PromptPerfect – Open-source prompt optimizer for LLMs
Handy prompt refiner, but prompt engineering itself is becoming obsolete with better base models.

LLM-powered vibe coding for frontends is clever; unclear if it's practical or just novelty.
Early adopters interested in AI-driven UI customization and malleable software experiments
Framer AI · Figma + Claude plugins · No-code builders with generative UI
This is mostly an experiment, but I've put a bit of effort making it into a little platform people can play around with.
With the advances of LLMs being able to one shot some frontend code, I thought it would be a fun experiment to have a end-user facing vibe coding app, following the ideas of malleable software.
It allows users to change the full theme and design from a single prompt, but also and more importantly, allowing the end-users to add features such as categorisation or kanban.
Please let me know any feedback, try to break it etc.

Solves an unsolved problem: format incompatibility between Claude, GPT, LLaMA documented by research.
Stack memory learns your preferences across sessions — FastAPI, typed code, SQLite.
Deliberately removes guardrails to study hallucination as creative feature, not bug.
Static scanner catches prompt injections in code before runtime, unlike runtime guards.
LLMs operate pre-built UI components instead of burning tokens regenerating Chart.js every time.
