# 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.
