Build and Deploy an AI Automation Platform | Next.js 15, React, Better Auth | Zapier & N8N Clone

Part 2 of our Nodebase tutorial continues the journey by completing the execution engine and adding remaining integrations. You'll learn how to implement workflow execution with variables and templating, build trigger nodes that respond to real-world events, integrate multiple AI providers with encrypted credential management, and create messaging integrations. Additional coverage includes execution history with error tracking, extra authentication providers, and deploying the entire platform to production. The video features a visual workflow builder, trigger nodes such as Webhook, Google Form, Stripe, and Manual, AI nodes for OpenAI, Claude, and Gemini, messaging nodes for Discord and Slack, an HTTP request node, background job execution with Inngest, Polar payments and subscriptions, Better Auth authentication, a React Flow canvas, Prisma ORM and Neon Postgres, TypeScript and tRPC type safety, Sentry error tracking and AI monitoring, CodeRabbit PR reviews, Next.js 15 App Router, and a production‑ready SaaS design. 00:00 Intro & Demo 01:50 18 Node Execution 01:06:58 19 Node Variables 01:29:53 20 Node Templating 02:01:36 21 Node Realtime 02:46:27 22 Google Form Trigger 03:57:27 23 Stripe Trigger 04:30:54 24 AI Nodes 05:49:42 25 Credentials 07:24:48 26 Discord Slack Nodes 08:18:41 27 Executions History 09:19:06 28 Encrypting Credentials 09:31:44 29 GitHub Google Auth 09:47:36 30 Deployment
