Main marketing page: https://prompt-vc.vercel.app Marketplace: https://marketplace.visualstudio.com/items?itemName=SehmimHaque.promptvc-vscode

Git for prompts.

PromptVC is an LLM-agnostic, local-first prompt tracker and prompt version control system for AI-assisted development.

It lets you track every prompt, diff prompt evolution, and see exactly what code each prompt changed - enabling reproducible prompt-based programming and disciplined vibe coding workflows.

What it does

PromptVC shows you exactly what each prompt changed in your code.

• Prompt -> Files changed -> Line diffs -> Session context
• Git-style review for prompts
• Works with any LLM (Codex today, Claude and Gemini soon)

Prompts become first-class engineering artifacts.

Demo

Each prompt is tracked, diffed, and reviewable - just like code.

LLM Support

• Codex - supported today
• Claude - coming soon
• Gemini - coming soon
• Designed to work with any LLM via hooks

PromptVC is intentionally LLM-agnostic.

Why PromptVC Exists

AI behavior changes when prompts drift.

Without prompt tracking:

• Bugs are hard to reproduce
• Prompt regressions are invisible
• Prompt intent is lost
• Team collaboration breaks

PromptVC makes prompt evolution visible, reviewable, and auditable.

Core Capabilities

• Prompt tracking per session
• Prompt version control with Git-style diffs
• Per-prompt file and line impact
• Unified and split diff views
• Prompt review workflow (mark, hide, flag)
• Local-first storage
• CLI + VS Code UI

Prompt-by-Prompt Code Impact

Each prompt is linked to:

• Files changed
• Line diffs
• Session context

You can answer:

"What did this prompt actually change?"

instantly.

Built for Prompt-Based Programming

PromptVC enables:

• Prompt-based programming
• Prompt auditing
• Prompt regression detection
• Vibe coding with reproducibility
• Prompt workflow discipline

Coming Soon - Prompt Tracker Platform

Team collaboration features:
