Open Vibe
Open Vibe is a free, open-source tool that turns Claude Code or another compatible agent into a guided SaaS-building assistant.
Overview
Open Vibe is a free, open-source learning tool for people building SaaS apps with AI coding agents. It turns Claude Code, or another capable agent, into a guided assistant that teaches the systems behind a production-ready app while you work on your own idea.
The site presents Open Vibe as a terminal-based workflow with no signup required. You paste an install prompt into your agent, then build alongside step-by-step instructions, live diagrams, and explanations that help you understand how the app is wired together.
What Open Vibe includes
Agent-agnostic course pack
The course pack is plain Markdown, so the instructions can run in agents that can read files and execute tools.
In-agent instruction
Open Vibe teaches by embedding guidance, skills, and diagrams directly in the agent session while you build.
Interactive system diagrams
Live diagrams show how requests move through browser, server, and database layers on your running app.
Structured learning phases
The product organizes learning into phases and modules, including basics of web apps and building on the Open SaaS template.
Local-first workflow
Open Vibe positions itself as a local workflow, so your code stays on your machine while you work.
When Open Vibe fits
Learning while shipping a SaaS
Use it when you want to build a SaaS app with an AI agent while also learning how the browser, server, and database pieces fit together.
Starting from web app basics
Use it if you are new to web apps and want a guided path from setup through basic full-stack concepts.
Extending a SaaS starter
Use it if you already know the basics and want to build on the Open SaaS starter template, which includes auth, payments, admin, email, and AI.
Interactive agent-led learning
Use it when you want explanations that appear inside your agent session instead of switching to videos or static course material.
Local terminal workflow
Use it if you prefer a local, no-signup workflow and want to keep working in your own terminal environment.
