The OLF Conference is proud to announce that we will hold our 23rd annual event in Columbus, Ohio on December 6, 2025.
OLF welcomes all Free and Open Source Software professionals, enthusiasts, and everyone interested in learning more about Free and Open Source Software. On-site attendance is limited. For this reason, there is an advance $10 “Enthusiast” level registration price to reduce no-shows. (With free tickets, about 50% of registrants were no-shows, which is not something we can have this year.) Online attendance remains at $10 suggested donation. If cost is a concern, you could also consider volunteering to help out at the event or requesting a scholarship.
Before registering for an in-person ticket, be sure to review our safety plan and attendance policy first.
Note that you should register in advance; walk-ins will start at $20 for the Enthusiast Pass. Seats are limited and may sell out.
In-Person Ticket sales will close at 12:00pm Eastern time on December 4 or when ticket inventory runs out, whichever comes first.
The following table shows what you get with each registration level:
| Supporter | Enthusiast | A-la-cart | |
|---|---|---|---|
| Exhibits | ★ | ★ | |
| Keynotes and talks | ★ | ★ | |
| Friday December 5 Happy Hour | ★ | $20 | |
| Lunch voucher | ★ | ||
| Souvenir T-shirt | while supply lasts | while supply lasts |
The Online Only Pass will let you access our streamed content as well as a Slack invite for more interactive experiences.
T-shirts for pickup as a separate product is open for a limited time only – likely to close on Monday December 1.
We’ll try to order a few more shirts to sell in person but popular sizes will not last. These funds go directly back to making this conference possible. Thank you.
We are looking forward to seeing you on December 6, 2025 at the Sonesta Downtown Columbus.
