PromptVault - Expert-engineered AI prompts that actually works

by•
Most AI prompts are written once, tested never, and shared everywhere. PromptVault is different — every prompt is battle-tested across real projects before it's sold. We sell structured prompt systems for: 🛠 Developer Tools — Claude Code templates, Cursor rules for Next.js, API design review frameworks, DevOps & Terraform prompt packs 🎮 Game Development — Godot 4 GDScript generation system, Unity C# patterns, game narrative design, game design toolkits 📣 Marketing — Cold email templates

ey PH 👋 I'm the founder of PromptVault. Built this in 48 hours after getting frustrated with how bad most "AI prompt" resources are — vague, untested, and written by people who don't actually use the tools. Every prompt in the store comes from real work: The Claude Code CLAUDE.md template? Built across 10+ production projects. The Godot 4 system? Written by someone who has shipped Godot games. The cold email pack? 2,000+ emails worth of testing. For launch day, use code PRODUCTHUNT for 20% off anything. Happy to answer any questions about the products, the tech stack (Next.js + Stripe + Resend, all serverless), or how I approached prompt engineering for each niche. What AI tools are you using where prompts feel like the bottleneck? --- Launch day checklist: - Schedule for Thursday midnight PST (launches Friday morning — peak traffic day) - Post in the comments every hour for the first 4 hours responding to every question - Share the PH link on your Twitter thread - Ask 5-10 friends to upvote first thing in the morning — early momentum is everything on PH

love that you actually put these prompts through real projects before selling them, the Claude Code templates especially feel like they were actually used to ship something. refreshing compared to the usual prompt packs full of untested filler.

How do you actually validate that a prompt is "battle-tested" before listing it, and is that process something the prompt author handles themselves or does your team run it?
