About This Launch
PromptMafia is a free directory of AI prompts that people actually used to ship something. Prompts come from founders, designers and developers who shared them publicly, and each one is credited to its original author with a link back to the source post. PromptMafia shows the result next to the prompt, so you can see what a prompt produced before you copy it.
The library covers Claude and Opus video prompts, Claude Code + Remotion launch videos, landing page and design system prompts, and growth and strategy prompts. Free, no signup.
Why I Built This
Most prompt lists are generic or untested. I wanted one place to see real prompts founders actually used, with the result next to the prompt and credit to the original author.
