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.

From the sources
Prom turns prompts into shareable software we call drops. Type an idea, it becomes real, share the link. Done. No commitment, no maintenance, no "where is this going" talk. Just software that exists because you had an idea at 1am. But Prom isn't just a builder. It's a creative platform where you discover and remix what other people are making. Browse trending drops, fork something cool, make it your own. Software is becoming content and Prom is where you make it.
Prom.dev is the internet

PrompTessor2025 · promptessor.com · ▲125After countless hours of solo coding, designing, and iterating, I’m both excited and nervous to share my first-ever product: PrompTessor — now live. As someone who constantly experiments with AI tools like ChatGPT and Midjourney, I often found myself stuck in a loop of trial-and-error. The issue wasn’t always the AI — it was often the prompt itself. That observation became the starting point for PrompTessor. This tool doesn’t just optimize your prompt — it analyzes it. It gives you: - A prompt score - A breakdown of strengths and weaknesses - A fully optimized version of your prompt - And…

Hey HN! While writing prompts for a few projects recently, a couple of friends and I realised that writing prompts today is like writing code in a txt file - it sucks and there is no tooling to help you. So we decided to hack on a tool to help you fix this - https://optimist.varied.ai/ It is literally a hack rn but we already find it useful for writing prompts. That said we'd love to talk to folks who are writing serious prompts everyday and see how the product can be better. Also the only reason the waitlist is there, is running this is super expensive like $100/day for…
