Good first issues labels/good first issue Discussions setup · ideas · show-and-tell Roadmap milestones/ Sponsor github/sponsors/dmellok Why AGPL, and what your server sends The AGPL keeps the server free even when run as a service. No accounts. Online features are off by default — nothing is sent unless you enable them under Settings → System → Online features. With them on, the app contacts api.tesserae.ink for update checks and an anonymous count of which marketplace widgets are in use; a coarse country is derived from the IP, then discarded. Read the source Read the privacy page Security policy Why I built it Beautiful ambient displays, tied to nobody's cloud. Tesserae grew from a weekend project into a plugin platform spanning several hardware families and rendering pipelines. A solo project, built in Melbourne.
