I'm the creator of templUI – an open source UI kit for Go + templ – and I just launched templUI Pro, a paid extension designed for production use.
The OSS version is still maintained and growing. Pro adds 200+ reusable UI blocks and a more structured setup for shipping templ apps quickly.
The stack is simple: Go, templ, HTML, Tailwind, and some light Vanilla JS. No frontend frameworks. No build tools.

Happy to answer questions or share more about how it’s built.
