Hi Product Hunt People 👋 Stefan here.
Every stock site hands you a verdict and keeps the reasoning. "78/100" — measured how, from which filing, when? The few that show their work want €30 a month.
So I built my own screener in the evenings. It was only ever meant for me and my own long/swing trades, and it got a bit out of hand: 163 rules now, running on 8,562 stocks, ETFs, funds and indices. A score is just the rules that passed. Click one and you get the formula, the source and when it ran.
Most tools also stop at good company / bad company. That's one of three questions: how solid the company is, what today's price does to that, and whether the thing is actually growing. Those are three separate scores here, and they disagree with each other more often than you'd expect — plenty of good companies are priced like perfect ones.
Nobody can judge a company in ten seconds, and a decision you can defend rests on a lot of evidence, not one ratio and a gut feeling. So the mechanical part runs for you, and what's left is the part that needs your own judgement.
Two things I'd defend: if the data for a check is missing, it stays missing and the company stays unrated — a fake 0 looks exactly like a bad company. And the scores are backtested against their own history, bad results included. One of my own scores predicted close to nothing, so I pulled it out of the verdict.
I'm sharing it now because there's no reason not to. Everything is free with no restrictions: no paywall, no locked rules, no signup to look around. Sponsors and donations keep it running, and if a paid tier ever shows up it'll be for heavy data access, never for hiding the reasoning. It's not advice either, and it will never tell you what to buy.
Open something you actually own and read the rules behind its score: which one would you bin, and what would you put there instead? Right now the "community" is me and a handful of friends who tell me when something looks off, so an answer here genuinely decides what I build next.
