Project sources
- Curated lists (more useful):
- Google Summer of Code mentoring projects
- A few of the projects OpenHatch mentors have helped with before: WelcomeBot, OpenStreetMap, Oppia (source, contribution guide, getting started, tasks for new contributors).
- Even the Open Source Comes to Campus curriculum itself!
- Large lists/databases (less useful):
- A directory of open source directories
You can also do a web search for “[topic] open source” or “[topic] free software” and see what turns up.
