Vibe coding

† Historical“vibe coding”

Also called obituary

What we briefly called just… talking to an AI until the app worked, without really reading the code.

Think of it like

Cooking without measuring — totally fine for a snack, faintly terrifying for a wedding cake.

Example

In 2024, “I vibe-coded a weekend app” meant you prompted your way to something that ran and shipped it.

How it actually works

Filed as history: what people meant in 2024–25, and why it grew up. The term peaked in early 2025, then split — the throwaway-prototype meaning stuck around as a joke, while the actual practice matured into agentic coding with tests, reviews, and specs. The vibes, it turned out, needed guardrails.

For product teams

The 2024 name for prompt-until-it-works prototyping — now matured into agentic coding with guardrails.

For engineers

Prompt-driven codegen without close review; superseded by agent workflows with tests and specs.
