I build on Sanity, so you would expect me to tell you Sanity wins. I am not going to, because the question is wrong. "Sanity vs WordPress" is framed as if one is better than the other, and that framing produces bad decisions in both directions: people force WordPress onto projects that needed structured content, and people put a non-technical client onto a headless setup they will never be able to manage. Neither tool is better. They are built for different situations, and the only useful question is which situation you are in.
The axis that actually decides it is this: who is building the site, and who is maintaining it afterwards.
What each tool is actually for
Sanity fits a structured, custom build with a development team behind it. You model the content deliberately, you build a bespoke frontend, and the team owns the code. The payoff is a content structure shaped exactly to the project and a frontend with no theme constraints, because you built it. The cost is that it assumes developers. Someone has to build and maintain the frontend, because Sanity gives you a content backend, not a finished website. With a dev team, that cost is just the normal cost of building software. Without one, it is a wall.
WordPress fits the opposite situation. It is a finished product aimed at an owner who wants to log in and run their own site without a developer on call. Themes give you a design without building one. Plugins give you features without writing them. A non-technical owner can add pages, swap images, install a contact form, and keep the thing running for years on their own. That autonomy is the entire point, and it is genuinely valuable. Dismissing WordPress as legacy baggage ignores that it does something Sanity deliberately does not: hand a complete, self-serviceable website to someone who is not a developer.
How to actually choose
So the decision is not about which is more modern or which the developer prefers. It is about matching the tool to the people.
If you have a development team and the project needs custom structure, a bespoke frontend, and content modelled for a specific purpose, Sanity is the right call. The structured content and the design freedom are worth it precisely because you have the people to use them. This is the world I work in, and for that world it is the better tool by a wide margin.
If the client is non-technical, budget-conscious, and wants to manage the site themselves with off-the-shelf themes and plugins and no ongoing developer relationship, WordPress is the right call. Putting that client on a headless build serves the developer's preferences, not the client's needs. You will have handed them something they cannot operate, and within a year they will be paying a developer for changes they expected to make themselves.
The mistake in both directions comes from the same place: choosing on hype or stack loyalty instead of on who has to build and run the thing. A developer who only knows one of these tools will reach for it regardless of fit, and the client pays for that mismatch later.
The honest version
The reason the versus is unfair is that they answer different questions. WordPress answers "how does a non-technical owner get and run a capable website." Sanity answers "how does a development team build a custom site with content structured exactly the way this project needs." Those are not competing answers to one question. They are answers to two different questions, and the projects that go well are the ones where someone correctly identified which question they were actually asking.
My honest take, as someone firmly in the Sanity camp for the work I do, is that I would still recommend WordPress without hesitation for the right client. A small business owner who wants to manage their own content, on a tight budget, with no developer in their future, is better served by WordPress than by anything I would build them on Sanity, and pretending otherwise would be selling them my preference instead of their solution. Knowing when the tool you love is the wrong choice is most of what separates a useful recommendation from a biased one.
