No, really: Invite anyone to your tailnet
Blog post from Tailscale
Tailscale has introduced a significant update to its user invite system, allowing users to invite anyone to their tailnet, regardless of their authentication method, effectively removing previous limitations associated with GitHub-based tailnets. This change marks the culmination of efforts to enhance multi-user personal tailnets, which were first introduced for up to three users for free. The update broadens the accessibility of tailnets to include friends, family, and collaborators, promoting a more engaging and communal use of Tailscale's networking capabilities. The company highlights the diverse user base that includes both individuals and businesses, with many individuals bringing Tailscale into their professional environments after experiencing its benefits at home. The update aims to foster greater connectivity and resource sharing, as exemplified by users sharing media servers, DNS rules, and gaming servers with others.
