What it does
An open data platform that consolidates proprietary, licensed and public financial sources behind one interface, then exposes them to Python for quants, to Workspace and Excel for analysts, to MCP servers for AI agents and to REST for everything else. It is plumbing rather than analysis, and it is emphatically not investment advice: figures inherit the accuracy, latency and redistribution terms of whichever provider they came from. AGPL-3.0.
Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.

OpenBB FAQ
- Is OpenBB free?
- OpenBB itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.
- Do I need to install anything or write code to use OpenBB?
- It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
- Does OpenBB work on a phone?
- No. It needs a computer.
- Can I use OpenBB commercially?
- The project does not state a clear licence, so commercial use cannot be confirmed here. Check the official page or ask the author before using it at work.
