Build a Full Stack AI Chatbot SaaS from Scratch (Chatbase Alternative) — Go, Next.js, Grit Framework

In this 2+ hour full build, I go from zero to a production-ready AI Agent SaaS called Nexora — a
direct Chatbase competitor with fairer pricing, a built-in live chat inbox, native WordPress plugin,
and Mobile Money payments for East African markets.
