Open Source Citizenship

What are the rights and responsibilities of an open source citizen? We’re exploring what open source means to us, what it offers, where we struggle, and why we do this day in and day out, even when we’re not paid for it.

Innovative Track Structure

Our session tracks are technology agnostic, based around shared community experiences and focus on the similarities between projects, not the differences. View the tracks.

Hacker Lounge

The geekery doesn’t end when the sessions do. We’re also running a hacker lounge for code sprints, bug bashes, bouncing ideas, starting new projects or just mingling and taking in the vibe.

100% Volunteer-Run

Your software is peer-produced. Why not your conference? Open Source Bridge is pioneered and planned by a team of open source developers and technologists. What’s more, we’ve built an open source application to manage talk proposals.

We need your help! Volunteer through our webapp for 8 hours or more to earn a free registration code for this year. Do it Now!

2017 Registration and Call for Proposals are open!

Open Source Bridge, the conference focused on building open source community and citizenship, is returning for 2017! Join us from June 20–23 in Portland for four days of technical talks, hacking sessions, and opportunities for collaboration. Early bird registration is now open.

Want to speak or present a workshop? We’d love to hear from you! Along with registration, our call for proposals is open through March 31st.

We’re changing things up a little this year, given the political, cultural, and economic crossroads we find ourselves at right now. We’ve added a new track to explore how activists are using technology, how open source communities are supporting activists, and how other open source and activist communities intersect. In addition to the usual Culture, Hacks, Practice, and Theory topics, we want you to submit proposals about projects and people actively working toward making this world better. We welcome more long-form workshop sessions too, for those who want to share their work and how to replicate the process.

Outside of the talk schedule, we’re looking to expand our extracurricular activities. If you’re interested in leading a group to dinner or on a field trip, or in gathering an evening Birds of a Feather session, email

Open source work is inherently collaborative. To encourage new connections, we’re holding a project night in the Hacker Lounge and want to partner with community groups and individual projects looking for new contributors. Interested? Email and come prepared with tasks that newcomers can jump in on.

Another new angle this year is the inclusion of a Community Organizer track to our Friday Unconference day. It will be similar in practice to OSCON’s Community Leadership Summit, with a focus on inclusion, intersectionality, accessibility, management, onboarding, documentation, crisis management, and more. We want to share and learn from others in leadership positions, to help each other rise up and know that we are not alone.
