The State
of the
Octoverse

This year, collaborating more than ever before, with 1.1 billion contributions—and counting.

You’re transcending borders and barriers of all varieties to create something unquantifiable: a community of leaders, dreamers, dissenters, tinkerers, and doers building the way forward.

To celebrate a year of teamwork across time zones, programming languages, and billions of lines of code, let’s take a look back on the communities and projects you’ve created in 2018. 2018 is defined as the last 365 days from the last Octoverse release, Oct 1st 2017 through Sept 30th 2018.

> Overview

31 M+
developers
building on GitHub—including more new users in 2018 than in our first six years combined. “Developers” refers to the total number of user accounts on GitHub as of September 30, 2018, regardless of their activity status.

2.1 M+
organizations
bringing people together. There are 40% more organizations on GitHub this year than lastyear. “Organizations” refers to the total number of paid and free organization accounts created, including active and inactive accounts as of September 30, 2018.

96 M+
repositories
hosted on GitHub, 40% more than last year. Almost one third of all repositories were created in the last year. “Repositories” and “new repositories” include the public and private repositories you’ve forked as of September 30, 2018.

200 M+
pull requests
created, ever. And you created more than one third of these in the last 12 months alone. “Pull requests” refers to the total number of pull requests created in public and private repositories, excluding those created by spammy users.

Defining terms in Octoverse 2018

Throughout our Octoverse report, you’ll see a few key terms and phrases come up. These provide a consistent framework for how we collect and describe our data within the report.

  • 2018: A year in this report is the last 365 days from the last Octoverse release, Oct 1st 2017 through Sept 30th 2018.
  • Apps: Apps or applications refer to both OAuth Apps and GitHub Apps.
  • Developers: Developers are individual user accounts on GitHub, regardless of their activity.
  • Location: Country information for users is based on the country their IP address resolves to. For organizations, we take the best known country information either from the organization profile, or the most common country organization members are active in. We only use location information in aggregate form to look at things like trends in growth in a particular country or region. We don’t look at location information granularity finer than country level.
  • Open source projects: Open source projects are public repositories with a license file detected by Licensee, regardless of the type of license a project has chosen.
  • Organizations: Organization accounts represent collections of people on GitHub. These can be paid or free, big or small, businesses or nonprofits.
  • Projects and repositories: We use projects and repositories interchangeably, although we understand that sometimes a larger project can span across several related repositories.

2018 is shaping up to be an extraordinary year.

The GitHub community is growing, contributing, and collaborating more than ever before. But what’s behind your commits? Maybe you’re learning something new—or trying something no one has ever done before. Whether you create because you’re working toward a goal or you just see a way that’s better, you’re doing it on GitHub.

Thank you for the evenings you put in, the weekends you’ve dedicated, the ideas you’ve committed, the code you’ve crafted, and the future you’re building for us all. We can’t wait to see what you build next.
