1. 1
   PromptForge▲474

   PromptForge: Open-source AI prompt engineering workbench with systematic evaluation I built PromptForge after getting frustrated with the manual trial-and-error approach to prompt engineering. Most tools are just text editors, but I wanted something that brings software engineering discipline to prompt development. Key technical features: - AI-assisted prompt generation (stop starting from scratch) - Systematic evaluation engine that auto-generates test suites - Multi-model support (Claude, GPT-4, Azure OpenAI) - Go backend with SQLite for performance and simplicity - One-line Docker…

   PrompTessor▲125

   After countless hours of solo coding, designing, and iterating, I’m both excited and nervous to share my first-ever product: PrompTessor — now live. As someone who constantly experiments with AI tools like ChatGPT and Midjourney, I often found myself stuck in a loop of trial-and-error. The issue wasn’t always the AI — it was often the prompt itself. That observation became the starting point for PrompTessor. This tool doesn’t just optimize your prompt — it analyzes it. It gives you: - A prompt score - A breakdown of strengths and weaknesses - A fully optimized version of your prompt - And…

    Prompt Inspector – A browser-like inspect tool for prompts▲23

    I was working on a project that involved indexing GitHub repos that used really long prompts. Iterating over each section and figuring out which parts of the prompt led to which parts of the output was a quite painful. As a frontend dev, I kept thinking it would be nice if I could just 'inspect element' on particular sections of the prompt. So I built this prompt debugger with visual mapping that shows exactly which parts generate which outputs. Now that context windows are getting huge, working with massive prompts should not be as difficult. Planning to open source this soon, but I'd love…
