Migrating from BigCommerce to Astro makes the most sense if you're experiencing revenue-based plan limits force upgrades as you grow or outgrowing BigCommerce's architecture. Astro is best for content-heavy websites that need maximum performance with minimal javascript.
You should migrate if: your BigCommerce site is slow, your hosting costs are climbing, your store needs a custom frontend, or you want to adopt a modern JAMstack architecture.
You might want to stay if: your BigCommerce site benefits from no transaction fees on any plan (unlike shopify) and you don't have JavaScript/TypeScript developers on your team.
The migration itself is straightforward with LeaveWP — enter your BigCommerce URL, select Astro, and download your content. The more important question is whether Astro's architecture fits your team's skills and your project's long-term needs.
