About OpenBB
Open-source investment research platform that connects many data providers to one interface, with AI agents in its workspace.
OpenBB started as an open-source investment terminal and now offers an open-source platform for developers and a workspace product for research teams. It connects to many data providers, some free and some needing your own API keys, and presents their data through one interface.
Developers use the open-source platform in Python to pull and combine data for their own analysis. The workspace adds dashboards and AI agents that answer questions using the connected data, which lets a team build its own research setup.
Because the data comes from the providers you connect, check each provider's coverage and terms. The open-source code is free to use; the hosted workspace has its own plans. Its code is public on GitHub, so you can read how a data source is used before relying on it.
