24 alternatives to I built a tool for viral Reddit posts after analyzing 562 subreddits
It took me six months to analyze 562 subreddits. I systematically parsed titles, post bodies, and user interactions to identify statistically significant patterns and evaluate if it was possible to create a model that could predict the likelihood of a post going viral based on specific features. The key findings were unexpected: while the title of a post has a direct correlation with engagement, there is another highly influential factor I initially overlooked, timing. The optimal time to post on Reddit, in terms of engagement, can significantly vary based on geographic distribution. The…

We built Valohai LLM for tracking and comparing LLM evaluation results. Whether your evals live in notebooks and spreadsheets, or you're using an observability tool that wasn't built for comparison, this gives you a purpose-built eval comparison dashboard. Run evals with a Python library (pip install valohai-llm), results stream in, and you can compare up to 6 configurations side by side. Group by any dimension (model, category, difficulty) to see where each model excels. It doesn't do tracing or production observability, for now just eval tracking and comparison. What's cool is that you can…

Linkeddit▲618The tool actually hit Product Hunt #1 back in February. Since then I’ve added a bunch more on top of the original version. Now you just describe the intent or goal for the leads you want, and it searches based on keywords and a bunch of other signals to surface the best ones for you. I also added a Reddit-powered content writer. Basically, you pick a topic or category, and it pulls the top posts from Reddit, analyzes what made them go viral, and helps you write content using the same patterns. Reddit is super underrated for content. If something blows up there, it almost always spreads to…

Hey HN, We analyzed 4,010,957 Hacker News submissions to find what actually makes posts perform well. Key findings: - 93.2% of posts never hit 50 points - Top 1% starts at 270 points - Certain keywords boost engagement by 1000%+ Built a free tool that scores your launch title and predicts viral potential: [link] The entire 4M post dataset is available as a single 700MB .mv2 file if you want to run your own analysis.

Hey HN community, I built a tool that helps optimize your post for hitting the first page of Show HN. How it works: I used a Hugging Face dataset of all Hacker News posts from the past 3 years and trained a model that predicts how successful your post might be. There's still a lot of randomness on HN, so nothing is guaranteed, but the tool helps optimize your post for higher odds. A couple of interesting findings: - GitHub repo links work x3 better than regular domains - Open-source tools have a steady virality rate (13.9% - one of the highest) - "I built" outperforms "We built" - Using…

I built a system that monitors ~200,000 news RSS feeds in near real-time and clusters related articles to show how stories spread across the web. It uses Snowflake’s Arctic model for embeddings and HNSW for fast similarity search. Each “story cluster” shows who published first, how fast it propagated, and how the narrative evolved as more outlets picked it up. Would love feedback on the architecture, scaling approach, and any ways to make the clusters more accurate or useful. Live demo: https://yandori.io/news-flow/

Scriptmine▲86I built this for myself. I make videos, and my biggest bottleneck is figuring out what to say to my audience without staring at a blank page. So I built Scriptmine: a tool that listens to Reddit conversations in my niche, finds high-signal topics, and turns them into scripts. How it works: - Track subreddits and discussions relevant to a niche - Rank topics by engagement/momentum - Generate a hook/body/CTA draft in a chosen voice/format

I built an archiver that tracked every HN item for 27 days (Dec 3-30, 2025) and captured 72k temporal snapshots to see how posts gain and lose attention. Key findings: - Early velocity (points/hour in first 2 hours) predicts final score with ρ=0.82. A simple classifier achieves 98.4% precision for viral prediction. - No Matthew effect: high-scoring posts don't get more upvotes per hour than low-scoring ones (ρ=-0.04). HN's gravity penalty actually works. - Yet extreme inequality persists: Gini=0.89, meaning bottom 80% of posts get <10% of total upvotes. Inequality without cumulative…

Hey friends! I’d like to introduce my latest product, Flashpost, a post scheduling tool for Reddit. The free tier includes 5 free posts per month so you can give the product a try. It is my first paid product as I try to make it as a solo indie dev! The goal is to offer a simple tool for creators to promote their projects on Reddit without breaking the bank for a single distribution channel. Now for the behind the scenes details. ## The Backstory When I launched my first project TechStackLeads on Reddit, the response was remarkable. My post received 700k impressions, resulting in 20k…

After nearly a year of development, I've launched Problem Spotter - a tool that helps you discover relevant Reddit communities and track their growth patterns. Key features: - Search across subreddits by topic/keyword - Monthly subscriber growth tracking and trends - Audience overlap analysis Built this because I was manually hunting through Reddit for market research and community validation. The existing tools either didn't have good search or lacked growth data. Would love feedback from the HN community - especially if you use Reddit for research or community building. Link:…

I've tracked the top 3000 subscribed (and some subreddits that I visit frequently) subreddit's active user over time, so you know when to post to get the most feedback! I come from a nodejs background, and this is the first time coding with Go, so the structures might not be standard. But feel free to give me any feedbacks!

I was lucky enough to have my site trending on Friday (https://news.ycombinator.com/item?id=25872922). It’s an icon site that lists open source icons. I wanted to share some stats on the results after 3 days. Worth noting was that I submitted it on a Friday morning (at which point I went for a walk and a coffee; eek). - 24,997 page views. I (embarrassingly) didn’t have GA set up when I first submitted it, so this is probably missing a few hundred page views - 21 “feedback” emails (half of which were spam). I assume such a high percentage of these were spam because my Feedback…

I wanted to find a product idea to build. "Build things people want," right? So I thought, why not literally find people saying what they want? I wrote a script to collect thousands of Reddit posts where people are looking for a solution or complaining about a problem. Then I used GPT to filter out the noise and score each one based on how viable the idea seemed. Threw together a simple search interface so anyone can explore them. I was planning to build a more advanced paid version of this, but figured I'd share the raw version first to see if it's actually useful to anyone.

Hello HN! About 1.5 years ago we published an idea on how to improve the Hacker News ranking algorithm (https://felx.me/2021/08/29/improving-the-hacker-news-ranking...). The main idea was to counteract the rank-upvotes feedback loop by using attention as negative feedback. We received very valuable input from the HN community (https://news.ycombinator.com/item?id=28391659), and have since come up with something that we think could be a real contribution: the upvoteRate metric. upvoteRate is an estimate of how much more or less likely users are to…
