In Germany I often come across MEAN Stack: Mongo, Express, Angular and Node.JS. Also Java Spring, ASP.net and MySQL is still in use heavily here. Agencies and E-Commerce mostly have PHP backends and React frontends including Next.JS.

Hard to tell what the future holds, but those technologies will be around for longer. Adoption within the industry is much slower that you’d anticipate.

Personally I’d go with the GoX-Light-Stack (just made that up): Go + SQLite backend and HTMX frontend.
