Show HN: Don't share code. Share the prompt
jacomoRodriguez Tuesday, March 10, 2026Hey HN, I'm Mario. I recently talked to a colleague about AI, agents and how software development will change in the future. We were wondering why we should even share code anymore when AI agents are already really good at implementing software, just through prompts. Why can't everyone get customized software with prompts?
"Share the prompt, not the code."
Well, I thought, great idea, let's do that. That's why I built Open Prompt Hub: https://openprompthub.io.
Think GitHub just for prompts.
The idea is simple: Users can upload prompts that can then be used by you and your AI tools to generate a script, app, or web service (or prime their agent for a certain task): Just past it into your agent or ide and watch it build for you. If the prompt does not 100% covers your usecase, fork it, tweak it, et voila: tailor-made software ready to use!
The prompts are simple markdown files with a frontematter block for meta information. (The spec can be found here: https://openprompthub.io/docs) They versioned, have information on which AI models build it successfuly and have instructions on how the AI agent can test the resulting software.
Users can mention with which models they have successfully or unsuccessfully executed a prompt (builds or fail). This helps in assessing whether a prompt provides reliable output or not.
Want to create a open prompt file? Here is the prompt for it which will guide you through: https://openprompthub.io/open-prompt-hub/create-open-prompt
Security! Always a topic when dealing with AI and prompts? I've added several security checks that look at every prompt for injections and malicious behavior. Statistical analysis as well as two checks against LLMs for behaviour classification and prompt injection detection.
It's an MVP for now. But all the mentioned features are already included.
If this sounds good, let me know. Try a prompt, fork it, or tell me what you'd change in the spec or security scanner. I'm really curious about what would make you trust and reuse prompts. Or if you like the general idea...
