A mobile preview of the Posit Open Source website front page.

For over 15 years, Posit has been building wonderful open source software and content. Over the years, that wealth of knowledge expanded across hundreds of package sites, dozens of blogs, and multiple YouTube channels. While this rapid, creative growth was wonderful, it also created a practical problem: it became difficult for you to keep up with it all.

Today, we are changing that. I am very excited to announce the Posit Open Source website, opensource.posit.co. I am incredibly proud of the team that built it.

This new central hub connects you to our open source software, blog posts, videos, events, and cheatsheets. As of today, it includes:

  • 900+ blog posts, originally published across a dozen blogs, are now consolidated into a single, unified open source blog.
  • 1,600+ videos gathered from multiple YouTube channels are now in one place and fully transcribed.
  • 300+ package profiles with links, contributors, and related resources.

If you would like more details, check out the announcement blog post on the Open Source website.

The new website is open source because we want the community to contribute. If you have any feedback or suggestions, please open an issue on our GitHub repository.

Head over to opensource.posit.co to explore the new site. I hope you like it.
