The Symphony program is focused on interoperability of tools and applications built on top of the Symphony platform
Open Source Readiness
The Open Source Readiness (“OSR”) program helps address the unique obstacles financial services firms face with open source collaboration - legal & regulatory concerns, internal policies, cultural friction, and heavily restricted technology environments.
Data Technologies
This program supports open collaboration for technology and tools supporting common uses of data across the full lifecycle of financial services - including but not limited to data acquisition, storage, governance, processing, and distribution.


Overcoming Obstacles to Open Source

Financial services firms may face various barriers, both real and perceived, that impede adoption of Open Source software and related software development practices. These obstacles include:
  • Corporate strategy considerations about maintaining competitive advantage and protecting trade secrets ("How can we compete if anyone can see our code?")
  • Legal & regulatory concerns
  • Incompatible internal policies
  • Cultural friction
  • Inhospitable technical environments and resistance from corporate IT departments

If you'd like to get engaged, please reach out to FINOS General Counsel and Open Source Readiness PMC Lead Aaron Williamson or subscribe to the OSR Program General List.


A goal of the Foundation is to collect, curate, and share leading practices and practical tools that have helped financial services firms (and leading companies from other industries) to adopt Open Source software practices.

FINOS helps its members organizations achieve efficient and compliant open source software strategic engagement as part of our Member Success initiatives, and is just one of many Membership Benefits.

Getting Developers Connected to Tools and Practices

Just as organizations working in financial services may face unique obstacles when first using Open Source, developers building in (or for) the financial services industry often encounter challenges that their peers in other sectors may not face, or at least not to the same degree. These may include:

  • Firewalls that block access to popular code repositories
  • Traditional project management techniques and tools   
  • Mandated testing tools, frameworks, and practices
  • Compliance and IT audit policies

Helping financial services developers get trained and productive with Open Source, and improving the overall financial services developer experience for both new and experienced professionals, is central to our mission. 

The Open Developer Platform (ODP)

To help financial services developers working with open source, FINOS created the Open Developer Platform (ODP)The Open Developer Platform (ODP) is a collaborative initiative that delivers a secure and compliant sandbox for software development in the financial services world.
