Description
𝐏𝐫𝐨𝐦𝐩𝐭𝐅𝐨𝐫𝐠𝐞 is an open-source prompt engineering workbench built by developer insaaniManav, with a Go-based API backend. The project gives prompt engineers a workspace to draft prompts, run them against multiple models, and compare outputs without wiring up custom evaluation scripts for every change. It addresses the workflow gap between writing a prompt in a notebook and shipping a tested version to production.
Key Capabilities:
✓ Prompt drafting and iteration interface with side-by-side output comparison
✓ Systematic prompt evaluation across multiple LLM providers and model versions
✓ Prompt versioning with diff tracking between iterations
✓ Test case management for regression checks on prompt changes
✓ Analysis tools for scoring response quality across runs
✓ Self-hostable deployment via Go API backend
✓ Open source under a permissive license
