Hi everyone, I'm Alex, I built this a tool to make it easier to research company financials. Company financials have always been public — they're in SEC filings. But actually working with that data meant either expensive professional tools or a lot of manual digging. I wanted something in between. Open Terminal pulls structured financials for ~10,000 US public companies from SEC filings. You can: • Chart any reported metric (revenue, margins, R&D spend) across companies and time • Plot your watchlist and aggregate as portfolio performance • Read news filtered by whether it's actually about your ticker, with sentiment scoring • Ask AI question in plain English and get a chart back • Or write SQL directly against the whole database It runs in the browser, and the code is on GitHub if you want to self-host. Backend is ClickHouse, Python flask + gunicorn, and DuckDB. What it doesn't do yet: international stocks, intraday prices. I launched an early version on Hacker News and my server fell over within the hour, which taught me more about load testing than any blog post ever did. It's been rebuilt since. I'll be around all day — happy to answer anything, including unflattering questions about the data pipeline.
