A free ESG stock screener that publishes its losses and methodology

In plain words

JumpstartSignal is a free daily stock screener that filters companies based on ESG criteria and technical signals. It uses a five-stage pipeline testing 54 individual signals and 1,836 combinations through walk-forward validation across multiple time periods. The tool is designed for investors seeking systematic, longer-term approaches rather than theme-chasing. What distinguishes it is full transparency: the methodology is publicly documented, and the maker publishes both successful and unsuccessful stock picks as case studies showing the system's real-world performance.

ESG/SRI filters exclude 10 categories. Honest case studies include both stocks caught early (NVDA at $6, AAPL at $44 in May 2018) AND stocks missed, with losses published. No paywall, no account.

In the maker’s words, at launch

Hey HN, JSS(JumpstartSignal) is a free, ESG-filtered daily stock screener. I built it after some really badly-timed quantum computing stock buys, so I felt I needed to learn more about systematic, longer-horizon approaches and the underlying technicals instead of chasing themes. Three things about it that might be of…

  With a 9-5 job and 2 kids I have finally finished my first MVP2021 · ▲501

  Hello HN crowd. I worked on this project on weekends and evenings. I'm excited I made it into a presentable MVP, and it is so satisfying. I would like to get some honest feedback from this great community. I made https://freeoptionscreener.com/, to scratch a personal itch. I myself trade options as a hobby, and I didn't find a screener that satisfies my need to be able to explore raw options data freely and without preset constraints. So I made this app that allows playing with options market data and extract interesting opportunities. The techs used: - Laravel + Jquery +…

  I built a tool that watches webpages and exposes changes as RSSMar 2026 · sitespy.app · ▲320

  I built Site Spy after missing a visa appointment slot because a government page changed and I didn’t notice for two weeks. It watches webpages for changes and shows the result like a diff. The part I think HN might find interesting is that it can monitor a specific element on a page, not just the whole page, and it can expose changes as RSS feeds. So instead of tracking an entire noisy page, you can watch just a price, a stock status, a headline, or a specific content block. When it changes, you can inspect the diff, browse the snapshot history, or follow the updates in an RSS reader. It’s…

  Hi HN, I’m Ajay Thakur, founder & CEO of Amsflow. Why I built this. Most stock screeners I have used are over complicated, full of nested dropdowns and endless options and force you to remember arcane syntax. I never really got into any screener, so I built one that just works. What this is. Amsflow Global Stock Screener unifies 550 plus financial metrics and approximately 8,000 filters across all major markets in one seamless interface. You can perform natural language AI queries via our Lisa agent (for example, “Find fintech firms with more than 5 B revenue, 20 percent year on year growth,…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
