OpenZFS User and Developer Summit 2025

Come join us for our thirteenth annual OpenZFS Developer Summit and second annual OpenZFS User Summit.

Enjoy two days of experts using OpenZFS in production discussing their successes and challenges, followed by a traditional day of parter presentation and full-day hackathon.

We will have social events of various sizes and many opportunites for small-group discussions and hacking.

The ticket price includes all four days and we encourage user and developer engagement.

We welcome diverse, positive perspectives as our community becomes richer, and we're committed to creating an environment where all people feel welcome.
