Research and Data
Free Market Data on GitHub | The Open-Source Bloomberg Alternatives
Open-source terminals and data libraries, from OpenBB to SEC filing tools.
In plain English
These repos fetch market data, company filings and exchange prices for free, so your research and your bots have something to work with.
What Should You Know Before Picking a Research and Data Repo?
Every trading system runs on data, and data is where the hidden bills live. A Bloomberg Terminal costs more per year than many people's cars. These repos are the free and open alternatives.
CCXT is the quiet giant: one library that talks to over a hundred crypto exchanges, sitting under most crypto bots you have heard of. 
edgartools makes SEC filings readable in a few lines of Python. 
OpenBB set out to be the open-source Bloomberg, and its story is worth reading before you build on it.
Free data has a catch. Check the source, check how fresh it is, and never trust a single feed with real money. Two sources that agree beat one source you hope is right.
Who this lane is for
- Researchers who want free fundamentals and filings
- Bot builders who need clean exchange data
- Anyone tired of paying for data they only use twice a month
Where to start: edgartools is the friendliest first step if you trade stocks. CCXT if you trade crypto.

Research and Data Repos FAQ
Is there a free Bloomberg Terminal alternative?
OpenBB was built as one, and other open tools here cover filings and exchange data. None matches Bloomberg's breadth, but for an individual trader they cover most real needs.
Where can I get free SEC filing data?
Straight from the SEC's EDGAR system, and edgartools makes it easy to read in Python without wrestling the raw files.
What is CCXT used for?
It gives your code one consistent way to talk to over a hundred crypto exchanges, so you can fetch prices or place orders without learning each exchange's quirks.
