Free, for good
r12d doesn't charge, doesn't run ads, and doesn't sell or share data about you or the people who scan your codes. It's a noncommercial project, paid for out of pocket by the people who run it, on hardware they own.
There are no paid plans and none are coming. Workspaces have fair-use limits, like the number of codes, to keep the service running for everyone. If you need more, ask.
Invite-only while we're in beta.
