Github's top open source projects for 2018 include Tensorflow, IT automation tool Ansible and Kubernetes with the fastest growth in areas such as machine learning, 3D printing and data analysis.

The rankings were part of Github's Octoverse report, which was launched along with a bevy of Github updates. Github, now part of Microsoft, ranked the top open source projects based on unique contributors between Oct. 1, 2017 and Sept. 30 across 96 million global software projects. The top open source projects included:

Microsoft/vscode
facebook/react-native
tensorflow/tensorflow
angular/angular-cli
MicrosoftDocs/azure-docs
angular/angular
ansible/ansible
kubernetes/kubernetes
npm/npm
DefinitelyTyped/DefinitelyTyped

And the fastest growing open source projects included Microsoft Docs/azure-docs, pytorch/pytorch and godotengine/godot to name a few. Here's the complete breakdown and the change in growth from the previous year.

New projects that launched often revolved around algorithms for machine learning. Google's Dopamine project, a framework for prototyping reinforcement learning algorithms, and Facebook Research's Detectron, which covers object detection algorithms.

Github also highlighted the fastest growing languages. Common themes were machine learning, interoperability and DevOps. Here's a look at the fast growing languages.

Kotlin
HCL
TypeScript
PowerShell
Rust
CMake
Go
Python
Groovy
SQLPL

Other Github tidbits by the numbers:

The platform saw 30 percent growth in the ecosystem over the past 12 months;
By category continuous integration and security, code quality and project management were popular areas.

The Octoverse report comes as Github announced a bevy of developer tools. These tools include Github Actions, an area where code can be built, share and executed inside containers; a Security Advisory API to automate security scanning; vulnerability alerts for Java and .Net projects; and Github Connect, which allows business customers to better connect with the open source community.
