Open Source

Open source is core to our DNA

Posit was founded with the mission to create open source software for data science, scientific research, and technical communication. We don’t just say this: it’s fundamentally baked into our corporate charter as a Public Benefit Corporation. Our imperative is not growth at all costs, but rather to build a company that will still be here fulfilling its mission in 100 years.

Scaling open source, a model that works

We have created a sustainable model for funding our mission. The packages, protocols, and file formats we develop will always be open source and available to all. As these open source tools become widely adopted, this creates an opportunity to sell complementary products that help in their adoption at scale, the proceeds of which fund further open source development.

We're dedicated to open source

The best way to achieve meaningful progress is to put the power of open source data science tools in the hands of everyone who needs them. Starting with you.

Open source software is resilient.

It’s developed collaboratively by the global community. With open source, you’re not chained to the fortunes of a single company, and you own not just your work, but all the code needed to run it.

Open source software is participatory.

You’re not limited by the vision of one company and the methods they support; you’re free to pick and choose from a vast palette of options or even develop your own.

Open source software is free.

It’s accessible to everyone, regardless of economic means. This is particularly important for science where the ability to reproduce and critique the work of others is essential for progress.

Always Open

We write open source software, and we always will

40% of Posit engineers work full-time on open source software, and many others contribute part-time. We create tools used by millions. Here are just a few.

RStudio IDE

Used by millions of people weekly, the RStudio IDE is a set of tools built to help you be more productive with R and Python.

tidyverse

The tidyverse is an opinionated collection of R packages designed for data science. All packages share an underlying design philosophy, grammar, and data structures.

The University of Toronto is scaling specialized bioinformatics education to a global audience by providing 43,000 students with a cloud-based RStudio environment via Posit Workbench. By moving complex RNA-seq analysis to a web-accessible instance on AWS, the program has eliminated the technical friction of local software dependencies, allowing students to focus on biological insights rather than installation issues.

The University of Oxford is empowering its researchers to transform static datasets into dynamic, interactive visualizations through its Interactive Data Network. By leveraging R and Shiny, academics across disciplines—from tracking the modern gig economy via the Online Labour Index to mapping ancient Roman shipwrecks—are making their research more accessible and reproducible for the global scientific community.
