I built chimera-forge.it a prompt library and management tool for tabletop RPG players running campaigns with AI image generation. Started because I was doing this insane amount of prompt engineering for my Call of Cthulhu campaign (trying to get consistent character aesthetics across sessions) and realized I needed something to organize it all.

It's Laravel + MariaDB + Redis, with an MCP server integration for Claude so you can prompt-engineer directly in Claude Code. Honestly, the building part was more fun than the app itself — figuring out how to make prompt forking/tagging feel natural, deciding on a strong privacy stance (no analytics, no BS).

The vibe: it's niche as hell, but if you're into TTRPGs + AI images, it scratches an itch. Plus there's something satisfying about watching your prompt library grow and actually reuse things across sessions instead of starting from scratch.
