What is vibe-budget?

vibe-budget is a CLI tool that estimates the real cost of building AI coding projects before you start spending tokens.

Describe your project in plain English or Spanish — vibe-budget detects the tasks involved, estimates token usage per task, fetches live prices from 85+ models via OpenRouter, and recommends the best model for your budget.

Know the cost before you code.

The problem

You open Cursor, describe your project, and start vibing.
Three hours later — $47 gone. On a landing page.

Most developers have no idea how many tokens a project actually costs until after the fact. A task that costs $0.01 with Gemini Flash costs $5.80 with Claude Opus. vibe-budget fixes this.

What it does

Detects technical tasks from natural language descriptions
Estimates token count per task — input and output separately
Fetches real-time prices from OpenRouter across 85+ models
Recommends the best model per task based on quality/price ratio
Scans existing codebases to estimate refactoring or extension costs
Compares cheapest, best value, and premium options side by side

No opinions. No "you should use X". Just the numbers — you decide.
