Mirlo is an open-source platform on which artists sell digital and physical music and merchandise, receive recurring support from fans, manage mailing lists and post updates to supporters. Artists decide what percentage of each sale goes to the platform. Payments run through Stripe, and music can also be offered free. Labels are covered too, and the FAQ compares the service with Bandcamp and Patreon. NLnet funding under the EU's NGI Zero programme supports federating Mirlo instances with each other and the wider fediverse through ActivityPub.
Mirlo is maintained by a worker-owned cooperative that, by its own account, is legally incorporated in the United States. The code is released under the AGPL-3.0 or later, and the documentation explains how to install it on your own server with Docker. The hosted service at mirlo.space runs its API and background jobs on Render and stores files at Backblaze, both US companies; the Render configuration in the repository names the Oregon region, and the documentation states no region for Backblaze.
