🗺️ next-dynamic-sitemap
I built next-dynamic-sitemap because I was tired of manually maintaining sitemap.xml files in Next.js projects — especially once dynamic routes get involved. Static routes are easy, but once you start using generateStaticParams or getStaticPaths, it becomes frustratingly manual to keep everything in sync.
This tool automates that. It crawls your App Router and Pages Router trees at build time and generates a complete sitemap.xml, including dynamic routes with custom lastModified timestamps pulled straight from your static param functions. That means your sitemap stays accurate — and search engines stay happy — with zero extra effort.
✅ App Router support (generateStaticParams)
✅ Pages Router support (getStaticPaths)
✅ Auto-skips non-static routes
✅ Pulls lastModified metadata directly from your code
✅ Plays nicely with .env — no weird config files or magic strings
Just run it before your Next.js build, and you’re done.
Looking for runtime sitemap support instead?
Check out next-runtime-sitemap — a complementary tool that generates sitemap.xml dynamically at request time, perfect for serverful deployments or hybrid solutions.
I use these tools in most of my Next.js projects now. They’re simple, smart, and don’t try to do too much — which is exactly how I like my tooling.
