Why PromptForge?

Most prompt tools are glorified text editors. PromptForge brings engineering discipline to prompt development:

• ✨ Smart Prompt Generation - AI-powered prompt crafting with intelligent suggestions
• 🔍 Advanced Prompt Analysis - Get optimization feedback before you even test
• 🧪 Systematic Evaluation - Generate comprehensive test suites automatically
• 📊 Performance Analytics - Track what works across different scenarios
• 📚 Version Control - Never lose a working prompt again

Quick Start

One-line Docker setup:

docker run -d -p 8080:8080 -e ANTHROPIC_API_KEY="your-key" ghcr.io/insaanimanav/prompt-forge:main

Or clone and run:

git clone https://github.com/insaanimanav/promptforge.git
cd promptforge && ./start.sh

Open http://localhost:8080 and start crafting better prompts.
