Open Source Fintech Infrastructure Software

Fintech Infrastructure software provides the underlying systems for managing financial data flows, payment processing, and banking operations. These tools enable the integration of public market data with internal records to support quantitative research and automated financial agents. Developers and merchants use this type of software to build custom transaction pipelines and handle cryptocurrency payments. Self-hosting these apps ensures that sensitive transaction histories and private API keys remain on internal servers rather than on external cloud platforms.

This page lists 4 open source tools in the Fintech Infrastructure category. The most popular are OpenBB, Bitcart and Formance. Most use the MIT or AGPL-3.0 license, and 3 offer an official Docker image.
