MeowCAD
Like other cloud-based EDAs, updates to schematics and boards communicate back to MeowCADs central server and are saved persistently, giving the ability to work on electronics projects anywhere there's a web browser and internet connection. MeowCAD is running online now and people who want to try it out can register for an account or go directly to the schematic capture and board capture portions to play around. MeowCAD is the first completely free and open source, software-as-a-service, electronic design tool and provides a free and open source alternative where there wasn't one before. Ultimately, the value of an online electronics design community comes from its members. People are encouraged to fork the project, stand up their own servers, or just use MeowCAD directly to create their own electronics projects and share with the community.
