Show HN: I built an interactive HN Simulator

Hey HN! Just for fun, I built an interactive Hacker News Simulator.

You can submit text posts and links, just like the real HN. But on HN Simulator, all of the comments are generated by LLMs + generate instantly.

The best way to use it (IMHO) is to submit a text post or a curl-able URL here: https://news.ysimulator.run/submit. You don't need an account to post.

When you do that, various prompts will be built from a library of commenter archetypes, moods, and shapes. The AI commenters will actually respond to your text post and/or submitted link.

I really wanted it to feel real, and I think the project mostly delivers on that. When I was developing it, I kept getting confused between which tab was the "real" HN and which was the simulator, and accidentally submitted some junk to HN. (Sorry dang and team – I did clean up after myself).

The app itself is built with Node + Express + Postgres, and all of the inference runs on Replicate.

Speaking of Replicate, they generously loaded me up with some free credits for the inference – so shoutout to the team there.

The most technically interesting part of the app is how the comments work. You can read more about it here, as well as explore all of the available archetypes, moods, and shapes that get combined into prompts: https://news.ysimulator.run/comments.html

I hope you all have as much fun playing with it as I did making it!

Show HN: Datamorph – A clean JSON ⇄ CSV converter with auto-detect

Hi everyone,

I built a small web tool called Datamorph because I kept running into JSON/CSV converters that either broke with nested data, required login, or added weird formatting.

Datamorph is a minimal, fast, no-login tool that can:

• Convert JSON → CSV and CSV → JSON • Auto-detect structure (arrays, nested objects, mixed data) • Handle uploads or manual text input • Beautify / fix invalid JSON • Give clean, flat CSV output for real-world messy data

It’s built with React + Supabase + serverless functions. Everything runs client-side except file parsing, so nothing is stored.

I know there are many similar tools, but I tried focusing on:

• better handling of nested JSON, • simpler UI, • zero ads / zero login, • instant conversion without waiting.

Would love feedback on edge cases it fails on, or features you think would make this actually useful for devs and analysts.

Live tool: https://datamorphio.vercel.app/

Thanks for checking it out!
