The VIBE Score: 8 Dimensions of Software Quality

A single quality number hides more than it reveals. The VIBE Score framework disaggregates software quality into eight measurable dimensions, each scored independently and weighted by risk impact. The result is a quality signal that is both comprehensive and actionable.

The Eight Dimensions

V — Velocity

How fast and reliably does the team ship? Deployment frequency, lead time for changes, CI/CD maturity, and feature flag usage.

I — Intelligence

How well is AI integrated? Prompt injection prevention, output validation, model version pinning, and fallback strategies.

B — Build Quality

How healthy is the codebase? Test coverage, type safety, dependency hygiene, and technical debt ratio.

E — Experience

How good is the user experience? Core Web Vitals, WCAG accessibility, responsive design, and error recovery patterns.

Security

How hardened is the attack surface? CSP headers, input validation, authentication patterns, and dependency vulnerabilities.

Scalability

How ready is it for growth? Horizontal scaling, database optimization, CDN strategy, and cache architecture.

Reliability

How resilient is it? Error budgets, monitoring coverage, alerting, disaster recovery, and graceful degradation.

Maintainability

How sustainable is it long-term? Documentation coverage, onboarding time, modular architecture, and upgrade path clarity.

Scoring Methodology

Each dimension is scored 0–100 using a combination of automated analysis and structured expert review. Dimensions are weighted by importance, with Security and Intelligence carrying higher weights due to the novel risks introduced by AI-generated code.

Frequently Asked Questions

How is the VIBE Score calculated?

Each of the 8 dimensions (Velocity, Intelligence, Build Quality, Experience, Security, Scalability, Reliability, Maintainability) is scored 0-100 using a combination of automated analysis and expert review. Dimensions are weighted by importance and combined into a weighted average.

What does each letter in VIBE stand for?

V stands for Velocity (speed to ship), I for Intelligence (AI integration quality), B for Build Quality (code health and testing), and E for Experience (UX, accessibility, and performance). The remaining four dimensions — Security, Scalability, Reliability, and Maintainability — extend the framework.

Can an app improve its VIBE Score?

Absolutely. The VIBE Score is designed to be actionable, not punitive. Each dimension comes with specific criteria and improvement recommendations. Many founders improve their score by 20-30 points within weeks of their initial audit.

Is the VIBE Score comparable across different types of apps?

Yes. The dimensions are technology-agnostic and apply whether your app is built with React, Flutter, Rails, or pure AI generation. The criteria within each dimension adjust contextually, but the scoring methodology remains consistent.
