PromptAudit: LLM API Cost Analyzer
Real-time dashboard that tracks token usage, costs, and performance across all LLM API calls (OpenAI, Anthropic, Groq) to catch runaway spending before it happens.
The Problem
AI app developers using multiple LLM providers have no unified visibility into which API calls are draining their budget. A single misconfigured prompt or model selection can cost hundreds/month without detection, and existing billing dashboards from providers are slow, fragmented, and don't cross-compare cost-per-quality metrics.
Target Audience
Vibe coders and small teams building AI features into apps using Cursor/Lovable who integrate LLM APIs and need cost control without complex DevOps setup.
Why Now?
Token prices are dropping (making volume/waste more visible), multi-model strategies are standard (Cursor users flip between OpenAI/Claude constantly), and cost consciousness is peak after AI hype bubble.
What's Missing
Existing solutions are either vendor-locked (OpenAI's own dashboard), overkill for solo devs (Langsmith), or require code changes (LiteLLM wrapping). No lightweight cross-provider tracker with alerts designed for vibe coders.
