I move nonprofits off WordPress to Sanity when a site has outgrown its plugin stack: multiple languages, several editors, and a design team that wants a modern front end. Sanity separates content from presentation, which removes most of the plugin security and maintenance burden that quietly sinks small nonprofit teams.
The short version
- WordPress is the right call for most small nonprofits. Move only when the plugin stack has become the project.
- In 2025, 91% of new WordPress vulnerabilities came from plugins, according to Patchstack. Fewer plugins means a smaller attack surface.
- Sanity is a headless content management system (CMS): your content lives behind an application programming interface (API), and any front end renders it.
- Multilingual support is native to Sanity, not a bolt-on plugin. That is the clearest advantage over a WordPress and WPML setup.
- Budget for a rebuild, not a swap. Sanity needs developers, so it fits funded nonprofits, not volunteer-run sites.
WordPress is fine until the plugins become the project
Most nonprofits should stay on WordPress, and I tell them so. It is free, every agency knows it, and a program manager can update a page without opening a ticket. I have shipped plenty of WordPress sites and I will ship more. The problem is not WordPress. The problem is what a growing nonprofit bolts onto it.
A five-year-old nonprofit site is rarely just WordPress. It is WordPress plus a page builder, a forms plugin, a translation plugin, a caching plugin, a security plugin, an events calendar, and a donation integration. Each one is code written by a different team on a different release schedule, running inside your site with full access to your database. That is where the risk concentrates. Patchstack, which maintains one of the largest WordPress vulnerability databases, reported 11,334 new vulnerabilities across the WordPress ecosystem in 2025. Of those, 91% were in plugins and 9% were in themes. Only six were in WordPress core, and all six were low priority. Read that breakdown again: the software the WordPress security team actually controls is not the problem. Your plugin drawer is.
For a nonprofit, that maintenance load is not a nuisance, it is a staffing decision they never agreed to make. Someone has to test and apply updates, watch for abandoned plugins, and restore the site when an update breaks the donation page the week before year-end giving. Most small nonprofits do not have that person. So the updates slip, and the site drifts toward the exact profile attackers look for. Moving to a headless CMS does not make security free, but it removes most of the plugins, and with them most of the surface area.
Headless means your content stops being trapped in a theme
Sanity is headless, which means it stores your content and hands it out through an API instead of rendering pages itself. Your words, images, and structured fields live in what Sanity calls the Content Lake, and you query them with GROQ, Sanity's query language, then render them with whatever front end your team wants: Astro, Next.js, or plain HTML. The content and the presentation are two separate things.
That separation is the whole point. In WordPress, your content is entangled with a theme and a page builder. Migrating designs, or reusing the same content across a website, an email, and a mobile app, means wrestling it out of markup that was never meant to be portable. In Sanity, the content is already structured data. A board bio is a name, a title, a headshot, and a paragraph, not a blob of HTML with a specific plugin's shortcodes buried inside. When you redesign the site in two years, the content does not move. Only the front end does.
There is a real editor benefit here too, not just a developer one. Sanity Studio, the editing interface, is configured to match your actual content model, so editors see the fields that exist and nothing else. No theme options they should not touch, no page-builder canvas where one dragged block breaks the layout. For a communications team of one or two people who are nervous about the site, that constraint is a feature. This blog you are reading runs on exactly that setup.
Multilingual is where the difference gets obvious
If a nonprofit serves more than one language community, the case for Sanity gets much stronger, because multilingual is native rather than a plugin. I have built and maintained multilingual sites on WordPress with WPML, and WPML is a capable plugin. It is also a plugin, which means it carries the update risk, the performance cost, and the compatibility friction of everything above. When WPML disagrees with your page builder or your theme, you are the one debugging it at 11pm.
Sanity treats translations as structured content. You can localize at the field level or the document level, keeping a Spanish and an English version of a page as first-class documents that share a schema. There is no translation layer sitting on top of your CMS hoping the other plugins cooperate. For a nonprofit that needs English plus Spanish today and might add a third language when a grant funds it, that architecture scales without adding a new point of failure each time. I default to assuming multilingual is coming, because for community-serving nonprofits it usually is.
The same structured approach helps with the unglamorous parts. Sanity's image pipeline serves and transforms images on the fly through a content delivery network (CDN), so you are not installing an image-optimization plugin and hoping it plays nicely with your caching plugin. Fewer moving parts, fewer things to patch.
What a WordPress-to-Sanity move actually costs a nonprofit
This is the part most vendors skip, so I will lead with it. A move to Sanity is a rebuild, not a swap, and you should budget for it that way. You are not installing a theme. You are modeling your content, building a front end, and migrating existing pages into structured documents. That is real developer time, and it is why I only recommend this to nonprofits that either have a technical partner on retainer or a project budget that can absorb a build.
The second cost is the ongoing developer dependency. In WordPress, a staffer can add a whole new page type by installing a plugin. In Sanity, adding a genuinely new content structure usually means a developer touches the schema. For content that already exists, editors are fully self-sufficient in the Studio. For new kinds of content, they are not. That trade is worth it for the right organization and a bad deal for a two-person shop that changes its site structure every quarter.
If your nonprofit is volunteer-run, updates its site twice a year, and has no development budget, stay on WordPress and just get disciplined about plugins: remove what you do not use, and put the rest on a real maintenance plan. If you are funded, multilingual, and tired of the plugin treadmill, Sanity is very likely the better home. If you want help deciding, my replatform checklist walks through the questions I ask before recommending a move, and I go deeper on the build-versus-buy math for membership and association sites in this piece on nonprofit platform decisions.
What this does not cover
This is a CMS architecture argument, not a full migration guide. I have not covered the redirect strategy you need so you do not lose search rankings in the move, which is its own project. I have not priced a specific build, because that depends on how many page types and languages you have. I have not compared Sanity against other headless options like Contentful or Strapi, which are also valid, or against Webflow, which suits a different kind of nonprofit. And nothing here applies to a site whose main job is a member portal or a complex donation platform, where the database and integrations matter more than the CMS. This is specifically about content-heavy, multilingual, communications-led nonprofit sites.
Frequently asked questions
Is Sanity free for nonprofits?
Sanity has a free tier that covers small projects, and paid plans scale with usage and team size. The larger cost for a nonprofit is not the license, it is the developer time to build the front end and migrate content. Check Sanity's current pricing directly, since plan limits change.
Can our staff still edit the site without a developer?
Yes, for content that already exists. Editors work in Sanity Studio, which shows only the fields you have defined, so day-to-day editing is arguably safer than a WordPress page builder. What they cannot do without a developer is create entirely new content structures, since that means changing the schema.
Will moving off WordPress hurt our search rankings?
It can if you skip the redirect strategy, and it will not if you do it properly. Rankings live at the uniform resource locator (URL) level, so every old URL needs a correct redirect to its new home. That planning is mandatory, not optional, on any replatform.
Do we lose our donation forms and integrations?
You reconnect them rather than lose them. Most donation platforms and email tools embed or connect through an API and work the same behind a Sanity front end. Map every integration before you start, because a missed one is what surprises teams mid-migration.
