About Sustain

It all started with a tweet in November 2016. Six months later, one hundred people gathered in San Francisco and created a cultural shift in how we think about the sustainability of open source software.

After the event, a report was written and a definition was born, "sustainer—the individual or organization who is concerned with the fragile state and future of highly-used and impactful open source projects". If that sounds like something you identify with, you should join us.

Sustain events are led by a facilitator. There are no keynotes, talks, or sponsor demos. Undivided attention is required. Phones and laptops are put away throughout the day.

What this means is that Sustain is a different sort of conference, and that participants are fully engaged. Since 2017, the Sustain community has held events around the globe. As well as events, Sustain also hosts a semi-weekly podcast, and facilitates working groups getting into the weeds of what sustainability means.

Join us!


Sustain is open source, and anyone can join. However, there tends to be a core group involved in organizing the events and work.

Past organizers include:
