Migrating from Butter CMS to SvelteKit makes the most sense if you're experiencing less flexible content modeling than sanity or contentful or outgrowing Butter CMS's architecture. SvelteKit is best for teams wanting excellent performance with a simpler, more intuitive framework.
You should migrate if: your Butter CMS site is slow, your hosting costs are climbing, you need developer flexibility, or you want to adopt a modern JAMstack architecture.
You might want to stay if: your Butter CMS site benefits from extremely easy for non-technical editors — feels like wordpress and you don't have JavaScript/TypeScript developers on your team. Butter CMS is genuinely easy to use, and that simplicity has value.
The migration itself is straightforward with LeaveWP — enter your Butter CMS URL, select SvelteKit, and download your content. The more important question is whether SvelteKit's architecture fits your team's skills and your project's long-term needs.
