Mailing List

We have two mailing lists: one for users running Stratosphere and the other one for developers. You can ask questions by sending an email to one of the following adresses:

The users list does not require signup to ask questions (just send an email), whereas the dev list does. Sign up by following the link to Google.

To unsubscribe, send an email to or respectively.

Use the users mailing list for all general questions, e.g. how to run the system or best development practices. Please report bugs in the developer mailing list.


Open an Issue on our GitHub page for bugs, documentation or website issues.


For project management issues, organizational questions, and university/corperate collaboration requests, please contact the speaker of the Stratosphere project, as found on our Legal page.
