A data integration toolset for finance teams that connects proprietary, licensed and public sources to Python, Excel, AI agents and dashboards.
Data engineers at investment firms spend their days wiring the same market and internal feeds into every new tool. The Open Data Platform by OpenBB removes that repetition by consolidating sources once and exposing them to several surfaces at the same time.
The library installs with pip and gives a Python object model where a call for historical equity prices returns something you push straight into a dataframe. Running the openbb-api command starts a FastAPI server over Uvicorn on localhost, which is what every other client connects to.
The platform reaches analysts, quants and agents through several front doors.
- Python environments: quants query the data model directly and convert results to dataframes.
- OpenBB Workspace: the interface where analysts visualise datasets and run AI agents against them.
- MCP servers: expose the same integrations to AI agents over the Model Context Protocol.
- REST APIs: let other applications consume connected sources without the Python package.
- Command line: a separate openbb-cli package brings the platform into the terminal.
It needs Python 3.9 through 3.12, ships under AGPLv3, and adding a backend to Workspace amounts to pointing the connect form at your local server. The documentation is blunt that the data is not necessarily accurate and that trading carries real risk.
Native C++ desktop terminal for financial research, aimed at students, hobbyists and academics working with market data and AI agents.
Fincept Terminal packages financial research into a single native desktop application, written in C++20 with a Qt6 interface and an embedded Python 3.11 runtime for analytics, so there is no Node.js and no browser runtime underneath.
Two editions run on one data core. This repository is the free AGPL-3.0 edition, intended for learning, personal use and academic research, and it ships one release a month because the team's daily work happens on the closed source Enterprise build. The maintainers state the repository stays public, that released work stays released, and that issues and pull requests are still reviewed on the monthly cycle.
The open build covers several desks at once.
- Analytics: DCF, portfolio optimization, VaR and Sharpe, derivatives pricing, fixed income and an 18 module QuantLib suite.
- AI agents: 37 trader, economic and geopolitics agents running on your own key for OpenAI, Anthropic, Gemini, Groq, DeepSeek, OpenRouter or Ollama.
- Data connectors: more than 100 sources including FRED, IMF, World Bank, DBnomics, Polygon, Kraken and Yahoo Finance.
- Trading: crypto and equity feeds, a paper trading engine and 16 broker integrations.
- Automation: a visual node editor, MCP tools and a quant lab for machine learning and factor discovery.
Installers exist for Windows, Debian, Fedora, generic Linux and Apple Silicon macOS. Building from source needs a pinned toolchain of CMake, Ninja, Qt and Python, and the project warns that newer or older versions are unsupported.
