PromptVersionControl: LLM Experiment Tracker
Git-like version control for AI prompts with A/B testing, cost tracking, and performance comparison — for teams shipping AI features.
The Problem
AI teams constantly tweak prompts to improve outputs, but there's no systematic way to track which prompt versions produced better results, what changed between iterations, or how much each prompt costs. Engineers end up with messy spreadsheets, lost experiments, and no data-driven way to optimize.
Target Audience
Solo founders and small engineering teams (2-5 people) building AI-powered features in SaaS apps, who use LLMs daily and want to ship better AI without wasting tokens.
Why Now?
Every vibe coder is now shipping AI features in their apps. The prompt iteration cycle is painful and ad-hoc, and there's a clear appetite for developer-friendly, minimalist tools.
What's Missing
Existing prompt management tools are enterprise-focused and overengineered. Vibe coders need something as simple as Git but for prompts — lightweight, CLI-friendly, integrated with their workflow.
