# Prompt version control

> Git-for-prompts that non-engineers can use, a small focused tool that every AI team eventually wants.

**Sector**: [AI & Machine Learning](https://signals.gitdealflow.com/niche-down/ai-ml)  
**Build cost**: Month-long build  
**Deal velocity**: Steady, one deal per month

## Why now

Prompts live in three places (code, prompt files, vendor consoles) and drift constantly. The tool that gives PMs a diff view wins the workflow.

## What the signal looks like

Repos with a CLI + dashboard combo, integration test directories for popular frameworks, and a 'compare two prompt versions' demo in the README.

## Public examples

*Public projects + categories only, we never name founders tracked inside the paid product.*

- PromptLayer-style hosted prompt registries
- Vellum-shaped prompt management platforms
- Open-source Git-for-prompts CLIs

## What this displaces

A Notion page maintained by one tired prompt engineer.

## Our build-vs-invest call

Two-product company: free CLI + paid hosted dashboard with eval integration. The moat is in the eval link, versions without evals are useless. Watch for repos that add eval integration in the same commit as multi-user access.

## Frequently asked

### Is this a feature of the observability tool?

Possibly, and the observability tools will try. But the non-engineer surface is a different product.

### Who's the buyer?

AI PMs and applied AI leads, $200-500 per seat per month.

### What's the wedge?

Slack + GitHub integration. The PM lives in Slack and reviews diffs in GitHub. Match that.
