All Things Open 2026
This conference has always been one of our favorites — maybe our actual favorite.
As we’re publishing this, Todd Lewis and his team are just announcing “round four” speakers, and suffice it to say that the speaker lineup so far this year looks to be super. As always, it’s broad of scope — featuring just about any subject that could fall under the open source heading — featuring speakers who are both familiar (folks like Frank Karlitschek, Jim Jagielski, Brad Topol, Michael Hall, Ruth Suehle, Mark Hinkle, Jay LaCroix, Matt Asay, and more, and fresh faces that in one way or another are open source and free software movers and shakers with plenty of information and insight.
As we go to press with this listing, speakers are still being chosen and added to the list on the ATO 2026 website.
Change of Format
After 14 years, All Things Open is going to change formats.
Where in the past the conference has opened with a bunch of free co-located events on Sunday, followed on Monday and Tuesday by a two-day conference featuring traditional conference presentations of about 45 minutes each on a number of tracks (last year there were 18), this year they’re moving the co-located events to Monday to take place simultaneously with the conferences first day.
The first day’s conference format is also changing. Instead of 45 minute presentations, Monday will feature 2-hour deep dive sessions on a variety of open source technology and process topics, as well as three all-day AI-specific workshops: AI for DevSecOps, AI Agents & Vibe Coding, and AI Agents & Model Context Protocol. Tuesday will be a “regular” conference day with traditional 45-minute presentations.
We’re guessing that Tuesday is likely to have a larger media presence, so we’re expecting any newsworthy keynote announcements to happen then.
For Tuesday, the event is promising 18 tracks and over 100 speakers.
