PromptVault
Expert-engineered AI prompts that actually works
Most AI prompts are written once, tested never, and shared everywhere. PromptVault is different โ every prompt is battle-tested across real projects before it's sold. We sell structured prompt systems for: ๐ Developer Tools โ Claude Code templates, Cursor rules for Next.js, API design review frameworks, DevOps & Terraform prompt packs ๐ฎ Game Development โ Godot 4 GDScript generation system, Unity C# patterns, game narrative design, game design toolkits ๐ฃ Marketing โ Cold email templates

I'm the founder of PromptVault. Built this in 48 hours after getting frustrated with how bad most "AI prompt" resources are โ 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?
