The Open Source Analytics Conference (OSA CON) brings together data engineers, analysts, product managers, and builders shaping the future of open-source analytics.
It’s all about accelerating AI while celebrating the tools and communities that make modern data stacks possible. Expect candid talks from open‑source innovators rather than product pitches.
When & Where
OSA CON 2025 takes place online on November 4–5. It’s completely free to attend. Sessions run in your local timezone on Airmeet, and full replays will be available right after the event.
Who It’s For
If you work with data, whether as a data scientist, engineer, analyst, designer, or product manager, OSA CON is for you.
It’s also a great space for open‑source maintainers, contributors, and decision‑makers to connect.
