OpenBB — AI-powered analytics workspace built for investment teams

What is OpenBB?

What it is

OpenBB is an open-source data platform for investment professionals, built as the Open Data Platform (ODP) and extended by the OpenBB Workspace UI. It lives in the quantitative finance and AI agent ecosystem, integrating equity, crypto, derivatives, fixed income, economics, and options data from proprietary, licensed, and public sources.

It solves the problem of fragmented data access by providing a unified interface to ingest and expose financial data across multiple consumer surfaces—Python environments, Excel, REST APIs, and AI agents—without requiring separate integrations for each. This eliminates redundant data pipeline development and ensures consistency between analyst dashboards, backtested models, and AI copilots.

Key capabilities

  • Fetch and normalize historical price data for equities, crypto, and options using a single Python API (obb.equity.price.historical("AAPL")).
  • Expose data via a FastAPI backend (openbb-api) running on 127.0.0.1:6900, supporting REST consumption.
  • Connect to OpenBB Workspace via a GUI to visualize datasets and integrate AI agents using the same backend.
  • Support Python versions 3.9.21–3.12 for local analysis and scripting.
  • Install via PyPI (pip install openbb) or CLI (pip install openbb-cli) for programmatic or command-line use.
  • Integrate third-party data providers through modular extensions documented in the OpenBB repository.
  • Run in Dev Containers for reproducible environments using VS Code Remote Containers.

Who uses it and how

  • Quantitative researchers use the Python SDK to build backtested strategies and feed ML models with standardized financial time series.
  • Investment analysts embed the OpenBB Workspace UI in their workflow to explore data visually and share findings with team members.
  • AI agent developers connect the FastAPI backend to LLMs or autonomous agents to enable natural-language querying of financial data.
  • Data engineers deploy the backend in internal networks to serve as a centralized data layer for downstream analytics tools.

Getting started

Install with pip install openbb or pip install openbb-cli, then start the API server with openbb-api. Deploy OpenBB Workspace by signing in at https://pro.openbb.co/ and connecting the local backend via the Apps tab.

When to use it — and when not to

Use OpenBB when you need a free, open-source data pipeline for financial analytics and AI agents, especially where integration flexibility across Python, Excel, and APIs matters. Avoid it if you require out-of-the-box managed infrastructure—self-hosing demands a FastAPI server, database, and potentially SMTP for notifications. It replaces paid tools like Bloomberg Terminal or FactSet for data ingestion but lacks their depth in real-time feeds and proprietary research.

Open Data Platform by OpenBB (ODP) is the open-source toolset that helps data engineers integrate proprietary, licensed, and public data sources into downstream applications like AI copilots and research dashboards.

ODP operates as the "connect once, consume everywhere" infrastructure layer that consolidates and exposes data to multiple surfaces at once: Python environments for quants, OpenBB Workspace and Excel for analysts, MCP servers for AI agents, and REST APIs for other applications.

Get started with: pip install openbb

from openbb import obb
output = obb.equity.price.historical("AAPL")
df = output.to_dataframe()

OpenBB Workspace

While the Open Data Platform provides the open-source data integration foundation, OpenBB Workspace offers the enterprise UI for analysts to visualize datasets and leverage AI agents. The platform's "connect once, consume everywhere" architecture enables seamless integration between the two.

You can find OpenBB Workspace at .

Integrating Open Data Platform to the OpenBB Workspace

Connect this library to the OpenBB Workspace with a few simple commands, in a Python (3.9.21 - 3.12) environment.

Run an ODP backend
  • Install the packages.
pip install "openbb[all]"
  • Start the API server over localhost.
openbb-api

This will launch a FastAPI server, via Uvicorn, at 127.0.0.1:6900.

You can check that it works by going to .

Integrate the ODP Backend to OpenBB Workspace

Sign-in to the OpenBB Workspace, and follow the following steps:

CleanShot 2025-05-17 at 09 51 56@2x

  1. Go to the "Apps" tab
  2. Click on "Connect backend"
  3. Fill in the form with: Name: Open Data Platform URL:
  4. Click on "Test". You should get a "Test successful" with the number of apps found.
  5. Click on "Add".

That's it.
