openbb
An open-source data platform that integrates proprietary, licensed, and public financial data sources for analysts, quants, and AI agents.
What is openbb?
Open Data Platform by OpenBB (ODP) is an open-source financial data integration platform that consolidates proprietary, licensed, and public data sources into a unified infrastructure. It solves the problem of fragmented financial data access by providing a single point of integration for downstream applications like AI copilots, research dashboards, and quantitative tools.
Data engineers, quantitative analysts (quants), financial researchers, and developers building AI agents or applications that require integrated financial data.
Developers choose ODP for its open-source, "connect once, consume everywhere" architecture that eliminates data silos and provides consistent access across Python, Excel, REST APIs, and AI agent interfaces. It reduces integration complexity while maintaining flexibility for both local and cloud deployments.
Overview
Financial data platform for analysts, quants and AI agents.
Use Cases
Best For
- Integrating multiple financial data sources into a single Python workflow
- Building quantitative research tools that require real-time and historical market data
- Developing AI agents (via MCP servers) that need access to financial datasets
- Creating custom financial dashboards or research platforms
- Self-hosting a financial data API for internal applications
- Connecting proprietary data to the OpenBB Workspace for visualization
Not Ideal For
- Projects requiring only simple, free API access without data consolidation, as ODP adds integration overhead
- High-frequency trading systems where ultra-low latency is critical, due to potential delays from the infrastructure layer
- Teams avoiding copyleft licenses like AGPLv3 for proprietary software development
- Applications focused exclusively on non-financial data, as ODP is tailored for market and economic datasets
Pros & Cons
Pros
Consolidates proprietary, licensed, and public financial sources into a single platform, reducing fragmentation and simplifying data engineering workflows.
Exposes data simultaneously to Python environments, Excel, REST APIs, and MCP servers for AI agents, enabling diverse application development.
Provides a dedicated Python package (`openbb`) for direct data access and manipulation, catering to quantitative analysts and script-based workflows.
Includes a FastAPI server that can be run locally for backend integration and testing, offering control over data privacy and customization.
Cons
The AGPLv3 license requires derivative works to be open-sourced, which can be a barrier for commercial projects wanting to keep code proprietary.
Tight integration with OpenBB Workspace and tools may create dependency, limiting flexibility if switching to alternative platforms in the future.
Installing the full package with `openbb[all]` and running the local API server involves multiple steps, which can be overkill for simple data fetching needs.
