Prom.dev – Prompts that simulate Hacker News (and a tool to share them)
We’re Heather and Matt, and we want to invite you to Prom. Prom is a simple place to share the prompts you’re proud of and discover ones other people actually use. The idea came out of a lightweight internal library we hacked together for our team earlier this year. Before that, we had “good prompts” on Slack or Google Docs. We wanted a dedicated place for prompts, and somewhere people can post what’s working for them, compare approaches and models, and see what “good” looks like in the wild. The tech is, well, nothing fancy, but intentionally lightweight. Flask backend, Bootstrap frontend.…
In plain words
Prom.dev is a platform for sharing and discovering AI prompts that people actively use. Created by Heather and Matt, it provides a dedicated space where users can post prompts, compare different approaches and models, and see real-world examples of effective prompting. The tool supports both private and public prompts with direct integration into Cursor for seamless workflow. Built with a lightweight Flask and Bootstrap stack, it lets users learn from what actually works in practice rather than scattered notes across Slack or documents.

In the maker’s words, at launch
We’re Heather and Matt, and we want to invite you to Prom. Prom is a simple place to share the prompts you’re proud of and discover ones other people actually use. The idea came out of a lightweight internal library we hacked together for our team earlier this year. Before that, we had “good prompts” on Slack or Google Docs. We wanted a dedicated place for prompts, and somewhere people can post what’s working for them, compare approaches and models, and see what “good” looks like in the wild. The tech is, well, nothing fancy, but intentionally lightweight. Flask backend, Bootstrap frontend. You can keep prompts private or make them public, and open them directly in Cursor with a deeplink if that’s your workflow. Right now it’s early and pretty minimal. We’re thinking about adding things like version history, a prompt improver, and maybe an MCP server, but the part we care most about right now is the community. We think it would be cool to see people sharing weird experiments and genuinely useful prompts. If you try it, we’d love to know what you think, what kind of prompts you might build, and hear what would make this a better place to post and browse prompts. Enjoy Prom!
