Github 2021 Report
In this year’s Octoverse Report, our research tells you how to improve your performance and well-being by developing code, creating documentation, and supporting communities in smarter, more sustainable ways.
For the first time, this research combines telemetry from 4M+ repositories and surveys from more than 12,000 developers.
This approach reveals current trends and also gives us predictive results–we can now see with more precision how to achieve successful outcomes for developers, teams, organizations, and communities.
