Migrating from Prismic to Gatsby makes the most sense if you're experiencing slice machine adds build-step complexity to development or outgrowing Prismic's architecture. Gatsby is best for content-rich sites pulling data from multiple sources via graphql.
You should migrate if: your Prismic 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 Prismic site benefits from slice machine maps cms slices directly to frontend components and you don't have JavaScript/TypeScript developers on your team. Prismic is genuinely easy to use, and that simplicity has value.
The migration itself is straightforward with LeaveWP — enter your Prismic URL, select Gatsby, and download your content. The more important question is whether Gatsby's architecture fits your team's skills and your project's long-term needs.
