OpenBB: The Open Source Challenger to Bloomberg

In the world of finance and investment research, Bloomberg Terminal has long been the go-to platform for professionals. However, a new player has emerged in the market – OpenBB. OpenBB aims to be an open source challenger to Bloomberg Terminal, offering an alternative that is affordable, highly customizable, and built on Python [4]. This article will delve into the features and advantages of OpenBB, exploring why there is a need for an open source investment research platform.

Advantages of Open Source

One of the key advantages of OpenBB is its open source nature. By being open source, OpenBB allows the broader community to contribute and add their own flavors to the platform [2]. This means that users can customize and tailor the platform to suit their specific needs, making it a highly flexible solution [3]. Additionally, being open source fosters collaboration and innovation, as developers can build upon each other’s work and create new functionalities [2].

Customizability with Python

OpenBB’s foundation in Python further enhances its customizability. Python is a popular programming language known for its simplicity and readability. It allows users to easily modify and extend the functionality of OpenBB according to their requirements [3]. For example, a contributor interested in the foreign currency exchange market integrated an Oanda integration into OpenBB [2]. This level of customization sets OpenBB apart from traditional platforms like Bloomberg Terminal, which may have limited flexibility due to their closed-source nature [4].


Another significant advantage of OpenBB is its affordability. While platforms like Bloomberg Terminal come with hefty price tags, OpenBB offers a cost-effective alternative without compromising on features [3]. This accessibility makes OpenBB an attractive option for individuals and organizations that may not have the financial resources to invest in expensive proprietary software [4]. By democratizing access to investment research tools, OpenBB aims to level the playing field and empower a wider range of users.

Community-driven Development

OpenBB’s open source nature also fosters a community-driven development model. The platform benefits from the collective knowledge and expertise of its contributors, who continuously improve and enhance its features [2]. This collaborative approach ensures that OpenBB remains up-to-date with the latest industry trends and technological advancements. Users can actively participate in shaping the future of the platform by providing feedback, reporting bugs, and contributing code [4]. This community-driven development model creates a sense of ownership and engagement among users, fostering a vibrant ecosystem around OpenBB.


OpenBB is positioning itself as a strong contender to Bloomberg Terminal by offering an open source alternative that is affordable, highly customizable, and built on Python. Its open source nature allows for flexibility and customization, enabling users to tailor the platform to their specific needs. The use of Python further enhances its customizability, making it easy for users to modify and extend OpenBB’s functionalities. By democratizing access to investment research tools, OpenBB aims to empower a wider range of users and foster a community-driven development model. As the finance industry continues to evolve, platforms like OpenBB provide an exciting opportunity for innovation and collaboration.
