Live Demo: SDD vs Vibe Coding in 10 Minutes

Live Demo: SDD vs Vibe Coding in 10 Minutes This is the demo that makes the difference tangible. Two approaches, same feature, same AI. The contrast speaks for itself. Use this for conference talks, team workshops, or to convince a skeptical colleague that the spec-first approach is worth the two minutes it takes. Setup (before the demo) Have a project with Planu installed in Claude Code Have a simple feature idea ready: "add dark mode toggle" Ideally have two terminal windows side by side Part 1: The Vibe Coding Approach (3 min) Say: "This is how most people use AI coding tools today." Open Claude Code in a project without Planu Type: "Add a dark mode toggle to the settings page" Watch Claude write code Ask the audience: "How do you know this is correct?
