Open Source Analytics Community
Talk shop with the people building open-source analytics
Engineers, maintainers, and practitioners working on open-source data and AI infrastructure — meeting up a few times a year, plus talks, an active Slack, and OSA Con. Project-neutral, no hype.

Community in motion
People in rooms, talking about how they actually build
A few times a year we get in a room together — San Francisco, New York, Chicago, Brussels. Small meetups, hands-on workshops, hallway debugging, and talks from engineers running analytics in production. Slack and online sessions carry it the rest of the year.

One day of anti-hype technical talks from engineers building open-source analytics and AI infrastructure. Everything else on this site is what happens the other 364 days.
A project-neutral forum for the people building open-source analytics
We believe analytics software should be free to use and extend, and that the best tools should work together without proprietary barriers or unjust pricing. OSA COM is open to all open-source developers, vendors included, and beholden to none.
