Open source software pervades the work we do at Uber. On the infrastructure side, we have contributed projects like Jaeger, which lets engineers trace complex architectures, and M3, a metrics platform that works with Prometheus. For front-end development, we built RIBs, a cross-platform architecture for mobile apps, along with Fusion.js, a plugin-based web framework.
In the rapidly advancing area of machine learning, we have open source tools such as Horovod, a distributed training framework, and Pyro, a deep probabilistic programming language written in Python.
