The Wikimedia Toolserver is a collaborative platform providing Unix hosting for various software tools written by and used for Wikimedia editors. The service is operated by Wikimedia Deutschland e.V. with assistance from the Wikimedia Foundation.
Both Wikimedia Deutschland e.V. and the Wikimedia Foundation are non profits which rely on donations for income.
If you like, you can donate hardware specifically for the toolserver. If you would like to do this, please contact <river (at) wikimedia (dot) org>.
