Build and Deploy a SaaS AI Website Builder | Next.js 15, React, Inngest, Prisma | Lovable clone

Tavsif:

In this video, we’re building an AI-powered app builder from start to finish. You’ll learn how to generate full-stack applications from simple prompts using programmable AI agents powered by Inngest. We’ll use models like OpenAI, Anthropic, and Grok to handle code generation, and execute everything inside secure cloud sandboxes with E2B and Docker. We’ll also cover the agent architecture, background job orchestration, project dashboard, authentication and billing with Clerk, and a full Git workflow with AI‑assisted PR reviews from CodeRabbit. Built with Next.js 15, React 19, Tailwind v4, and a fully modern AI‑first toolchain.
