LaunchAI

Most AI starter kits hand you infrastructure. LaunchAI hands you a product. Built on the stack you already use — Next.js + the Vercel AI SDK — it ships persistent streaming, multi-provider routing, agents, and RAG, plus two things the others skip: a production design system so your v1 looks shipped, and per-user token + cost metering so you can price it without a surprise invoice. One-time purchase, own the source, no subscription.
