The OpenWrt/LEDE Project relies on the considerable efforts of its volunteer developers, the core documentation team, the forum moderators, and the host of people who're actively using and testing the products. The OpenWrt/LEDE team has also provisioned many physical and virtual servers that “make the OpenWrt (and former LEDE) Project go.”
We run the following resources and services to support the OpenWrt Project.
Buildbot machines detect updates to the source and kick off the build process for each supported device.
All these services run on machines devoted to the OpenWrt/LEDE Project.
There is a private discussion about possibilities of some sort of crowdfunding to allow the community to pay back the core team for their expenses, and fund the project going forward, but there is no public news yet.
