Go deeper into open source software development.

There's a reason industry legends come to the O’Reilly Open Source Software Conference to share their ideas. Some of those ideas have launched careers and collaborations—and sparked new ideas leading to some of the most innovative technologies in open source.

If you want to explore some of the most challenging issues that our industry faces today, including rock-solid technical skills, business-tested use cases, detailed success stories (or tear-downs of failures), come to OSCON.

O’Reilly has a reputation for geekiness. We’ll own it. We know you don’t just want to hear about a technology–you want to roll up your sleeves and use it. We do, too. From deep-dive tutorials to practical keynotes, we have a relentless focus on the tools and techniques you can put to immediate use.


Get a clear, vendor-neutral look at the tools, best practices, and processes you need to make solid decisions and deliver effective software. From emerging languages and frameworks to the cloud and AI–if it’s enabling advancements in software, it’s covered at OSCON.


The most brilliant software can be hamstrung by the most mundane obstacles. At OSCON, you’ll get clear advice on how to avoid expensive and time-consuming bottlenecks, case studies to learn how others overcame the hurdles you face, and a chance to test-drive new tools. So you can focus on innovation, not irritation.


Ever since the very first 1998 Freeware Summit (where the term open source was coined), O’Reilly has gathered this community to exchange ideas and build connections. You’ll meet the inventors and innovators–and the people who share your headaches and understand what rocks your world.


The conference will take place at the Oregon Convention Center, a short light rail or streetcar ride away from top restaurants, tax-free shopping, and quirky attractions. Reserve your room by June 30 and save.

Diversity and inclusion at O'Reilly Open Source Software Conference

At O’Reilly, we believe that true innovation depends on hearing from and engaging with people with a variety of perspectives. Read our Diversity Statement and learn about our Diversity & Inclusion scholarship program. The conference takes place in an ADA-compliant venue where we provide a nursing room; we also live-caption the keynote presentations and offer childcare expenses reimbursement.
