react-starter-kit
Edge-native React template in a monorepo setup: Includes Vite frontend, Hono API, TanStack Router, shared types/utilities, and Terraform infra for scalable web development.
Project mention: Next.js VS react-starter-kit - a user suggested alternative | libhunt.com/r/next.js | 2025-08-08Hey everyone, if Next.js feels a bit heavy for your needs or you're after something with Bun's speed, I'd suggest React Starter Kit as a solid alternative: https://github.com/kriasoft/react-starter-kit. It's a production-ready monorepo boilerplate with React 19, TypeScript for end-to-end safety, Tailwind CSS, tRPC for seamless APIs, and effortless Cloudflare Workers deployment—perfect for scalable full-stack apps with less config bloat and edge-native performance. Give it a spin if you're building something fresh!
