new ones in 2025, 91% of them in plugins and 9% in themes. Keeping that list short is most of doing WordPress properly.
When WordPress is the better choice
WordPress is the better choice when people outside the development team publish often, or when the site’s job depends on plugins.
- Editors who publish every week. The editor is the point, and a WordPress site built properly, with blocks shaped to your own content, keeps it simple for them.
- Features that already exist as mature plugins. On WordPress, a shop, bookings, and memberships are each a plugin to install and configure, sometimes a paid one. On Astro, each one is code someone writes or a third-party service you connect, often for a fee.
- The widest pool of people who can look after it. In Stack Overflow’s 2025 developer survey, 13.6% of respondents had done extensive development work in WordPress over the past year, against 4.5% in Astro. That matters most when there is no developer on your staff and you will need to hire one later.
- A WordPress site that works and that people use. Fix what is wrong with it where it stands. Replacing an editor your team relies on is an expensive way to solve a plugin problem.
When Astro is the better choice
Astro is the better choice when the site changes mostly through a developer and you want as little as possible to maintain.
- Changes come through a developer, a few times a month, or through a small team that is comfortable editing text files. A missing editor costs nothing if nobody would have opened it.
- You want the smallest attack surface and the least upkeep. That matters most when nobody on your staff is watching the site week to week.
- The dynamic parts are few, and a service can handle each one. A contact form, a booking widget, or search can each be a service the site calls.
- You want speed without tuning for it. In HTTP Archive’s August 2026 data, 71.0% of Astro sites passed Core Web Vitals for mobile visitors, against 48.7% of WordPress sites. The two groups differ in more than their platform: the data holds about 44,000 Astro sites against 2.75 million on WordPress, built by different people for different reasons, so the gap describes those sites rather than promising anything about yours. A page that arrives already finished still has less that can go wrong on the way.
If your site is on WordPress today
Moving an existing WordPress site to Astro is a rebuild. When we ported a WordPress site with 147 posts, 30 pages, and three custom plugins to an early version of an Astro-based CMS, the content imported cleanly, and every template and all three plugins needed rewriting from scratch. Any layout pasted into posts comes along with the content, and someone has to clean it up on the way.
So the switch belongs at a rebuild that was coming anyway, and redesign versus rebuild is the call that decides whether one is.
Choose for the person who will change it
Most comparisons of Astro and WordPress argue about speed and security, and both matter, but the choice between them rests on the question this post started with: who will change the site after launch, and how often. Settle it before the build starts, and from what your team did last quarter, since changing your mind afterwards costs the rebuild described above.
