Build an AI chatbot SaaS with Codex and a task SaaS with Claude Code, using Laravel 13, Next.js 16, MySQL & OpenAI API

What you'll learn
⚡ Build 2 complete multi-tenant AI SaaS apps from scratch, using OpenAI Codex and Claude Code as your AI pair programmers
⚡ Understand vibe coding vs. agentic engineering, and choose the right agent, Codex or Claude Code, for any task
⚡ Turn a product idea into a clear PRD with features and acceptance criteria that AI coding agents can follow
⚡ Write AGENTS md and CLAUDE md instruction files so Codex and Claude Code follow your project's rules every time
⚡ Make Codex propose a plan before it writes code, then turn that plan into clean, idiomatic Laravel code step by step
⚡ Feed errors back so the AI fixes its own mistakes, and use Codex to review your code diffs before you commit
⚡ Manage context and subagents to keep AI coding agents accurate on large, multi-file projects
⚡ Build an AI customer support chatbot SaaS where each company trains its own bot on its content with RAG
⚡ Integrate the OpenAI API and embeddings in Laravel 13, test it in Postman, and run AI jobs with Laravel queues
⚡ Build subscription plans, billing, payments and per-plan usage limits for a real multi-tenant SaaS
⚡ Create multi-role authentication with separate Super Admin and Company dashboards and a support ticket system
⚡ Build a decoupled SaaS with a Next.js 16 frontend and a Laravel 13 API backend, connected with Laravel Sanctum
⚡ Create a design system and admin dashboards with Claude, then build them in Next.js with Tailwind CSS
⚡ Build task management features: projects, tasks, task stages, clients, invoices, expenses, coupons and plan requests
⚡ Protect real projects from AI mistakes with database safety rules, manual backups and Git checkpoints

Requirements
❗ Basic PHP and Laravel knowledge (routes, controllers, models, migrations and Blade)
❗ Basic JavaScript. Some React or Next.js experience helps, but isn't required
❗ A Windows, macOS or Linux computer. Installing VS Code, Node.js, MySQL and Composer is covered step by step
❗ A paid ChatGPT plan to use Codex and a paid Claude plan to use Claude Code (the course shows which plan to choose)
❗ An OpenAI API account with a small amount of credit for the AI chatbot features
❗ No previous experience with Codex, Claude Code or AI agents is needed

DescriptionWrite one prompt and your whole app is ready? That's the promise you see everywhere. In real life, it doesn't work. One prompt gives you a demo. A real, advanced application needs a proven workflow and a solid structure, and that's exactly what this course gives you.

InClaude Code & OpenAI Codex: Build 2 Real AI SaaS Apps, you'll learnagentic engineering: you plan the work, the AI coding agent builds it, and you stay in control. No tool tours and no toy demos. You'll buildtwo complete, multi-tenant SaaS applications, step by step, with the two leading AI coding agents.

Project 1: Multi-Tenant AI Customer Support SaaS (built with OpenAI Codex)
UsingLaravel 13, MySQL and the OpenAI API, you'll build a platform where every company trains its own AI support chatbot on its own content

✨ Multi-authentication with separate Super Admin and Company dashboards

✨ Bot training withRAG (Retrieval-Augmented Generation) and OpenAI embeddings

✨ Bot conversations and a complete support ticket system

✨ Subscription plans, billing, payments and per-plan usage limits

✨ Laravel queues for AI responses and knowledge ingestion

Project 2: Task Management SaaS for Small Business (built with Claude Code)
This time the architecture levels up: aNext.js 16 frontend with aLaravel 13 API backend and MySQL. You'll

✨ Create a complete design system and Admin and Company dashboards with Claude

✨ Build multi-authentication, companies, subscription plans, coupons and plan requests

✨ Build the company workspace: clients, projects, task stages, tasks, invoices and expenses

✨ Connect a separate frontend and backend cleanly, the setup most developers struggle with

The workflow you'll use on every project
Before any code is written, you'll learn to plan like a professional. You'll turn an idea into aPRD, writeAGENTS md andCLAUDE md instruction files, make the agent propose a plan first, feed errors back so it fixes its own mistakes, review AI-generated code diffs, and manage context and subagents on large projects.

You'll also learn the safety habits that protect real projects: database protection rules for AI agents, backups, and Git checkpoints.

Why this course is different
✨Two agents, one course. You build with both OpenAI Codex and Claude Code, so you learn exactly when to use each one.

✨Real SaaS, not toy apps. Multi-tenancy, plans, billing, RAG chatbots and dashboards: the features real products need.

✨Source code at every milestone. Each major step has its own GitHub checkpoint, so you can compare your code or catch up anytime.

✨An experienced instructor. I've been programming for over 12 years and have taught more than 100,000 students on Udemy.

By the end, you'll have two real SaaS products in your portfolio, a workflow you can repeat on every project, and the confidence to build the applications you've been dreaming about.

Watch the free preview lectures, then enroll, and let's build your first AI SaaS together.

Who this course is for
⭐ Laravel and PHP developers who want to build complete SaaS apps faster with OpenAI Codex and Claude Code
⭐ Developers who tried vibe coding but got stuck when the project grew, and want a reliable, professional workflow
⭐ Freelancers and agency developers who want to deliver client projects faster with AI, without messy or unsafe code
⭐ Aspiring SaaS founders who want to turn an idea into a working multi-tenant SaaS with plans, billing and dashboards
⭐ Full-stack developers who want to learn a Laravel API + Next.js 16 architecture and build AI features like RAG chatbots
