The Awesome Nostr category Offline signers is part of the broader public project map. This page keeps the source links visible and adds Crays interpretation.

Category role

This category matters because it groups related Nostr projects around offline signers. It is useful for breadth: readers can see how many independent teams, tools and experiments orbit the protocol.

The Crays archive uses this as a discovery layer, not as a final judgment. Every link should be checked for activity, license, security posture and strategic relevance before becoming a product dependency.
