Open-source alternatives to a Bloomberg-style terminal
A professional terminal is a newsroom, a chat system, a bond desk and a pricing engine sold for a four-figure monthly fee. OpenStock is none of those. It is a free way for an individual to follow listed companies, read a chart, and open the filings.
The slice OpenStock covers
US, Indian, German, Canadian and Australian stock pages, plus crypto and forex. TradingView charts with drawing tools. A watchlist, email price alerts in realtime mode, and a short weekly news summary. For the S&P 500 and Nasdaq-100, public pages link the latest annual and quarterly reports on SEC EDGAR.
The source is public (AGPL-3.0), so a developer can see how a quote moves from the provider to the screen. That is the part a closed terminal will not show you.
The slice it does not cover
No real-time news wire, no messenger, no order routing, no fixed income, no derivatives analytics, no Excel add-in, and no compliance archive. Prices in the signed-in app come from Finnhub on a personal-use plan and can be delayed. Nothing in OpenStock is a bid or an offer.
If your work is trading on behalf of other people, or marking a book to market, you need a vendor that sells a commercial display licence. OpenStock is a personal and educational tool. The public pages deliberately avoid republishing that quote feed.
A reasonable way to use it
Students, self-hosters and retail investors use it to keep a list and read filings without a seat licence. Treat the chart as a chart and the filing as a filing. For a decision that moves money, read the company’s own report and a source you are allowed to rely on.
Questions
Is OpenStock a Bloomberg alternative?
Only for the narrow job of tracking stocks and reading charts and filings at no charge. It is not a substitute for a professional terminal.
Can a company put OpenStock on an office floor?
The code is AGPL-3.0, so you may run it, with the AGPL’s source-sharing duties if you modify it and provide it as a service. The market-data key most people use is a personal-use plan. A business that displays those quotes needs a commercial licence from a data vendor. OpenStock does not grant one.
Where do the public company pages get their facts?
The chart is a TradingView widget. Sector and index membership are static. Filing dates and industry codes are loaded from SEC EDGAR. No quote is rendered on those pages.

Use OpenStock free
Charts, a watchlist and the US filing pages are free. OpenStock is not a broker and this is not investment advice.
